I have three domain controllers, 2 are 2003 r2 and 1 is 2008 r2. The PDC controller is a 2003 r2 machine and it holds all of the fsmo roles. I have been syncing with a local external time server for over a year with no problems but recently I have noticed that the time is out, fast by about 7 minutes. I have checked all the settings and reset them up so that the PDC DC is the only one syncing with an external source and all the others sync from it.
I have tried other time servers but get the same result.
When I run a w32tm /resync /rediscover on the PDC DC, it changes the clock to the correct time but only for 10 seconds and then reverts back to the wrong time.
When I run w32tm /monitor, it shows the PDC syncing with the external source and the other 2 syncing from the PDC and all are the same time so at least thats right!
Help! I dont know what else to do but I really want the right time.
Thanks in advance
