I have a client running a small network. There are 2 Windows 2000 Computers, and 4 XP Pro Computers, and then 2-3 laptops that come and go.

The 4 XP Pro Computers are M, D, C, & H. All of them have 2 shared folders that are mapped as drives to the other computers. The shares are setup with permissions as not all computers on the network are privy to the same info. Each Computer has all 4 users setup on them.

C often does not seem to allow the other computers to connect, even though they can still connect to each other and C can still connect to them. When D couldn't conenct to C today, they shutdown both computers and then booted them back up... the same. They then rebooted one and tested and then the other and tested... they waited awhile and tested again... same. When I came in, I first tried to connect to C from H, it prompted for login info, which I gave. Then it worked.

I find the whole thing to be very bizarre. I had wondered if that Network Cache could be part of the issue, but I'm not sure.
