Hi and Thank's for your replies!

There are no "Funky":-) apps on the server.... Only MSOffice 2003, Adobe Reader 7.0, And MF PS 4.0.
There are at the most 5 concurrent users on the server...

I am using Load Balancing on all applications in the farm, and the users profile is copied from the Domain Controller to the profiles directory on the server that runs the application.... Is it possible that there could be a problem if the user starts an application on "server 1" and then starts another application at almost the same time on "server 2"??

Anyway... here are the errors from the event log on server2

All Users have the same problem...

I have made hidden share called "\\SERVERNAME\Profiles$\" and created a directory for every user here.

The permissions on the share are set to "Change" and "Read" for all the users... The security rights on the shared folder is:
All users have Modify, Read & Execute, List Folder Contents, Read, Write.

On the subfolder that contains the profile the security permissions are as follows:
The user have Modify, Read & Execute, List Folder Contents, Read, Write.

Available VM seems ok... Hmmm... (I feel stupid now but...) where can i see the registry size in W2k3 SP2? It used to be at the same place where the Paging File was set.... But not in this ver...

I dont think there is a corrupted profile... When the error first starts with one user... every user gets the same error...
