We have a handful of Windows 98SE machines in remote locations that map a drive back to our Windows 2000 Advanced Server box. We can do a "find computer" by IP address or use "net use p: \\IP Address\Share Name" to get to the server. However, after a period of time (the length of time varies from machine to machine) the drive letter is no longer available. Searching for the computer no longer returns any results and "net use" does not work. The only solution seems to be to restart the Windows 98 clients. After a reboot, we are able to get the drive letter restored using either of the above methods. Any ideas? Thanks for your help.
