I have a 2003 domain controller and installed Symantec 10.1 antivirus. At this point everything seems to be fine. As soon as I do a live update on antivirus I can no longer access active directory because it cannot find the domain controller. I have an image of the box so I can get back to this point in a matter of minutes. Once I can no longer get into active directory I acn no longer get into the configuration of Symantec. I have even excluded all files on the hard drive from being scanned ie. active directory. This is driving me crazy. Any one have any ideas.

Probably you have problems with firewall settings.
I hat the same problems with a 2008 domain controller and after turning of windows firewall everything works fine.

I agree with is probably the firewall. Make sure that you have ports open to allow LDAP to function properly...sometimes simply disabling network threat protection solved it for me...but it might be a good idea to add the port to the 'allowed' list for the future; sometimes if you need to reboot boxes (either the DC, or the SEPM server) (this i have noticed in symantec 11, even with policies applied to our 'servers' group), any applied policies don't seem to be applied, and we have to manually turn off threat protection...

manually adding network browsing ports (if not automatically enabled), will definitely save you some headache in the future...this i have learned...
