Graceful exit from remote host?

[odinanne at comcast.net (odinanne)]

I have been  using the lsass exploit with the win32_bind payload and 
have been able to successfully receive the remote shell.  After exiting 
the remote shell with exit, quit, control c I am not able to get the 
exploit to work a second time.

What is the best way to exit the remote shell?  Am I crashing the lsass 
service?  Any ideas or suggestions would be appreciated.

Thanks
