We are running RDS on a Server 2008 R2 ENT SP1 VM. We are encountering an odd issue. The usernames of individuals is not displayed in Task Manager. The process of the user is shown but not their username (please see attached screenshot). My administrator account does show up. When I add domain users to the local admin group then all the names are seen. How can I have these individuals show up but not have admin right?

What is the configuration of your RDS related services?  On a Test RDS Server running as a VM with Windows Server 2008 R2 Standard SP1Capture.JPGI can see the users in task manager with the services for RDS configured as follows:Capture.JPG-saige-

As a test I created a limited user that is only a member of the Users group.  Task manager for that user shows as:Capture.JPGBut logged in with my administrative user I can see the LimitedUser in the task list:Capture.JPG-saige-

This happens when the Remote Desktop Services service isn't started. Go into Control Panel > Administrative Tools > open Services > verify that Remote Desktop Services is started. If it's stopped, right click on it and start it.

Some additional details: My RDS system is part of a farm. Users hit the gateway server and according to load balancing gets sent to 1 of 5 available RDS servers.

@saige

The RDS services are all started but only the gateway server has the "Remote Desktop Licensing" service (STARTED).

What local or domain groups is your administrator account part of compared to the Limited User?

@VB ITS

"Remote Desktop Services" is started on all my servers. Still missing usernames.

@Hodor I recently deployed a 2008 R2 RDS farm myself and I can't seem to replicate this issue on my end. The servers are running 2008 R2 Standard though and not Enterprise as you are using.

Have you tried going through the local groups on the Remote Desktop Servers to see if the Domain Admins group isn't in one it shouldn't be?

Seems to be a privilege issue with the account.

@VB ITS

I ran into the same issue with the old farm which was standard. I would agree the problem here is a privilege issue with the admin accounts used.

I found an account that worked! One of our admin accounts had special privileges and after logging in as that user I was able to see all usernames. Now I need to find which user rights my other admin accounts need. The admin account that worked were part of the following groups under GPO Computer>Windows Settings>Security settings>Local Policy>User Rights Assignment

Back up files and directories
Debug programs
Log on as batch file
Log on as service
Manage auditing and security log
Modify firmware environment values
Restore files and directories
Shut down the system
Take ownership of files or other objects

I'm thinking it's Debug programs. Compare the two accounts - which User Rights Assignments are missing?

I'll fire up a test 2008 R2 VM shortly to test on my end.

@Hodor - In answer to your question, the Administrator account that I am using is a member of Domain Admins, which is a member of the RDS Server's Local Administrators Group.

OK just fired up a fresh test 2008 R2 Standard VM with just the RD Session Host role installed on it. I removed Administrators from the Debug programs User Rights Assignment (which I will now refer to as URA), logged off, then log back on.

Opened up the Task Manager and I could immediately see a few processes where the User Name column was blank. Re-added the Administrators group to the Debug programs URA and logged out then logged back in. User Name column was showing all the values in the User Name column for each and every process again.

I'd be willing to bet your admin account hasn't been assigned the Debug programs URA. Try adding your specific admin account to this through Group Policy or even through the Local Security Policy (Start > Run > secpol.msc) - should fix the issue.

Debug Programs group was the source of the problem. Thank you all for your help!
