Status message: The RPC server is unavailable. From a newsgroup post: First check the following entries in the registry:
If these entries could not be found just add them, reboot and the problem is solved.
Status message: There are no more endpoints available from the endpoint mapper. The Microsoft article ME189007
may help. According to a newsgroup post other possible cause (if replication doesn't work) is that the Kerberos tickets from a Domain Controller may not be valid on other Domain controllers in the domain. In this case the following actions can solve the problem:
1. Set the Startup type for the Kerberos Key Distribution Center service on
the affected DC to Disabled.
2. Restart the affected DC.
3. Log on and force replication with its replication partners through the
Active Directory Sites and Services snap-in.
4. Check the replication status with "repadmin /showreps" (without the quotation marks). Repadmin is available in the Windows 2000 Support Tools. If
replication is now successful, set the Startup type for the Kerberos Key Distribution Center service on the affected DC back to Automatic.
5. Restart the Kerberos Key Distribution Center service.
