Sometime in the last year or so, our SBS server's clock has been falling slowly behind, but now it has jumped ahead by about 11 minutes 27 sec
We used to manually update the time, but now when I update the clock, it stays for a bit and then jumps back ahead. All our user logon scripts set the time to the SBS and it's causing confusion as to what time it actually is for emails,electronic documents, etc.
The Windows Time service is running, I did a restart on the service and got a windows event saying: "The time provider NtpClient is currently receiving valid time data from time.nist.gov (ntp.m|0x0|172.16.1.6:123->18.104.22.168:123)."
If I run a net time /querysntp on the SBS I get: time.nist.gov,time.windows.com
Current time on our servers is 12:11:27. Current time on Time.gov is 12:00:00
What could be causing our time to be off, and how can I get it back on track?
