Intermittent Network Connection Problems after XP

[Guest]

I have two new Pentium 4 computers that came with XP. I have several other
Pentium 3 computers that I just upgraded to XP. The computers are on a
peer-to-peer network that worked just fine for many years. One computer is
used as a server to store files in a central location and all other computers
have file sharing turned off.

After upgrading to XP, I am now experiencing interoffice network
connectivity problems. The connectivity problems are intermittent and random
between the computers. I also added a printer router to one of the router
branches. When the problem occurs, the connection to the server and all
other computers is lost and is not easily re-established.

In some instances, the "Repair Network Connection" works. In some instances
the "Network Setup Wizard" works. Sometimes the computer needs to be logged
off and on. Other times the computer needs to be rebooted. Sometimes the
connection is re-established quickly, and other times it takes a couple of
minutes.

Further, it seem that after a connection is re-established, and whtn the
computer is not actively used for 15-30 minutes, then the connection is lost
again. The problem has that appearance that the server/network is looking
for activity, and if it is not detected, it breaks the network connection.

The error message reads, "Server is not accessible. You might not have
permission to use this network resource. Contact the network administrator
to see if you have access permissions. --- The list of servers for this
workgroup is currently not available."

Throughout the network problems, the Internet works well.

Thanks in advance for any suggestions.

i am having a similar problem recently

periodically IE loses the server connection
often just after bringing laptop out of sleep mode

sometimes it happens when i try to open a new browser window
it wont connect but the old window still connects fine

however NetTransport is happily downloading in the background !

Firefox browser will not connect (same as IE)

repair connection has nor effect

only solution is to reboot

running win xp sp2 fully updated
connect by wireless LAN
sony laptop VGN-S3XP
use zonealarm but not windows firewall
(but disabling makes no difference once problem encountered)
virus checked with AVG Spybot AdAware

any ideas anyone - how can i even start to diagnose ????

Ray,

Intermittent connectivity problems, with the "...not accessible...no
permissions...list of servers not available", is normal for a browser conflict.
Your workarounds, like restarting, and / or waiting, are normal too.

Please ensure that you do NOT have physical connectivity issues, nor firewall
issues.

Diagnose browser problems by running browstat on several computers, and
comparing the output. Please read this article for instructions.

Your symptoms, knowing what Ray's suggest, are not really the same. Please
start a new thread, with unique and descriptive Subject, so all here can find
your thread and diagnose your problem more effectively.

Chuck,

Thank you for your help. I am embarrassed to admit that I was networking
too many XP Home versions together... I didn't realize that there was a
limitation. After upgrading all computers to XP PRO, I'm back in business.

I hope that you are on MicroSoft's payroll for all the help that you are on
this newsgroup.

Thanks again.
Ray

Ray,

I'm a volunteer, like many, but I thank you for your feedback. And thank you
for updating this thread, and providing one more item to add to my
troubleshooting guide.

Well, that's why it's a blog. Subject to constant revision.
