The task you are trying to do can't be completed because Remote Desktop Services is currently busy. Please try again in a few minutes. Other users should still be able to log on.

Cause

This issue occurs because of a deadlock situation that occurs between the Csrss.exe process and some applications (for example, Microsoft Excel or Microsoft Visio).
