win32net help

[Shin]

Hi all, I'm new to the python language and I'm having trouble.  I'm 
writing a basic chat script...real basic.  It's client-server based and 
I'm wanting the roles to change -- client becomes server and vice versa. 
  The problem is when I do this, the server switches to the client no 
problem.  However, when the client tries to switch to server mode, it 
can't because the previous server is still bound to the socket it wants 
to use.  I've tried using socket.closesocket and socket.DisconnectEx but 
nothing works.  Any suggestions?  Or could you point me to documentation 
  showing supported commands for win32net?  Any help is greatly appreciated.
