PDC time sync keeps changing
I have my PDC set up to sync time from an external time source, when I run a "w32tm /resync" it sync's the time correctly and then about a minute later it changes it back to being 2 minutes fast. I will add the results from the configuration query. I need to know what is causing this issue and how to resolve.

That seems to have worked, now to get all the servers to sync to that PDC.
AnnounceFlags is correct (set to 5) for the PDCe.
Is this running as a VM? Make sure that it's not syncing to the host if it is.
I usually recommend using a 0x8 flag after the ntp server to specify to query in client mode as some ntp servers won't respond otherwise. Example below.
0.us.pool.ntp.org,0x8
