Losing Domain Connections

[cherisc]

Hello,

I am running Windows XP Pro on a Windows 2000 Domain. When I log into the domain at first, things run fairly smoothly. After time, whether my computer is sitting idle or I am working, I seem to loose connections to Domain Resources. I cannot access network printers or my network drives that are housed on the domain controller/file server, and my computer becomes extremely slow at opening anything. Here are some errors that I get:

When I try to access a Network drive, I get the following Windows Explorer Error:
U:\ is not accessible.
The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.

Around the same time that this is happening, I get the following errors in event viewer:

Source: Userenv
Event ID: 1054
User: NT AUTHORITY/SYSTEM
Windows cannot obtain the domain controller name for your computer network. (The specified name either does not exist or could not be contacted.) Group policy processing aborted.

Source: AutoEnrollment
Event ID: 15
User: N/A
Automatic Certificate Enrollment for XXXXXX\myusername failed to contact the active directory. The specified domain either does not exist or could not be contacted. Enrollment will not be performed.

Simply logging off then back on corrects this problem. I found the following microsoft article, but it did not help:

Any suggestions would be great. Thanks.

Are the DNS settings on the station pointing to your local AD DNS server not your ISP's?

I have seen loss of Network resources when the PC Clock is more than 5 mins out of synch with its DC. Your logon script maybe set to synch the time at login - but then the PC clock looses / gains time.

Is the time Zone set correctly on the PC?

Any W32Time events in the Event log?
