[Samba] Stop WinXP from attempting to remount a share

[Jason Mader]

I've noticed that a Windows XP client continually tries to reconnect to 
a Samba share that no longer exists.  This is despite rebooting, and 
despite having disconnected the share on the client.

Windows seems to persistently remember the server\share and want to 
reconnect with it.  Is there a way to stop this?
