We have Windows Server 2008 R2 that works as a Remote Desktop host. From there, users again have to connect to another RD host using RemoteApp. Suddenly, mstsc.exe of RemoteApp connection started to use 25% of CPU (100% of one of the cores), causing freezes.
How do we analyze/fix this? Please help.
This problem might be caused by a device driver that misbehaves, either because it cannot communicate with its device and tries it repeatedly, or for other reasons.
The best advice is to reduce the number of shared devices until the problem disappears in order to locate the problematic device.
In the case of the poster, it was apparently a printer that once existed but was still being shared, which had to be completely removed and uninstalled.
