SYMPTOMS
An error message is written to the event log of domain controllers every five minutes indicating a problem with the domain synchronization. While SAM and BUILTIN Full synchronization is successful, LSA Full Synchronization fails with the following system event log entries:

  PDC: NETLOGON: 5714 The full synchronization request from the server "bdc" failed with the following error: More data is available.

BDC: NETLOGON: 5718 The full synchronization replication of the LSA database from the primary domain controller "pdc" failed with the following error: More data is available.



CAUSE
Replication of the LSA database fails when using long service names. The buffer size reserved to hold LSA data depends on a maximum name-length variable that was too small. The problem does not occur in Windows NT 4.0.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 3.51. A supported fix is now available, but is not fully regression tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next service pack that contains this fix. Contact Microsoft Product Support Services for more information.
