RDP Session Freezes

Hi Guys

I am running a Windows 2012 RDP Server, I have a number of users from varying locations connecting to this server using RDP. Clients are running a mix of Windows XP and Windows 7 machines.

I am getting a lot of complaints that the sessions are freezing/locking, this happens to me as well. This problem seems to vary some users tell me that it freezes/locks up after 15 mins and others 30 mins, I have done tests from my machine and I can go up to 2 hours without my session freezing however it will eventually freeze.

freeze = leave session for some amount of time without activity and you come back to the session which is a blue screen, you bring the session to front and you have to wait about a minute or so to get your session back, sometimes you are required to enter username and password as well.

I don't think it is a server settings as the times seem to vary so much, I did do some googling and there was information saying to un-tick audio sharing on the RDP client which I did and things did improve for me, that's why my session doesn't freeze for 2 hours or more, I also had the same problem where it would freeze after 10-15 minutes

Does the RDP session get disconnected? Do the end users see 'trying to reconnect messages'?  How long have you let it sit when it looks like it's frozen?

it varies. Sometime it disconnects and you see it trying to reconnect, other times it sits there for about a minute with a blue screen and then comes to life not requiring password or anything

Looks more like a speed / bandwidth issue.  what is the speed up/down at the RDP server side?  How many users connecting at one time?  What happens if for testing you lock it down so one connection.  What kinds of applications are the remote users running?  How much RAM/Disk/CPU's on the RDP Server?

This should be a dedicated server running nothing else like SQL, Active Directory, Exchange.  Obviously things like office can be installed & run  without any repercussions.

* Downspeed:   20Mbps, Upspeed:   2.5 - 3 Mbps
* approx. 10 Users at any given time through the day
* Users are mainly using MYOB and MS Access DB's
* As for locking down to 1 user, even during the evening when I am the only one logged on with no other internet traffic from the office I encounter the same problem
* New high end server.
     * Intel Xeon E5-2407
     * 32.0GB Ram

If it was the office traffic or server performance would my session not have the same issue as the user? My sessions seem to last much longer before freezing, it will freeze, sometimes after 5-10 minutes other times 2-3 hours

Just got back some feedback from the local staff and they have no issues - it seems to be remote users only, some locations seem to be worse then others.

Then I'm fairly certain you can rule out the server itself.
