I disabled the TCP/IP NetBIOS helper on my Windows 2003 DC and can no longer access the domain group policies. The functional level of the domain is Server 2003 native, and I only have 1 DC. If I enable the service, everything works like it should, but I'd like to completely get rid of anything that is related to NetBIOS.

I read somewhere that this service is needed to process the group policies, but does anybody know why?

Also, for some reason after I disabled NetBIOS, I no longer can connect to the shares hosted on the DC by using its DNS name. It works when I type \\\Share, but doesn't when I type \\\Share or\Share.
