Drive Mappings Dropping Out

This is concerning Windows 2000 computers running behind a Dell PowerEdge 4600 server running Windows 2003 Server. The server is acting as a domain controller, Exchange Server, print server and file server. Print duty is very light - most of the users also have their own desktop printers.

When we connect to a mapped drive after a short period of unuse, we get an error message. Repeat attempts at accessing the drives eventually gives the user access with no re-login required.

I just discovered that this failure may not be so random after all. While attempting to transfer about 80,000 text files over, I would receive an error message before the task conpleted. Then I would look & 7 - 10K of the files would be transferred and attempting to acess the mapped drive netted the same error.

The message states that the device is unavailable and that the device name is already in use.

Did you have a WIN server setup?
Did you have the same problem with all other Win 2000 client?
Did you choose 'NetBios over TCP/IP' option in your NIC Advance Property, WIN tab on both client and server?
Problem happened with the same user or any users?

I don't have WIn Server setup.
It happens with all clients - one is running XP Pro.
I need to look at the NetBios option.

You need to set a WIN server in mix-mode environment to solve this problem. For now, net bios set up is important to resolve the name.

I looked and don't even see the NetBios over TCP setting that I used to see on older machines. Doesn't DNS take the place of NetBios on newer shemas?

Thanks, Tom

Correction:
In the link of my last post, you choose the option "Netbios over TCP/IP" instead of disable netbios as the instruction does. Also, you can skip the last step as it is for disable netbios only.
Make sure you set it on both client/server
