Terminal Server 2008 Huge amounts of data sent out to user(s)

Posted on 2011-05-12

Hi all, bandwith at our branch offices seems to be throttled by some of ur terminal server users. We have about 20 users on at any one time, 8GB of RAM, of which 4/5GB is constantly utilised. Is this a problem? CPU usage is low except when it spikes when people open up docs and programmes etc.
However some staff connect in from home via TS Gateway, which incidentally is on the same server as the TS, not ideal but there we are, and i can therefore see the amount of data sent to them in kilobits.  One user received 225MB from us yesterday! Im not sure if Adobe reader on the TS is partly to blame because as soon as he opened a PDF i kept refreshing and the amount of data sent to him was about 10MB in a minute or so!  However i couldnt replicate this scenario with another user when i tried it to be certain that this was the cause but i will try again with another user.  However if we were sending that amount of data over our line to him then i guess that leaves hardly any to service our branch office users?  we do have a 10MB leased line but even that probably couldnt handle what we were sending to ihm and then all of the other offices, hence the slow down of TS for the other office users. ive enclosed a screenshot of the users TS gateway connection so you can see the volume of data sent. Any help or recommendations on how to solve this would be much appreciated.

    it seems that any app will spike the amount of data sent but it seems like a lot to be sending and the slowdown for other users seems to bear this out. can someone please help me, this is driving me crazy!!

    Is there multimedia content in this pdf? That can add up the amount of data being sent fairly quickly. What about shared drives? Printing? etc. Perhaps there is a print job queued to his local printer?

    Try limiting the rdp features on this user to see if that helps. Configure him/her as a slow connection to cut down on the amount of graphics data being sent. You will probably have to experiment a bit...

    Hi - he doesnt have a printer at his house - i actually think its becasue all of the files that users open arent actually on the terminal server - they are on a DC on the network so they are opening all files via mapped network drives - it doesnt send anywhere near as much when i tried opening a file that was held locally on the terminal server - ill play about as you said and see where that gets me.
