Terminal Services timeouts not applying / applying incorrectly

We have a Microsoft Windows 2003 R2 terminal server with Citrix installed.   The clients that connect to this server have various idle timeout requirements so we have set appropriate session idle timeouts on each account, but these timeouts are not applying properly.

To test I have created an account with a 5 minute idle timeout.   If I leave the account logged in and watch it from Terminal Services Manager, I see the session go idle and the timeout comes and goes.  It stays connected for 60 minutes, then finally goes to a disconnected state.

I've checked local policy, resultant set of policy, the RDP and ICA listeners in Terminal Services Configuration MMC, and the MaxIdleTime values for the listeners in the registry.  None of them appear to indicate that a timeout has been defined.  Where could this 60 minute timeout coming from?

Where are you setting the individual users timeout session at?  In their AD profile?

If you have citrix servers often they have their own group policy (a loopback policy, see here if you don't know if you are using them:  http://www.msterminalservices.org/articles/Managing-Terminal-Services-Group-Policy.html)

If in the loopback policy in the Processing mode properties, if 'Replace' is used then it will not inherit any user settings from AD.  If 'Merge' is used then I am not 100% sure if those setting will come over or not, but that may solve it.

Not sure if that is your issue but that would be where I would start.

Thanks for your reply.  Yes, we're trying to set the session timeouts in the AD profile.

Group Policy loopback processing mode is currently Not Configured in local policy, and we don't have it set in any other group policies.   All of the policies we do have are applied to the user OU's (these users only logon through Citrix)

At the moment I've also placed my test user in an OU which has all group policies blocked just in case.

One new bit of information - I found that if I change the timeout on the AD profile of my test user from 5 mintues to Never, it doesn't seem to disconnect after 60 minutes.

Have you tested using RDP? Some of the terminal services group policies do not apply perfectly to ICa connections.

Yes, I'm testing using RDP and ICA, same results at the moment.

I've opened a ticket with Microsoft and they've pointed me to this article/hotfix:

We have Windows 2008 domain controllers and apparently the timeout values are stored differently in 2008 versus 2003.  Going to install this and see what happens.

Just applied the hotfix to all our domain controllers this past weekend.  It looks like that did the trick.
