Recently the licesning model on my Windows 2008 R2 terminal server changed from Device to Use CALs.
Now all Windows CE terminals are unable to connect, getting the error "Becuase of a security error, the client could not connect to the remote desktop. Verify that you have logged on to the network,and then try connecting again."
We have factory reset the Windows CE terminals but no luck. Other users are connecting to the remote desktop via MSTSC of laptop/desktops and from Sun Terminals. I suspect it is do to with the change from Device vs. User CAL licensing model however not sure how to fix it.
Scratching my head...cheers!
