XP Pro/2K AD Network Shares Disappear

I have a problem with Windows XP machines connecting to a
2K server. Currently, I have two different clients, both
running Windows XP Pro machines on Active Directory
Integrated W2K Domains. Overnight, the XP boxes seem to
lose connection with the server. They still have internet
access, DNS resolution is fine, but mapped drives and
shared printers disappear. This also doesn't happen on all
of the machines at the same time. Generally, one or two
out of three will do this every night. Let me know if you
have anything for me! Thanks again!!
