reset on zero vc

This boolean option controls whether an incoming SMB1 session setup should kill other connections coming from the same IP. This matches
the default Windows 2003 behaviour.
Setting this parameter to yes becomes necessary when you have a flaky network and windows decides to reconnect while the old connection still has files with share modes open. These files become inaccessible over the new connection.
The client sends a zero VC on the new connection, and Windows 2003 kills all other connections coming from the same IP. This way the locked files are accessible again.
Please be aware that enabling this option will kill connections behind a masquerading router, and will not trigger for clients that only use SMB2 or SMB3.

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
