Time keeps going out of sync on domain controller.
Had another look at this as it went 12mins out of sync again today.
We have 2 domain controllers, and have had issue with time sync occasionally since before I started here.
The DC that holds the FSMO roles including the PDC emulator (still Server2003) is set up for type NT5DS (look at the domain for it's time). It has no NtpServer key.
Since being here I have brought in a 2008 R2 after doing all the DCPROMO on the schema as per MS docs.
The 2008 R2 as well as having the type set to NT5DS (look at the domain for it's time), has also got the NtpServer key set to time.windows.com,0x9.
What does the 0x9 mean? and Shouldn't the DC with the PDC Emulator role have a NtpServer key set?
