XP workstation keeps dropping SBS 2003 server connection

I support a small SBS 2003 Premium network where one computer running XP Pro SP3 keeps dropping it's connection to the server.

This is simply rectified by a restart (initially logoff/logon resolved it), but it is becoming frustrating for the user.

Can't see anything obvious in event viewer.

Any ideas?

agree with cris - what happens when the network drops?  Are you unable to ping the server?  NIC seems like the most probable culprit.

Thanks guys, but I don't think it is as the Internet remains accessible all the time.

only one workstation?   once a day or more often?
I'd still replace the nic...protocols to server more complex than to web
Also check nic properties...power management enabled?

Next time, disable the nic then re-enable  instead of re-booting... if that fixes it its NIC related ...try updating driver

Thanks Cris I'll check out re-enabling it when it happens next, Yes, only one w/s, couple of times a day.

It will probably show enabled already so disable , then reenable

That did the trick, apologies for doubting it.

Now just a question of finding an old box that contains loads of RTL8139 NICs, many still boxed. I'll try one on Monday and if it works for 24hrs I will close the thread and award the points.

New NIC did the trick for 36 hrs then back to dropping the network connection to the server.

Does this issue persist no matter what profile is on the computer?  Could be something in the user's profile.  When you say it's dropping the connection to the SBS box, is it dropping the Exchange connection or mapped drives?  My next step would be to recreate the user's profile and see if it continues.

So do you have to reboot or can you disable and re-enable and it comes back to life?

Before the last bout of trouble a disable/enable would work fine, but now only a full reboot will do.

Does this issue persist no matter what profile is on the computer?  Could be something in the
 user's profile.  When you say it's dropping the connection to the SBS box, is it dropping the Exchange connection or mapped drives?  My next step would be to recreate the user's profile and see if it continues.


I have only tried the one profile. The user has three main network connections on his desktop.

1. Shortcut to Shared folder on server.
2. Shortcut to Access Company database.
3. Shortcut to Access Leads database.

When the connection is "lost" the Shared folder opens (no error msg) but is completely empty and the 2 databases cannot be found.

Would I be better off removing the PC from the server and run connectcomputer again?

Thanks,

Mike

I'm leaving the office now so if it's two hours before I reply, I'm just in traffic.

On the server are you seeing anything in the event logs regarding this workstation?

I think I have come across the answer accidentally. I was unable to save an file, getting the disk is full msg. I knew 100GB plus was available, but failed to check the quotas. Two PCs including the problem one was on 990MB and the the problem one was on 999.1MB on default 1GB quota.

I've set both to 5GB. Surprised I didn't receive any warnings.
