Under the following situations you may want to reinstall the DDNS in a Windows 2000 Active Directory:
Some weird DNS errors have occurred and clearing DNS information has been unsuccessful.
Services that depend upon DNS, such as, the File Replication service (FRS) and/or Active Directory are failing.
The secondary DNS server doesn’t support dynamic updates.
To reinstall the dynamic DNS in a Windows 2000 Active Directory
- Clear the DNS information.
- Clear the Caching Reslover.
- Point all DNS servers to the first DNS server under TCP/IP properties.
- Re-add the zones and configure them to be Active Directory integrated.
- Register a resource record for DNS as well as your start of authority (SOA).
