Symptoms

“Shadow failed. Error code 7050” (Error 7050 – The requested session cannot be controlled remotely. This may be because the session is disconnected or does not currently have a user logged on. )

Cause 1

This error was observed when attempting to shadow users across different servers.

Users can shadow using the following methods:

• Citrix Management Console if the user resides on the same server from which the shadow request originates

• Citrix Server Administration

• Shadow Taskbar

• Command line using the command Cshadow.exe

Resolution 1

This issue was first resolved with MetaFrame XP 1.0 Service Pack 1.

Cause 2

The option for shadowing an RDP session from the Management Console shouldn’t be available. Normally the option to shadow an RDP session is grayed out, but after installing Service Pack 4 for MetaFrame XP it is made available.

Resolution 2

Citrix is working on a post Service Pack 4 hotfix to gray out the option.

Cause 3

Shadowing from the Management Console over RDP failed. The issue occurred because of a code error.

Resolution 3

Apply MPSE300W2K3R04 or its equivalent.

If this hotfix is not applied and one is unable to use an ICA session or the Management Console from a remote workstation use a console RDP session (mstsc /console)
