I am getting the error "the ntp server didn't respond" in the system event log on my domain controller. This just started happening. Previously I was using tick.usno.navy.mil and tock.usno.navy.mil as my server and I never recieved this error. After the error started I pinged them and noticed they were not available. So I changed my sntp server too now.okstate.edu which responds too pings. I did this last night and I am still getting the same error though.
I have been using the net time commands too perform this on my domain controller. I read a few articles on the use of net time and w32time on the internet and I can't see any reason why this error is occurring.
Anyone have any ideas?
