Windows 2000 domain controllers may fail to dynamically register the
globally unique identifier (GUID) DNS records in the forest root zone.
The following event will be logged:
Event Category: None
Event ID: 5774

Registration of the DNS record
'0ae9d36d-1c8c-4aa4-8130-11a140138bc6._msdcs.Name.com. 600 IN CNAME
ns2.Name.COM.' failed with the following error: DNS RR set that ought not
exist, does exist.
When the Netlogon service tries to register the GUID record in the _msdcs.forestrootzone, the GUID record may not be registered if there is an MX record that is wildcard character (*). The Netlogon service does a DNS query of type ALL for the guid._msdcs.forestrootzone. If a wildcard record exists, the DNS server responds to the query with the MX server information and the dynamic update does not succeed.
