The NetBIOS Proxy, which is enabled by default, allows RAS clients to resolve theNetBIOS 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_MACHINESystemCurrentControlSetServicesNetbtParametersEnableProxy is a 2.

To disable the NetBIOS Proxy:

1. Use the Registry Editor to navigate to
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesRemoteaccessParametersIp.

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.
