When an account PW is updated on an AD DC (not the PDC emulator), it should be immediately replicated to the PDC emulator. The rest of the DCs are brought up to date during normal replication cycles.
I can build a version of the program that would let you specify a particular computer for which to check the PW age of computer accounts.
How are you determining that the data from the PDC emulator is not correct or not in synch with that of the other DCs? Have you verified that there are not replication issues?
