Verify Active Directory Replication

FRS replication depends on Active Directory replication. The first step is always to ensure you have correct monitoring processes for Active Directory replication. The simplest way to check for any suspicious Active Directory issues is to execute

FINDSTR "FAIL" ds_showreps.txt

If any issues are found, see article 229896, "Using Repadmin.exe to Troubleshoot Active Directory Replication" at http://support.microsoft.com/?id=229896.
