Remote Desktop Services Session Shadowing Problems

Good Afternoon everyone

I have a clients Server 2008 R2 Enterprise server the is being used in a small medical clinic. This server is running an EMR software that requires terminal services, therefor we have Remote Desktop Services role installed so that the 8 users in the office can login from their client machines.

This has been done with this software for years using server 2003, and for administering the users while they are logged in we would simply login to the administrator account using RDP, then using session shadowing we could help out users as needed.

With this particular install of 2008 we are not able to do the same, we get "the requested session denied remote control" error when trying to shadow.

I have confirmed that the user is getting the prompt to accept the connection, and they are hitting yes. From here my screen goes black for a few seconds, then i am greeted by the above message.

I notice the event 26 in the system log, stating that a application pop-up has occurred, after this there is nothing related in the system log.

In the security log at the same time there is an Audit failure (error 4625) for the admin account i am using.

I have ensured that the GPO settings for the "Allow log on through Remote Desktop Services" has the correct groups in it. And the users themselves are having no issues.

Any ideas on why i am not able to use this feature?

FIPS encryption settings on the server maybe don't match the PC you're using to RDP as Admin?

Do you have the server set to allow all RDP connections or is it set to use NLA and you don't have the latest client nor are authenticated?
