Esentutil & ntdsutil both show no issues when booted to DS restore mode while dcdiag, replmon, nor repadmin show any errors.
OS: Windows 2003 R2 (both 64- and 32-bit) as up to date as possible. Note: ALL DCs report this error with NTDS logging at 5--but no other errors.
This issue is preventing the promotion of both 2008 and 2012 servers to DCs.
All NTDS logging is up at 5 in hopes of finding other messages, to no avail.
No other errors are logged, just this one blank item.
