XP workstaion can’t create domain files

I have a remote client on my VPN LAN that is a member of the domain. However, when she tries to create a file on our W2K fileserver she “can” see the files she creates, but the rest of the company cannot see them. Including the administrator account on the domain server. I have tried everything I can think of, including (against my better judgment) updating her to XP pro SP2. It doesn’t even show me that a directory containing a file she creates has any data in it at all (through properties).

through RDC I can log into her machine and see the files that were created, but If I go back in the server *poof* like Houdini

I have seen some wierd microsoft problems in my day, but this is completely off the map…

Anybody seen this Before?
