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.
