Before you can troubleshoot FRS, you must verify that the FRS
dependencies are working properly on the server experiencing
problems. If any of the dependencies are not working, any time
spent troubleshooting FRS is futile.
After you verify these dependencies, proceed to Choose the Replication Type.
If you are not sure how to check these dependencies, contact
Microsoft Product Support Services for assistance.
DNS
Use NETDiag to check for errors. (NETDiag is part of the
Windows Support Tools.)
If possible, point all FRS servers to one Windows 2000 DNS
server for testing. For additional information about DNS, see the
following articles:
275278, "DNS Server Becomes an Island When a Domain Controller
Points to Itself for the _Msdcs.ForestDnsName Domain" at http://support.microsoft.com/?id=275278.
Use Terminal Server session (if possible) to check for network
connectivity.
