Hi Suresh,

What is the OS in the system that you are trying to connect to?
Is the problem with particular user account only or with all user accounts?

Try disabling use of bitmap caching

Hi Suresh,

This issue also occurs if HKEY_USERS.Default\Control Panel\Colors
subkey in the registry is set to "0 0 0:" (i.e. black)

All the users are facing the same issue.When I checked the tasklist there are many process names csrss.exe and winlogon.exe which is occupying much memory .

Hi Suresh,

>> If so how to stop the process of this machine from remotely.
If the remote OS is Windows XP/VISTA then you can make use of
tasklist/taskkill commands.

Thanks Murali ,The destination machine is Win Server 2003 (VM box) and I tried killing the process winlogon which took more CPU using taskkill but unfortunately I was unable to kill those process as this is a critical process .Any how we have rebooted the box now the problem is resolved .But still I am expecting some comments from HP forum friends to solve this problem without reboot

Hi,

A password-protected screen saver can be the cause of this problem.

Try running Ctrl+Alt+End next time it happens.

If that's not the problem, alternatively you can run either the following:
quser /server:ServerName
qwinsta /server:ServerName

Once you know the ID of the current RDP session, you could logoff or reset that particular session by running either of the following commands here below:

RESET winsta %type_sesion_ID_here% /v /server:ServerName

LOGOFF %sessionID% /v /server:ServerName

You can run any of these from a workstation. All you will need is credentials for that Win 2K3 you're having issues with.

Hope it helps.
