Windows Server 2003 R2 gray screen after several minutes of network access?

Windows Server 2003 R2 gray screen

Server is a Citrix virtualized environment 6.1, Windows Server 2003 R2:


We start the server after a few minutes of use, lost access via remote connection, and the network share is lost.

we have to force the reboot of the VM after that access back normally.

Does this happen to all or just one user, the administrator?  4GB and 30 users means that to avoid continous paging/swapping memory in and out, each user can not have more than  136MB of which is not really accurate,  The OS consumes ~1GB and leaves 3 for the user meaning each can not exceed 100MB.  Based on your question, I gather after a reboot it probably runs without issues for a week or so?
Does your terminal server GPO include forced logoff i.e. a session is left on the TS running while the user disconnected? Do you have a limiting mechanism to prevent the same user from having two sessions (user disconnects because of loss of network connection, while the session on the TS is still reflecting as active? In this case the user would have to manually switch sessions and then terminate the old one since one can not resume an active session during a connection.)?

Look at the amount of memory space a user needs tasklist /fi "username eq <username>"
What applications are in use?
Oh, If it is a win2k3 presumably standard or 32bit (not enterprise), your 4GB is the max.

Looking at maintaining the sessions of only active users may help.
Not sure why you would have a share on the TS server.
Is the system configured as an application server? properties of my computer, advanced, performance settings, advanced, programs is the selected options in both cases?
Adding additional space for paging/cache file. could also improve performance.  You currently have 2GB?
