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.
