Try Rebooting your firewall. This problem discussed before also:

https://www.experts-exchange.com/questions/23841215/Remote-Desktop-disconnecting-after-30-minutes.html

@dipak1383 - I checked all of the things in that blog. No difference.
@sumitgupta85 - I have rebooted the firewall several times. No difference.

Check if there is session timeout policy in group policy then:

Using Local Group Policy Editor (gpedit.msc) there is a setting under

Administrative Templates \ Windows components \ Remote desktop services \ Remote desktop session host \  Connections

saying "Set rules of remote control of remote desktop services" witch lets you specify the interaction mode and the control level for an RDP session

enable it and choose the "Full control without user permission" option. so the logged user won't be prompt for confirmation (there is more details there)

you can also set the Session time limit for active but idle RDP service under session time limit folder to "Never" and it won't disconnect you IDLE.

OS is Win7 or Win8?

if that dont work, then run this command on your computer:

netsh interface tcp set global autotuninglevel=disabled

Or Check if this problem is from every machine in domain.

Thanks @sumitgupta85. It's Windows 7 Pro and only appears to happen on this computer. Other computers on the domain are fine. I'll try the GPO settings and the command and let you know shortly.

you are welcome but also try with another user from same computer to verify if its system problem or problem with particular account.

Ok I've done the GPO changes and the command line. I've also updated the NIC drivers. It happens with any user on this computer - even domain admin.  I'm going to test it for a few hours this morning. Seems to be holding ok for now.

Looks like we're still getting disconnected on a regular basis.

last options:

- disconnect machine from domain and try to connect to server if it works fine.
- rejoin machine with domain.
- check event logs and send me the eventlogs if possible
- last check if some software like juniper etc is not blocking or applying own policy.
- rebuild machine if all steps fail.

it could be possible that some application blocks this connection from system.. Lets hope if your problem resolves at the soonest ;)

Yup. It was the NIC. No issues since then. Thanks everyonne.

THe NIC was the issue
