Most likely, there are 2 disconnected sessions still present, which
stop you from connecting to the server. Configure a time-out limit
on disconnected sessions to avoid this problem in the future.

That you can't stop or restart the Terminal services service is by
design:

For the TS Manager issue:

Q. Terminal Services Administration tool starts minimized and can't
be maximized

A. The problem is that at some point the TSAdmin 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.
To solve the problem, start regedit and navigate to this registry
key:
  HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion
\Terminal Server\TSADMIN

Delete the "Placement" value and exit regedit.
Now start Terminal Services Administration and you should be able
to find it.

Services Manager
