Looks like you may be receiving some custom content as a subscriber then.
I don't get anything like that. E.g. no "roundedYellow" and the only instances
of the word "privacy" don't have either of the contexts shown above.

In any case the most likely explanation for this is a problem with MTU size.
You're going to have difficulty finding the correct size to use though
because all of the tests that I know of for determining it rely on ping -f -l
I think you should check with your ISP for help. Very likely this would be
an issue which other subscribers would have already had to deal with.

See this post for my previous comments on that possibility.
As I indicated there a better newsgroup for resolving it would be
one which specializes in networking for your OS.

Often that is a symptom of either a page which is only designed to redirect
but is blocked from doing so from some reason or there is a problem with
the transmission of the full page. In either case you could check with View
Source (Alt-V,c) to see how "completely blank" your page really is.
E.g. if you don't see </HTML> at the bottom of the source file IE would not
render it and would show you a blank page.

Can anybody help please.

FYI that site does not use redirect. You can tell that by examining the browse
stack (e.g. via the Back button dropdown list) but I also I traced it with Fiddler2.
The size of the HTML file was 31,033. However, that number may only be
coming from the response's Content-Length: header. Unfortunately the page
is marked non-cacheable (no-cache) so it doesn't show in the TIF Viewer
(Alt-T,O,Alt-S,V) but the View Source instance would and its properties would
show you a very good approximation of the page's length. E.g. viewed that way
the Size: appears as 30.3KB

Also, FWIW when I view that page's source with Notepad with Word Wrap off
and the Status bar on and press Ctrl-End, I see Line 406 in the Status bar
(with the </HTML> tag just above it.)

Robert,

If the problem is with MTU, it's the client MTU setting. It's not too difficult
to determine the right value. If you do it methodically, you can have it in 10
minutes.

http://nitecruzr.blogspot.com/2007/06/determining-mtu-to-single-server.html

I'm not so sure that getting a Blockbuster web page with a yellow border around
the Privacy Statement indicates MTU though. That may be a Blockbuster question.

I'm not so sure that getting a Blockbuster web page with a yellow border around
the Privacy Statement indicates MTU though. That may be a Blockbuster question.

Chuck,

Thanks for joining in. There are two main symptoms so far.

Paul (the OP) seems[1] to be showing (via View Source) of IE7's
attempt to open http://www.blockbuster.co.uk/ that the HTML
may be truncated (e.g. the View Source doesn't contain an ending
</HTML> tag.)

[1] He didn't exactly prove that or tell me what line he copied down to
but that is what I assumed could be inferred by the sentence:

Quote:

As you can see not much....

I gave hints for setting up Notepad to show line and column numbers
and for seeing the size of the received file so we may yet get more
specific confirmation about this.

The other point is that the source extracts Paul does show are not elements
which appear when I try that URL. That was my point about the "roundedYellow"
etc. So we don't know how that arrives or where it occurs. E.g., I suppose I could
have suggested he actually search for an </HTML> end tag instead of just go to
the bottom of the source. If there is an </HTML> end tag before that the symptom
may be something entirely different.

Therefore, assuming that that last possibility is unlikely and that the "not much"
comment was sufficient cause to think about a corrupted or truncated transmission
I decided to elicit some help on the networking side. <w> The reason I suggested
checking with the ISP instead of the Blockbuster site is because the ISP will be
closer. E.g. if the problem is occurring in an intermediate node Blockbuster
may be unlikely to want to help. Also the the ISP is what he will be paying money to... ; )

Thanks for the link.

I have already run the network setup wizard, made sure they are on the same
workgroup, that they have unique names, that they are running the browser
service. I cannot for the life of me figure out why it is not working
correctly. Before I added XP Pro PC 2, the other two would work fine. I don't
know if that is a coincidence or not.

Any help would be greatly appreciated.

Both other computers can access PC 2's shares directly, so I don't
think that the problem has anything to do with permissions, or with
"RestrictAnonymous" as another reply to your question suggested.

Does "My Network Places" on PC 1 and XP Home PC have shortcuts to
shares on PC 2? I've seen such shortcuts "go bad" for no apparent
reason. Right-click and delete the shortcuts, use "Add a network
place" to re-create them, and try accessing the PC 2 shares again.

Make sure that NetBIOS over TCP/IP is enabled on all computers:

1. Open the Network Connections folder.
2. Right click the local area network connection and click Properties.
3. Double click Internet Protocol (TCP/IP).
4. Click Advanced.
5. Click WINS.
6. Click the Enable NetBIOS Over TCP/IP button.

Run "ipconfig /all" on each computer and look at the "Node Type" at
the beginning of the output. If it says "Peer-to-Peer" (which should
actually be "Point-to-Point") that's the problem. It means that the
computer only uses a WINS server, which isn't available on a
peer-to-peer network for NetBIOS name resolution.

If that's the case, run the registry editor, open this key:

HLM\System\CurrentControlSet\Services\Netbt\Parameters

and delete these values if they're present:

NodeType
DhcpNodeType

Reboot, then try network access again.

If that doesn't fix it, open that registry key again, create a DWORD
value called "NodeType", and set it to 1 for "Broadcast" or 4 for
"Mixed".

also to add my page is a complete blank, no error message just
hanging as though it is struggling to load.

Often that is a symptom of either a page which is only designed to redirect
but is blocked from doing so from some reason or there is a problem with
the transmission of the full page. In either case you could check with View
Source (Alt-V,c) to see how "completely blank" your page really is.
E.g. if you don't see </HTML> at the bottom of the source file IE would not
render it and would show you a blank page.

Can anybody help please.

FYI that site does not use redirect. You can tell that by examining the browse
stack (e.g. via the Back button dropdown list) but I also I traced it with Fiddler2.
The size of the HTML file was 31,033. However, that number may only be
coming from the response's Content-Length: header. Unfortunately the page
is marked non-cacheable (no-cache) so it doesn't show in the TIF Viewer
(Alt-T,O,Alt-S,V) but the View Source instance would and its properties would
show you a very good approximation of the page's length. E.g. viewed that way
the Size: appears as 30.3KB

Also, FWIW when I view that page's source with Notepad with Word Wrap off
and the Status bar on and press Ctrl-End, I see Line 406 in the Status bar
(with the </HTML> tag just above it.)

Robert,

If the problem is with MTU, it's the client MTU setting. It's not too difficult
to determine the right value. If you do it methodically, you can have it in 10
minutes.
http://nitecruzr.blogspot.com/2007/06/determining-mtu-to-single-server.html
http://nitecruzr.blogspot.com/2007/06/determining-mtu-to-single-server.html

I'm not so sure that getting a Blockbuster web page with a yellow border around
the Privacy Statement indicates MTU though. That may be a Blockbuster question.

Chuck,

Thanks for joining in. There are two main symptoms so far.

Paul (the OP) seems[1] to be showing (via View Source) of IE7's
attempt to open http://www.blockbuster.co.uk/ that the HTML
may be truncated (e.g. the View Source doesn't contain an ending
/HTML> tag.)

[1] He didn't exactly prove that or tell me what line he copied down to
but that is what I assumed could be inferred by the sentence:

As you can see not much....

I gave hints for setting up Notepad to show line and column numbers
and for seeing the size of the received file so we may yet get more
specific confirmation about this.

The other point is that the source extracts Paul does show are not elements
which appear when I try that URL. That was my point about the "roundedYellow"
etc. So we don't know how that arrives or where it occurs. E.g., I suppose I could
have suggested he actually search for an </HTML> end tag instead of just go to
the bottom of the source. If there is an </HTML> end tag before that the symptom
may be something entirely different.

Therefore, assuming that that last possibility is unlikely and that the "not much"
comment was sufficient cause to think about a corrupted or truncated transmission
I decided to elicit some help on the networking side. <w> The reason I suggested
checking with the ISP instead of the Blockbuster site is because the ISP will be
closer. E.g. if the problem is occurring in an intermediate node Blockbuster
may be unlikely to want to help. Also the the ISP is what he will be paying money to... ; )

Thanks for the link.

Robert,

One discussion that's ongoing in parts of the Internet focuses on the issue of
"net neutrality", where some ISPs are rumoured to be filtering, capriciously,
specific content from various web sites, as the content passes through their
portal, on the way to computers owned by their customers.

Supposedly, the practice of changing specific content, rather than filtering it,
is a possibility. If the ISP is responsible for inserting code into this web
page, ie adding a "<div ... > ... </div>", that would be a bit more egregious
than mere "net neutrality" violation. I sincerely hope that is not the case
here.

I really don't think that this is a Windows XP issue. DSLR Forums is a general
purpose techie community, and their Networking forum would be a good place to
explore this issue.
<http://www.dslreports.com/forum/sharing>
http://www.dslreports.com/forum/sharing

Keeping an open mind, I included my semi scripted procedure for determining the
correct MTU setting, which is simple to do, and if that's the problem could set
the OPs mind at ease.

Hello. Robert. Re the page loading here is a copy of view source:
....
div class="roundedYellow"
h2><img src="/bbimages/uk/titles/BBPrivacyStatementBTsy.gif"
width="371" height="28" alt="Blockbuster Website Privacy Statement" /></h2
div class="roundedContentYellow"

As you can see not much....

Looks like you may be receiving some custom content as a subscriber then.
I don't get anything like that. E.g. no "roundedYellow" and the only instances
of the word "privacy" don't have either of the contexts shown above.

In any case the most likely explanation for this is a problem with MTU size.
You're going to have difficulty finding the correct size to use though
because all of the tests that I know of for determining it rely on ping -f -l
I think you should check with your ISP for help. Very likely this would be
an issue which other subscribers would have already had to deal with.

See this post for my previous comments on that possibility.
As I indicated there a better newsgroup for resolving it would be
one which specializes in networking for your OS.

Another thing you should try since you suspect a connectivity problem
with that site is simplifying your test case. E.g. try opening this one (661 bytes)

http://www.blockbuster.co.uk/BBImages/UK/Glossy/NewHome/StoreLocator/SearchButton.gif

and this one (4075 bytes)

http://www.blockbuster.co.uk/BBImages/UK/Glossy/NewHome/StoreLocator/BlockbusterMap.gif

Note that both of those are cacheable so in order to test if you can actually
receive them (and not just check the cache for their freshness) you should
retest both by pressing Ctrl-F5.

Something else strange I noticed in the images which could cause a
problem (especially if some page modification is happening anywhere,
e.g. the possibility that Chuck mentioned) is that there is a single pixel
image which uses https protocol.

https://switch.atdmt.com/action/repbbs_homepage_8

When I try to retrieve that using telnet 80 (i.e. http) something does
come in but it's

Content-Location: http://image.atdmt.com/images/pixel.gif

(plus a Cookie)

Hmm... now I notice that besides that Cookie I also got a Cookie from
adviva. So if you want to delete the Blockbuster Cookie you might as well
delete those two as well.

FYI the way that I use to tell if a Cookie has been accessed (not just written)
is to enter in a cmd window:

cd /d %USERPROFILE%\Cookies
and
dir/ta/od

Unfortunately that lists all the Cookies in the the directory but it lists the
last accessed ones last. So that's how I can see those three after
visting the site.

Provided Cookies were just written you could also see them in the TIF Viewer
in the Details view, when ordered by Last Accessed. I already mentioned
the keystrokes to open the TIF Viewer (Alt-T,O,Alt-S,V) but I forgot to
mention getting it into a useful view (Alt-V,D and Alt-V,I,Last Accessed)
and then Ctrl-End to scroll to the bottom...

BTW that's where you would find the "URL" view-source:http://www.blockbuster.co.uk/
which I was suggesting you could use its Properties to find out how big your
copy of the HTML is. (I.e., once you have actually done a View Source of that
non-cacheable file using Alt-V,c.) ; )

I would recommend that you look at a software product called TCP-Com
at:
http://www.taltech.com/products/tcpcom.html

TCP-Com can open a a TCP/IP port and feed any data that comes into
that port either to a physical COM port or it can create a Virtual COM
port that any other serial communication software would be able to
open and read in the data.

RE: WIN32 TCP <-> COM4 interface

Hi All,

I have a legacy product that currently listens and processes messages
from a COM port at 4800 baud. Data is incoming only, so there aren't
any acknowledgements.

Suggestions please on the easiest solution to create a TCP listening
server on an arbitrary socket. Incoming data via the TCP socket is
then copied over to the COM port.

The XP machine in question does not have COM4 fitted, so how difficult
is it to install a virtual COM4 device, with this fed with TCP data ?

Are there any commercial product that allow this ? What is involved to
write this using VC6 ?

Is there a more appropriate usenet group to pose this question ?

Many thanks,

Hello. I thought I would update.

I went to a friends house and ran through everything I had done at home and
to my surprise I got the same results, timed out etc, except that I could get
on the BB website and view source, full page and the HTML tags.
I came home and thought what to do now. typed the url into IE7 and bingo
problem resolved.
Very pleased but would really like to know what it was.
I did get in touch with BB and they said they could not help.
As for AOL not impressed with their "customer care".

So, are you implying that the screen was blank but View Source shows
that you do have an ending </HTML> tag? Were you using IE7 in both
cases?

Be aware that a missing </HTML> tag would just be the easiest to analyse
example of a cause of the more general problem of a corrupted transmission.
E.g. unless you are also considering the size of the HTML file you can't claim
that the source is available for the "full page". IE7 in particular will stop rendering
when it detects invalid HTML. IE6 used to be much looser about parsing
invalid HTML and trying to do something useful with it but that was by going
against standards, something that IE7 corrects.

Quote:

Now it sounds as if you were previously trying to open the page using a
URL saved in a Favorite? Did you compare the actual URL that the Favorite
would open versus the one that you typed? Also, be aware that modifying
Favorites is a possible "spyware" technique. E.g. before visiting the site
that the user is expecting to see a visit is made to the spyware site. Etc.

In order to get a better picture of the differences in the two results
you could try using Fiddler2 yourself. However, Fiddler is implemented
as a proxy and some sites appear to refuse to connect to clients
which are running proxies. E.g. proxies are also used to implement
ad scrapers, etc. so perhaps such sites are denying us the opportunity
to use such utilities. And in the same way it could give a spyware site
the clue to perform differently and thus try to evade detection
or at least minimize the possibility of its analysis.

The most complete, most transparent diagnostic that I am aware of
would be to use netcap to capture TCP packets and then use
Ethereal to format them and follow the HTTP streams. Even then,
in the case of onboard malware I have often wondered if it would
notice the presence of the trace and stop or alter its activities.
In that case, I have sometimes suggested that such tracing might
provide a workaround for such problem sources... ; )

Robert. the blank page only showed the source of which I posted earlier on in
the discussion, only half a dozen lines and no end html tag. Yes I was using
IE7 in both instances.
Regarding the url/favourites, I have to admit at first I was using
favourites but subsequently typed the numerical url.
I noted your comments and will look further...Paul

Hello. I thought I would update.
I went to a friends house and ran through everything I had done at home and
to my surprise I got the same results, timed out etc, except that I could get
on the BB website and view source, full page and the HTML tags.

So, are you implying that the screen was blank but View Source shows
that you do have an ending </HTML> tag? Were you using IE7 in both
cases?

Be aware that a missing </HTML> tag would just be the easiest to analyse
example of a cause of the more general problem of a corrupted transmission.
E.g. unless you are also considering the size of the HTML file you can't claim
that the source is available for the "full page". IE7 in particular will stop rendering
when it detects invalid HTML. IE6 used to be much looser about parsing
invalid HTML and trying to do something useful with it but that was by going
against standards, something that IE7 corrects.

I came home and thought what to do now. typed the url into IE7 and bingo
problem resolved.

Now it sounds as if you were previously trying to open the page using a
URL saved in a Favorite? Did you compare the actual URL that the Favorite
would open versus the one that you typed? Also, be aware that modifying
Favorites is a possible "spyware" technique. E.g. before visiting the site
that the user is expecting to see a visit is made to the spyware site. Etc.

Very pleased but would really like to know what it was.
I did get in touch with BB and they said they could not help.
As for AOL not impressed with their "customer care".
Big thank you to everybody for your input.
Bye .............Paul

In order to get a better picture of the differences in the two results
you could try using Fiddler2 yourself. However, Fiddler is implemented

Hi, i have a doubt concerning to this topic, i want to set up in the same
machine two different ip addresses for two user profiles, but on the same
network.
(when logging in with user1 to have an ip address and when logging in with
user2 to have a different ip address, same gateway, subnet mask, dns server).

I have been having http 404 error page not found on many websites

If it is really a 404 it means that you are requesting a page which does not exist.
In rare cases it might also indicate you are passing an invalid Cookie with your request.

More ominously it could be an indicator that you have spyware on board.
E.g. the spyware site intercepts your request, then sends back a fake 404.

Quote:

but usually
when I hit refresh the website comes up. However I have found one so far that
does not amazon.com. I buy regularly from them and cannot access their
website.

Neither of those symptoms appear like 404.
They look more like a problem with connectivity.
E.g. invalid lookup provided by override in HOSTS file,
invalid lookup cached in the dnscache, or invalid lookup
being provided by your ISP's DNS.

Another spyware related possibility would be having a bad DNS.
Some users have found that their DNS has been overridden
permanently by a suspect DNS address, e.g. instead of getting
one dynamically from their ISP (or vice versa, they know they
are getting deficient service from their ISP's DNS and need
to switch to a different one.)

You would have to do some kind of packet trace to check
for either possibility. In the case of malware, having a active trace
running might have even the effect of making it mysteriously stop. ; )

I was using IE6 and had this problem, upgraded to IE7 and still have
the problem.

All the more reason to suspect a networking cause.
I'll take a chance and assume that "upgraded to IE7" implies
that your OS is probably XPsp2? Cross-posting to XP networking.

Why do I need to always refresh the page or click the go back button to
get secure sites to display? Very rarely will it display correctly the
first time. It always occurs when logging in with a usersname & pw.
Ususally it just says the page can not be displayed.

Looks like a performance problem with your connection?
There is a lot of handshaking going on behind the scenes with various
protocols, especially with secure protocols. Each time more has to be done
there is a risk that a request may get lost or abandoned. Unfortunately it is
especially hard to diagnose problems with secure protocols (e.g. using a
protocol analyser) because of the Man-in-the-middle problem. Nevertheless
you could use Fiddler2 to at least try to gain some insight on your symptoms.

Sometimes the page still will display with red X boxes.

I tried reinstalling, shutting off phishing filter nothing works, and I'm
tired of it.

I think you should be looking at the other security settings in that section.
(Options, Advanced tab, Security section) In particular uncheck Use SSL 2.0
if you have it checked but check the other two security standards under that one.

Good luck
