What is PDC emulator and how would one know whether PDC emulator is working or not?

PDC Emulators: There is one PDC emulator per domain, and when there is a failed authentication attempt, it is forwarded to PDC emulator.  It acts as a “tie-breaker” and it controls the time sync across the domain.

These are the parameters through which we can know whether PDC emulator is working or not.

  • Time is not syncing
  • User’s accounts are not locked out
  • Windows NT BDCs are not getting updates
  • If pre-windows 2000 computers are unable to change their passwords
