Symptoms

Consider the following scenario:

  1. You start a Remote Desktop session to a Remote Desktop server from a computer that is running Windows Server 2008 R2 or Windows 7.

  2. You remotely control another Remote Desktop session. This is known as "shadowing."

  3. You run an application that displays bitmaps in the remotely controlled Remote Desktop session. For example, you open a Control Panel item.

In this scenario, the remote control session fails, and you receive the following error message:

"Because of a protocol error, this session will be disconnected. Please try connecting to the remote computer again."

Cause

The issue occurs because Remote Desktop Connection (RDC) 7.0 does not handle the monochrome bitmap pattern brush correctly.
