SAM error

[NIC]

hi this is the msg that iam getting on my ADC

The account-identifier allocator failed to initialize
properly. The record data contains the NT error code that
caused the failure. Windows 2000 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.

event id :16650

kindly suggest

You have a couple of solutions here, looks like your RID Master is offline
perhaps?
