how to return the handle of the remote desktop connection to remote machine.

Hi,

I am trying to overcome a peculiar situation, I have machine A from which I am making a remote connection to machine B, using mstsc , doing this terminates any logged-in session in machine B and passes its handle to session A.

Now , is there a way in which I can pass this handle , which is currently under machine A back to machine B ?

I do not have the option of physically going to the remote machine and logging.

Can this be achieved ? please help !!

Thanks,

Nikhil
