I have a strange problem with RDC I have a remote desktop client that gets this error when it tries to connect to the TS server. "The remote session was disconnected because there are no terminal server client access licenses available for this computer" the thing that really gets me though is that if I connect with another machine it connects just fine. Any ideas on why just one machine would have this problem?

This is generally caused by users not logging off from Remote Desktop properly. If you close the remote desktop session by just clicking on the x in the top bar, it only closes the window but leaves the session open on that pc. Eventually, when the maximum amount of sessions has been reached, the server will display the error message that you are receiving. On the other pc's you need to open the Remote Desktop session and then click on 'Start', then 'Log Off', then click on 'OK' when it asks you do you want to end the session. you will need to do this on all of the pc's that have current Remote sessions open.

Alternatively, you can either reboot the server to close the sessions, or use Terminal Services Manager to manually end the sessions on the existing client's.

hope this helps!

Thanks Lee I will try that asap. kgreeneit I know what you are saying, you are suggesting that by not logging off that I'm running out of licences but I am logging off and I'm only currently using 8 of 15 licences. so that shouldn't be the problem.

Okay Lee I have already read your suggestion before I posted here, I'm not out of licenses and I don't think it's the license server or the other machines that I am connecting with would not be able to connect either, I connect with one fine log off and try to connect with the other and I get the other, but if I try to connect with the first computer again, once again it connects fine.

hay ! i have just got in to this corner too ..
in fact,it's the second time i have this but since it's my personal server last time i formated.
this time i decided to fight it !!
any way, from my digging in the net i discover that terminal server need CALs to work.
when you install server 2003 it comes with limited number of them to alow you to connect the server
but after some time of using the remote desktop they run out and then you need to buy some  more.
my solution was to remove terminal server (from add/remove windows components)
then enable the remote desktop for administartion from : right click on "my computer" -> "remote" tab.
reboot the server and done ! i'm abale to connect with RDC again.

*** note that this alow to only TWO pcs to connect simultaneous .
       after all it for admin purpose.

cheers !

My problem is I'm not out of cals and I can connect with every computer in the office using RDC except for one, even if I go into the terminal services management console and manually end every session leaving me with 15 open CALS I still can't connect with this one computer, this tells me it's on the client side not the server side.

okay I'm going to split the points as Lee came up with some really good suggestions to fix the work station, however I just didn't have time to leave so I was forced to change the licence mode to make this work even though it was my last resort, I just needed it working. Thank you all!!!
