Question : Terminal Server allowing multiple sessions for one user

I have seen this on every terminal server I have ever administered.  One user having multiple terminal session active at one time.  The user will login in the morning and start a session, the connection drops and the user get kicked out.  The user then reconnects, but instead and handing off the existing session back to user, the server allows a new session to be created.  Now we have 2 sessions open for the same user.  I have seen times where it would prompt the user on which session to connect too, but very rare.  The end result is that the user could documents and programs open on multiple sessions without realizing it.  This causes problems with open file and file locks.  How do I get the terminal server to consistently prompt the user to reconnect to the previous session, or just auto-reconnect the user.  I am sure this is a very common issue, but I did not find anything in the KB.

Answer : Terminal Server allowing multiple sessions for one user

You can try this thing
1. Open Terminal Services Configuration console on the terminal server
2. Highlight connections on left side and on Right side, right click Rdp-Tcp properties
3. In Sessions tab, Select Override User Settings and choose "When session limit is reached or connection is broken:" End Session option

you may try this and let me know.
