So my questions are: 1) What is telling my PC to sync with DC2? 2) I've read that is not a reliable time source. So as far as I can tell, none of my DC's are set to be an NTP server. Doing the same on my PC, the registry keys look identical to DC2. Doing the same on DC2 (where my PC appears to be synch'ing it's time), NTPServer key is set to ',0x1' and the Type is set to NT5DS. Checking the registry entry on DC1 (the PDC Emulator) for the W32Time service, the NTPServer key does not exist and the Type is set to NT5DS. DC2 is NOT the PDC Emulator on our domain. On my PC, which is joined to the domain, I see the event ID 35 in event viewer that says it is now synchronizing the system time with the time source 'DC2'. The network time on our domain is off by approximately 5-6 minutes and I'm not sure exactly how to fix it.
