We had a Windows 2008 Server that was functioning as the only server in the environment, AD Domain Controller, file and print service and a terminal server for a handful of users. We added a SBS 2008 server to the environment joining it to the current domain. After this the users Terminal Server sessions time out after about 10 mins of in activity. It was 30 mins before and everything seems to show 30 mins that we can find, but it still times out after 10 mins and the users have to re-enter there name and password to get back in. Any ideas?
