You notice that an entry that resembles the following is recorded approximately every two minutes in the NTDS event log:
The account-identifier allocator failed to initialize properly. The record data contains the NT error code that caused the failure. Windows Server may retry the initialization until it succeeds; until that time, account creation will be denied on this Domain Controller. Please look for other SAM event logs that may indicate the exact reason for the failure.
This problem occurs because the RID Master FSMO is unavailable or fails to replicate. The domain controller cannot obtain and initialize the RID pool.
This problem may also occur if the "Access this computer from the network" user right is not granted to the appropriate groups, such as the "Enterprise Domain Controllers" or "Authenticated Users" groups.
To troubleshoot this problem, examine the NTDS event log for more details about the replication failure.
