Hi,

I have a difficult to solve problems that I havent been able to get help on previously so im going to take another try at it.

We have a single windows 2003 domain. We have two DC's at headquarters. All of our machines are virtualized on ESX. All clients are windows XP Sp1 and Sp2. Each runs symantec corporate antivirus. Some people have been affected by this and after a few months the problem goes away, others always have this problem every day and must reboot to gain access again.

The problem: All times CST.

At around 3 to 5 pm, users will be printing, using email, saving documents on the server etc. When suddenly they receive theses errors:

Client one - in picture error #1 - "Windows Needs your current credentials to ensure network connectivity"
Client Two - errors # 2- Multiple errors see screenshots

At that time they will not be able to print, exchange goes from connected to offline, and they cannot access any files shares even on NAS devices that authenticate through AD. The only way we have found to fix this is to reboot the computer.

Things I have checked:

1. Time on each machine is almost exactly the same as the server and other workstations that are  not having this problem.
2. Logon hours, etc in AD are set to allow all the time.
3. Network cards are not set to go into powersave.
4. In windows and the bios machines are set to always on and no powersaving features are enabled.

This one has me stumped, help!
