Computer name already in use?

By nsteere ·
Hi,

Win 98SE client, Win NT 4.0 Servers

My client is getting at logon:

("Microsoft Networking"
"The following error occurred while loading protocol number 1" (TCP/IP)
"Error 38: The Computer neme you specified is already in use on the network.")

Notes:

1. This happens only to this one 98 client.
2. I have fixed it by re-naming her computer but it always pops back up again sooner or later.
3. It was stable for three months. Now it is happening again.

Any Ideas?

This could be generated by a MAC address, but it's hard to say what could be causing this.

If she gets it again, I would certainly get the machine name, power the machine off, and then attempt to either tracert or ping the machine from a different computer, just to see if there is indeed another machine like that on the network.

In all actuality, I suspect you may just have a bad NIC and it just needs to be replaced, but I would certainly try to reload the drivers for it before doing so.

Microsoft KB, Article Q192534 describes this problem and gives the solution.
Too long to explain here

...If you do not receive the error message, one of the following hardware problems may exist:

This happen when you have 2 NIC card in 1 system and both Nics are connected to a hub.
