Can anyone tell me how to remove NETBIOS traffic in my office. I have disabled "TCP/IP NETBIOS helper" for that under services of my Windows 2008 standard domain controller. But all of a sudden, the group policies stopped working and giving me error "Failed to open group policies, The network path was not found". When I enable NETBIOS service, then group policy works properly. How do I stop NETBIOS traffic? Thanks for any information.
