SYMPTOMS
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

Source: NETLOGON

Event Category: None

Event ID: 5774

Date: 6/24/2002

Time: 3:38:21 PM

User: N/A

Computer: NS2

Description:

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.



CAUSE
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.

Example:

Windows 2000 Domain Controller Request:

Question Section: 0ae9d36d-1c8c-4aa4-8130-11a140138bc6._msdcs.Name.com. of Req type for All on class INET addr.

DNS Server Reply:

Answer section: 0ae9d36d-1c8c-4aa4-8130-11a140138bc6._msdcs.Name.com. of type Mail Xchg on class INET addr.
