Remote application times out after 5 minutes, and RDP remains active
I have 4 terminal servers, all Windows 2003 R2 that runs an application for our remote stores. All stores have Windows XP Pro SP3 and are all members of the domain, etc. etc. I have a GPO where the settings are as following:
- Set time limit for disconnected sessions 1 Min
- Set time limit for active but idle sessions 1 Hour
- Terminate session when time limits are reached Enabled
When a computer connects via RDP to the terminal server, it runs an application. After 5 minutes, the application or terminal session logs the user out of the application and the RDP remains active, but connects the user to another terminal server? Thus closes/logs out the user of the application. With 4 terminal servers, Round Robin is in use for load balancing and balances all connections very well. Most stores have a SonicWall TZ 170 or TZ 180, some with enhanced OS with a VPN connection to a SonicWall 3060, enhanced OS. The settings are all identical to each other.
Additional information, I have tersted with notepad.exe as well, with the same result. Each store has it's own OU with it's users. Each user launches the same program as defined in the user's properties.
Please ask for screen shots, etc. if you find this necessary.

I still do not understand where the problem is and how this is happening. Your post is not very clear and I find it confusing.
Could you post it step by step like?
1. Users at remote location connect to TS using the DNS name.
2. They get a session in one of the TSs.
3. They launch the application A we use.
4. After 5 minutes....

1. Remote user connect to TS using DNS (i.e. kms.best.net)
2. Once connected a program launches automatically (Defined in the user's profile)
3 User logs in to that program and every thing is fine, until idle activity.
If inactive for 5 minutes, the session logs the user out of the program and logs on to another TS server. The program restarts and aks the user for credentials, username and password. RDP remains active, but the program switches to another TS server.

I sensed that there was an issue with DNS Round Robin. The RDP connection stays on, then the application closes and opens on a different TS server. I monitored the PC with connection, as well as the TS Manager and could see this happening. I will read through your articles (Visits these sites quite often, but must have missed something). Because our stores are very active throughout the day, I will conduct some tests, based on your receommendations and return with an answer as soos as I can. Thank you vbery much for you assistance, it's greatly appreciated.

Could I enable/configure NLB while RRDNS is still running for testing purposes?
Yes, you can have NLB up with RRDNS.

You can check the firewall rule that is allowing the traffic for the application, the rules usually have a timeout value of 5 or 15min. That might help the disconnecting issue and then the DNS round-robin won't be such an issue.

I do not believe that I have an issue with our firewalls. All of our stores hvae SonicWall TZ170 and some with TZ180. The firewall behind our TS servers is a SonicWall 3060. The reason I do not think it's a firewall issue is that some stores can have an idle activity running for 60 minutes as defined in the GPO. This I think is related to the RRDNS.
I have compared each SonicWall settings for the stores that are OK with the stores that are not, even replaced a SonicWall.
I'm currently working on the solution that Cláudio Rodrigues recommended with NLB. Cláudio Rodrigues also have great articles that were linked earlier. In addition, I located this link:

Therefore, I will focus on the NLB apporach for the time being. Once I have tested this, I will follow up with a post. Thanks for your feedback.

I have tried to have the user/pc log onto one server via static IP, instead of DNS. This resulted in the same outcome.
