Hi,
I have 2 major problems.
1. Win2000 Termianl Service clients always face "Disk or
Network Error" problem when open an Access XP file.

2. The in-house application which is developed by VB 6 may
close unexpectedly for opening some child forms.

Other applications seem to be alright and these 2 problems
can be solved if I restart the Win2000 server.

Please give me a hand. Thanks.

Which SP are you running on the server? One of the causes for the
"Disk or Network error" is supposed to be fixed in SP3. Check:

272582 - Windows 2000 Terminal Services Incorrectly Closes Files on
Remote Shares
http://support.microsoft.com/?kbid=272582

But there are more situations in which you can get this error
message. There's a pre-SP5 hotfix as well:

818528 - Problems When More Than One User Accesses the Same File
Through Terminal Services
http://support.microsoft.com/?kbid=818528


Can't help you with your VB program, except with a general advise:
download FileMon and RegMon from http://www.sysinternals.com/.
Run them as administrator, start a TS session as a normal user and
try to run the application.

FileMon and RegMon will show you what is going on and maybe give you
an insight in why the program dies.
