On a domain controller that runs Windows 2000, Event Viewer may log the following Domain Name System (DNS) events every 12 to 15 minutes:
Event Type: Error
Event Source: DNS
Event Category: None
Event ID: 4000
Description: The DNS server was unable to open Active Directory. This DNS server is configured to obtain and use information from the directory for this zone and is unable to load the zone without it. Check that the Active Directory is functioning properly and reload the zone. The event data is the error code.
Data: 0000: f5 25 00 00
Event Type: Warning
Event Source: DNS
Event Category:None
Event ID: 4013
Description: The DNS server was unable to open the Active Directory. This DNS server is configured to use directory service information and cannot operate without access to the directory. The DNS server will wait for the directory to start. If the DNS server is started but the appropriate event has not been logged, then the DNS server is still waiting for the directory to start.
Data: 0000: f5 25 00 00
These events are logged even though Active Directory (AD) appears to be running, logons are successful, and various AD tools work.
When you try to move a DNS zone, you may receive an error message that says, "The data on the Primary zone failed to set; AD service is not available."
If you run the command
DCDiag /test:services /v, you may find that the Intersite Messaging Service is not started.
In addition, Event Viewer may record the following Directory Service events:
Event Type: Warning
Event Source: NTDS Intersite Messaging
Event Category: Intersite Messaging
Event ID: 1473
Description: The Intersite Messaging Service failed to read the configuration of the Intersite Transports out of the Directory. The error message is as follows:
Unable to update the password. The value provided as the current password is incorrect.
The service has stopped. It will be necessary to correct the problem and restart the service in order for intersite communication to occur. The KCC will be unable to calculate intersite topology without this service. There may be a problem retrieving data from the LDAP server. Please verify that LDAP queries are succeeding on this machine. You may also wish to try restarting the Intersite Messaging Service manually. The record data is the status code.
Data: 0000: 2b 05 00 00

Event ID: 1655
Description: The attempt to communicate with global catalog \\computername.SoftwareManager.TheSoftwareManager.com failed with the following status:

Event ID: 1000

There are no events in the File Replication service (FRS) to show that Active Directory is up and ready, and running DCDiag for the FRSSysVol test may not succeed.
If you run the command
ntfrsutl sets, you may find that nothing is listed in active replica sets.
If LDAP binds in the system context by using Kerbos, the binds may not work. However, the binds may succeed with NTLM. A network trace reveals a failed LDAP bind, and you receive the following error message:
W8009030C LdapErr: DSID-0C0903E2, comment: AcceptSecurityContext error, data 52f, v893.
Finally, running the command
ntfrsutl DS may result in an error on ldap_open, along with the following error message:
Error: 0x00000031 = Invalid Credentials.
