provider is Netzero via Verizon. When I ping another computer on
the home network, the resulting FQDN name I see is
pcname.dns.netzero.com. The 'pcname' is the name of I have for my
PC which is different for each one. The "dns.netzero.com" is made
up, but the router gets configured by the ISP to be the DNS server
for NetZero, lets say for discussion purposes 'dns.netzero.com'.
What is happening is that the pcname is concatenated with the dns
server name and the resulting IP address I see is the address of
the DNS server not the local subnet address of 192.168.x.x which
is DHCP'd by the router. Thus, the other PC's queried/accessed by
using the "PCname" won't respond as being there since the IP
address is the dns server address.

Yes. It works this way. "Ping" is a TCP/IP application, not a NetBT
application. When supplied with a non-qualified domain name (one
without dots), TCP appends domain names according to how TCP/IP was
configured. In your case, if you go to:
Network Control Panel -> Double-click connection -> Properties ->
double-click "Internet Protocol" in window -> Advanced -> Dns Tab ->
You probably have "Append primary and connection-specific DNS Suffixes
checked. The suffixes you are seeing are provided by your ISP as part
of the DHCP configuration. This is actually needed, for example, when
your ISP tells you to configure your Email Client Server with simply
"mail", knowing that the appropriate suffix will automatically be
appended depending on what part of the country you are in.
If the resulting DNS name does not resolve, then Windows will fall back
on Windows Networking to resolve the name. If it does resolve, then
you have an IP address of a computer that you don't want.
| Quote: | However, if I ping by the 192.168.x.x address, that address is
also valid and will respond with a reply along with now being able
to access a PC on the local subnet.
|
Yes. In this case, you've eliminated the middleman name-resolving step
and called out the address manually.
| Quote: | I have Netbios enabled and the ipconfig /all shows the correct
subnet address DHCP'd assigned as 192.168.x.x for a particular PC.
I can also do filesharing too. The ipconfig also shows "broadcast"
for each one via the registry entry of "DHCPNODETYPE" being 0x1. I
don't think the registry value should be mixed or hybrid since I
don't use a Wins server nor is it configured.
|
If you configure a WINS server, the type will default to Hybrid. If you
don't, it will probably default to "Broadcast". Both Hybrid and
Broadcast will do broadcasts if the WINS server does not resolve.
| Quote: | However, Ipconfig does show that the Wins proxy is enabled as
'yes'. I don't see that there is a checkbox or a way to enable the
Wins Proxy in the network card properties.
|
Since you don't seem to be using a WINS server, the proxy function will
not do anything. How to enable/disable the proxy function is shown
here:
<http://www.jsifaq.com/SF/Tips/Tip.aspx?id=5558>
| Quote: | Moreover, the router domain name is a blank along with the domain
name that is entered as part of network setup wizard since I use
the Workgroup setting. Also, the registry for "domain" is empty
too. More information: all IP address' are selected to be auto
from the DHCP router, all DNS' are auto,
|
Don't confuse a TCP/IP domain name (the one provided by your ISP that
get appended to a non-FQDN) with the Domain/Workgroup names that are
associated with NetBT (Windows Networking) protocol. Two different
things.
| Quote: | when I ping the pcname of the PC I'm currently logged/using it

192.168.x.x address.

Your PC name is Cached locally and apparently is resolved before an
external DNS query occurs.

local subnet pcname?
|
Answered above. (It is configured that way)
| Quote: | One possibility may be that a PC was setup during network setup
wizard to connect directly to the internet vs. the others to
connect to a LAN and then to the internet? Trying to track down
which one if at all this was done to. They should all be setup to

connecting to the router via wireless and some using a CAT5 cable
to the router. Hmmmmm????
|
Gibberish. When a wireless router is handling network traffic, all
traffic, whether wireless or wired, gets around the same way. When
communicating with a device on the same network, the traffic goes
directly to that device, wireless or wired as is appropriate. All
internet traffic is sent through the Router's WAN port.
I don't know what your problem is... Everything is working as it
should. You do seem to be confusing normal TCP/IP protocols with
Windows Networking's NetBT protocols (NetBT = NetBIOS-over-TCP/IP).
Windows Networking has different name resolving techniques than
straight TCP/IP (Using Master Browsers and "LMHosts" file instead of
DNS Servers and "Hosts" file) although when desperate, they tend to
query each other's tables.
A good place to look to resolve this confusion is:
"Domain Browsing with TCP/IP and LMHOSTS Files"

Well, after trying a few things, which included turning off all the

the wireless laptop running Pro. However I'm still having issues connecting

Any further suggestions? |

On the computer, look at the DNS page of the TCP/IP properties for the LAN
connection. Chances are you have a 'DNS suffix' set, and possibly also a
'DNS search order.' On an internal LAN these items should be blank UNLESS you
own a domain for internal use, such as a large company might have.
Having the name of a domain which you do not own -and which is external to
your LAN- in here will cause trouble with connections between local
computers.
Before removing the suffix entry, you may wish to check the server settings
in your mail client, as these may be relying on the domain being appended to
a short-form name. If so, change the mailserver names accordingly. |

Sounds like your network is working, since you can (I assume) access the
tower's files from your laptop and can even print on the laptop's printer
from your tower - right?
Now you need to set up the laptop's shared folders so that the tower
has access to them. How to do so depends on whether your two PCs are
using XP PRO's simple or complex (M$ calls it advanced) filesystem.
For testing purposes, create a C:\TempTest folder on each PC, and
check the box for ShareThisFolderOnTheNetwork: from Explorer, r.click
on that folder then click on Sharing. Next, create a net.mapped drive
on the tower to that folder on the laptop, and a net.mapped drive on
the laptop to that folder on the tower. Next, create accounts on each
PC with the same credentials (e.g., user=SAM, PW=SPADE) and make sure
that each SAM can access that folder on its own PC. If that folder on
the tower can be accessed from SAM on the laptop and if that folder on
the laptop can be accessed from SAM on the tower, then you're done; if not,
capture the exact error message and supply that along with the filesystem
types.

perfectly for other browsers but not for the members using IE.
Any idea on why and how to fix the issue?? I personally was using the latest
version of IE but not sure if others were using older versions - but its
everyone using IE that is having the trouble.
website that works with IE- www.julieandrewsonline.com
forum that stopped working with IE yesterday
http://www.julieandrewsonline.com/forum/index.php
|
The day you reported it I couldn't open that page either.
Fiddler2 indicated that it had a problem decompressing the response
<transcription>
<Title> Fiddler: UnGZip failed </Title>
<text>
The content could not be decompressed.
The calculated checksum differs from the stored checksum.
</text>
</transcription>
Somehow in spite of that IE managed to make something of the response
because I also saw a request and response for:
http://www.julieandrewsonline.com/forum/Themes/default/script.js?fin11
Some scripting is also present in
http://www.julieandrewsonline.com/forum/index.php
which gets cached in the TIF and can be dragged to a Notepad window.
When I did that I could see a problem--probably the same thing that Fiddler
was trying to point out: the source file was truncated, so (for example)
there was no ending </html> tag, so there was no HTML rendered,
so IE put up its ambiguous error message: Internet Explorer cannot display web page.
I also found the location and precise length of the cached page using a cmd window
(starting from the TIF's Content.IE5 subdirectory) with this command pipeline:
dir index* /s | findstr "Directory 2007-12-23"
E.g. then that procedure only found a file having length 20,153
Today (when it's working)
dir index* /s | findstr "Directory 2007-12-27"
has found a file having length 30,232
So probably there was some kind of truncation happening when we were
having a problem.
If there had still been a problem today I was going to try changing my MTU size.
E.g. I had noted that the maximum buffer size that ping could send seemed
to be 1424:
<cmd_output>
F:\>ping -n 1 -f -l 1425 www.julieandrewsonline.com
Pinging premium9.geo.yahoo7.akadns.net [216.39.58.157] with 1425 bytes of data:
Packet needs to be fragmented but DF set.
F:\>ping -n 1 -f -l 1424 www.julieandrewsonline.com
Pinging premium9.geo.yahoo7.akadns.net [216.39.58.157] with 1424 bytes of data:
Reply from 216.39.58.157: bytes=1424 time=62ms TTL=53
</cmd_output>
I think that 1424 is smaller than I would expect for my network interface with PPPoE.
E.g. this article implies that I might expect the maximum to be 1452 = 1480 - 28
<title>How to change the PPPoE MTU size in Windows XP</title>
http://support.microsoft.com/kb/283165
<quotes>
The default and maximum PPPoE MTU size is 1,480 bytes.
Therefore, if the MTU size is set to 1460 (decimal), the max value of NUM
in the following command line can be 1432:
ping IP_address -f -l NUM
</quotes>
I.e. I'm inferring a second (unstated) minimum size of 28 (1460-1432)
for (I guess) some headers needed to do the ping.
Fortunately other articles from the same web search makes these details moot:
(Live Search for
MTU XP site:support.microsoft.com
)
<title>Diagnoses and treatment of black hole routers</title>
http://support.microsoft.com/kb/159211/
says the preferred treatment is
<quote>
Enable PMTU Black Hole Detection on Windows hosts that will be
communicating over a wide area connection, as documented
in Microsoft Knowledge Base article 136970
(http://support.microsoft.com/kb/136970/EN-US/).
</quote>
The article referred to was written for NT 3.5 and has not been
updated to refer to any later versions of NTx (such as XP)!
Nevertheless, there is information in there which has enabled me
to see that I have a feature called PMTU Black Hole Detection
enabled:
<quote>
HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\tcpip\parameters
\EnablePMTUBHDetect (REG_DWORD, 0=disabled, 1=enabled)
</quote>
Specifically my EnablePMTUBHDetect value is set to 1.
My guess is that when requests for the site were failing
there would have been something along the path which
was making this Black Hole Detection mechanism fail
and then because the default MTU maximum would be
too big the fragmentation problem would be occurring
and data would be lost. I'm not sure what good changing
the MTU size on the client side would do anyway because
the big packets would all be originating from the server.
In any case experiments with actually changing the MTU size
can wait. (Whew! <w>)
BTW I'm cross-posting this reply to XP Networking
in case anyone there can comment further on these details,
especially the apparent discrepancy that I'm seeing
regarding the PPPoE fragmentation point, as I see that
1424 maximum on all other sites too.

Hi
May be this can Help, http://www.ezlan.net/wzc.html
The Extreme G mode is Not a recognized standard Mode, may be the D-Link
people know that some thing is wrong with this device and it is Not fully
compatible with Windows Wireless Zero Configuration (WZC).
So you try the D-Link manager and WZC, and see which one works better for
you.
Just make sure that they are Not working at the same tome.

Also look at the I/O counters. You may have to use View, Select Columns...
to add the necessary statistics.
You can also run a netstat -sp TCP 5 loop in a cmd window for another clue
about what connections are active and how much of that I/O activity could be
associated with networking. netstat -s 5 is a completely different loop
(e.g. no connections get shown and so much detail gets shown each time
that it is hard to correlate); so rather than doing that if I was also interested
in UDP activity I would start netstat -asp UDP 5 in another cmd window.
Those are diagnostics any user could try. Others may have better tools to suggest.
SysInternals used to have one called tdimon which I think gave the sort of
statistical detail you want but AFAICS it is not distributed by Microsoft
http://technet.microsoft.com/en-us/sysinternals/677683af-3f5e-42ea-8116-9c92acd2c271.aspx
E.g. I don't think that tcpview has the required statistics.

chkdsk does that checking. It would depend on the nature of the error

Take a look at your router. You may find that there are useful diagnostics
in it which you could check via a local connection (at least when only one
iexplore.exe task is in this hung state.)
Or you could try generating a Networking Diagnostics report and comparing
it with a normal report. I would try using all options *except* the ping connectivity
tests. Run... netsh diag gui is one way to start it.
IMO this is yet another example of how deficient XP is in terms of networking
diagnostics for end users. I haven't figured out what is best to use for these
circumstances either. One tool that I haven't looked at yet is perfmon.
E.g. we might be able to construct a relevant report with it that is easier
to check and assess than any of the other tools I have mentioned.
BTW I think that XP Networking is a more appropriate newsgroup
for this discussion so I am cross-posting there.
Good luck

Thanks for the comprehensive reply and for cross posting to the right user
group. I will work my way through this stuff and let you know (might take me
a while - I'm sort of half competent. I used to design very large IDMS
databases on mainframes but it is not quite the same thing).

I have this weird problem my ISP can't seem to help with. I get periods (it
seemed initially to be in the evening but is now at all times of day) of
intermittent poor internet response. Intermittent means that IE (and other
browsers - so don't think it is an IE problem really) stalls for maybe 2 - 3
minutes. The little whirring connection icon on the address bar keeps going
round and it says connecting. (Except sometimes I just get an hour glass and
sometimes I get nothing at all and the whole PC locks.
"the whole PC" or just the IE task? If you can't even move your mouse pointer
or press Ctrl-Alt-Delete to bring up Task Manager you have a problem in a
driver. E.g. looping in an non-interruptible routine.
It always comes back
with the requested web page in the end. It never times out. This suggests
that connecting is the problem not the web page. Also this is happening as
much trying to access Google as even obscure web pages. I can get this delay
several times in a row then suddenly a page request will zoom through as
normal. This can happen several times then the delayed responses return. As
you can imagine this is pretty maddening.
When this happens I have opened the task manager and looked at the processes
screen. CPU is rarely over a few % and often the processor shows 99% idle

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.

One other strange thing is that on my laptop I have AOL 9 and if I use that
to access the site quite often the page will load but obviosly within their
brower and software.
I really appreciate everybod's help as this is new ground for me but I am
learning Fast. Thank you Robert.

I for the past week have not been able to access www. block buster.co.uk.
....
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.)
