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 Type:
Error Event
Event Category: None
Event ID: 5774
Date: 6/24/2002
Time: 3:38:21 PM
User: N/A
Computer: NS2
Registration of the DNS record
' 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.


Windows 2000 Domain Controller Request:
Question Section: of Req type for All on class INET addr.
