[vpn-help] Shrew disables NetBIOS on NIC when VPN connects

[David A. Esquivel]

Also, by the way NetBIOS is only used on workgroup networks.  Active Directory networks rely almost entirely on DNS for name resolution so your problems will only get worse if you decide to move up to AD.

NetBIOS is not the only thing it disables.  It also resets the DNS servers to "acquire automatically".  I've posted this as a bug on the developer list already.  At the very least, it's an oversight.  In my case I have a very specific DNS configuration that I want my mobile users to have.  But when they connect to the VPN it gets replaced with whatever the default local wireless settings are.  The workaround that I had to do was to write a batch file using a series of netsh commands to put it back the way I want it.  The same will probably work in your case.  The downside is that the user must remember to run the batch file after they connect.

Hi Brandon,

Did you by any chance disable WINS in the VPN Site Configuration?  Does 
that maybe push a NetBIOS disable back down to the network adapter used 
to carry the tunnel traffic?
