JSI Tip 5558. How do I disable the NetBIOS Proxy on a Windows XP or Windows .NET VPN or RAS server?

The NetBIOS Proxy, which is enabled by default, allows RAS clients to resolve the NetBIOS names on the LAN that the RAS client is connected to.

If you open a CMD prompt on the VPN or RAS server and type ipconfig /all, you will see that WINS Proxy Enabled is set to Yes.

NOTE:  WINS Proxy Enabled is set to Yes when HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Netbt\Parameters\EnableProxy is a 2.

To disable the NetBIOS Proxy:

1. Use the Registry Editor to navigate to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Remoteaccess\Parameters\Ip.

2. Change the data value of the EnableNebtBcastFwd Value Name, a REG_DWORD data type, to 0.

3. Shutdown and restart your RAS or VPN Server.
