I recently "activated" a Remote Desktop Services manager on our 2008 R2 DC. We have an application server that often times quires more than 2 users would try and connect to but the licenses were all in use - so I picked up an 5 additional licenses and installed them as noted on the above server.
Now however I'm unable to remote desktop into our 2003 app server at all. I've checked event logs on both servers and there doesn't seem to be anything wrong with either box. Under "terminal services configuration" on the app server under licensing it says "remote desktop for administration". There's no other option and to make any changes it says to do it through add/remove programs but doesn't really tell you want you need to change in there. From the 2008 Remote Desktop Services Manager I can add my app server which shows a green "up" arrow in the list on the left pane but in the right pane under "sessions" tab it shows a red "down" arrow - yet for state it says "Connected".
Am I missing something on my 2003 app server? Any suggestions on how I can correct this?
