Terminal Server “The requested session access is denied” when you try to login

April 20, 2012 by Wayne Small 18 Comments

I was working on this issue today with one of our team.  A client reported that they could not login to their Windows Server 2008 Terminal Server from their iPad.  He is using iTap on his iPad.  The error message we kept getting was “The requested session access is denied”.

We verified that we could access the Terminal Server / Remote Desktop server using our Admin account and thought that maybe it was linked to the clients account.  He brought his iPad into the office and we tried the Admin account from the connection he had created.  It worked.  We then thought that we’d try it from a desktop using our admin account – that too worked, but when we tried it with his account it didn’t work.  Strange we thought – I mean we just launched mstsc.exe from the shortcut we had on our desktop…  After a little bit of digging and thought though, it finally clicked.  Access is denied… We checked and found that our shortcut used the /admin switch which meant that it would try to take over the console session on the server.  Given that we got the same message with both the desktop and the iPad, we then checked the iPad to see that it had a similar console option in the iTap configuration.  Changed that and sure enough it worked!

    You sir have helped me nail why I was getting access denied.
    I removed the “administrative session:i:1” from my .rdp file and joy followed.

    Editing my .rdp file with a text editor and removing this line worked for me. “administrative session:i:1”
    Thank you for the post!
