XP dropping off LAN 1

[Guntha]

I have a couple XP Pro SP1 PC's that are dropping of fmy LAN and I dont know why? All my WIN2K Pro PC's are fine but the only 3 PC running XP fall off the LAN and give an error message that says "Local Device Name Already Exists."
It seems like the PC's are fine in the morning but seem to drop their LAN connection for some strange reason and when you go to use a mapped drive after an hour or so of no Network usage the network connection tries to restablish itself but the PC's presense is still on the LAN? This is kind of upsetting to the user Can anyone help????

Check the power management settings for the network cards and make sure that the system isn't shutting them down.

go into Device Manager and then check the properties of your network card, under power managemnet there is an option for "allow windows to turn off this device to save power" ---------------

I'm having the same problem with a clients machine. When a drive is mapped we can open a file from the mapped drive for say 20 min then we get an error that says the drive is already is use. When we go to delete drive map sometimes there would be a second instance of the drive which isn't happening every time. It's hit or miss. One thing if for certain it is doing this on the users acount and the administrator account and once it happens the computer can't browse the network till the machine is restarted. We created a new user space and are having the same problem. I've tried the winsock fix utility which seemed to increase the time till it stopped working. Any help would be appreciated.

Particularly for workgroup settings, you need to adjust the default timeout for both client-side and share-side connections.

See:

http://support.microsoft.com/defaul...port/kb/articles/q138/3/65.asp&NoWebContent=1

The sharing server will have an autodisconnect for an "inactive" connection; and the net "using" workstation will similarly time out these connections.

Well tht is getting me nowhere. This is server side anyhow.

I have 4 computers on workgroup including a few clones of this machine and they are all fine.

Are you using Fast User Switching to test this?

 

[fingaz]

Fast switching.

I have tried with it both ways. Either way, or whatever user login, it will not browse the workgroup or keepa a mapped drive connected.
