Terminal Services has ended connection

[Jeff Thur]

Terminal Services was working with no problem up until
yesterday. Now when I tried to access T.S.I get message
Terminal Services has ended the connection. When I try to
open up T.S. manager on the server the manager itself goes
on the task bar and I can't actually open it to look at it
in its own window. I right click it on the taskbar and
click open but nothing happens. I looked at the T.S.
manager on another computer and I see the server listed
but it is not green like it should be. I then checked the
event log and the message states that client license can
not be issued. Does anybody have any ideas on this Thanks

I think you have several different problems.
First the TS Manager problem:

Logged in as yourself, go to this registry key:
HKCU\\Software\Microsoft\Windows NT\CurrentVersion\Terminal Server
\TSADMIN

Delete the "Placement" value and exit Regedit.

Now run the Terminal Services Manager and you should be able to
use it.
The problem is that at some point the TSM window position settings
were saved in a high-resolution session; with it running in a low-
resolution session, those values position it off the viewable
screen.

Now the real problem: licenses:
How is your licensing situation?
Do you have a TS Licensing Server installed and activated?
Have you verified that the TS can locate the LS??
Do you have enough free TS CALs available on the LS?
