VPN and NetBIOS over TCP/IP setting

Many days from now our vpn is not working properly anymore.
every thing goes well at the time to authenticate and logon to the network
but after that i cannot access any resource or computer.

I researched in technet and i found the problem.
The NETBIOS over TCP/IP setting was set to "Disabled" and that was blocking
communication to the resources.

I changed the setting and everything worked fine again.
The problem now is that the setting is back to disabled. My guess is that a
Group policy is set to change this setting.

Does someone know wich group policy could be affecting this or if another
program is changing the NETBIOS setting back to disabled.

We have ISA2000 installed.

Thanks

Maybe you get the NETBIOS configuration through DHCP options. If this is the
case then check the DHCP options.
