Windows 2008 R2 DC NTP sync issue
Posted on 2011-03-11
I have an internal firewall hosting our NTP server.
I would like to set out DC to use this NTP sever
I have added the following:
C:\Windows\system32>w32tm /config /syncfromflags:manual /manualpeerlist:10.1.0.1
C:\Windows\system32>net stop w32time
C:\Windows\system32>net start w32time
But in the evetlog i see:
Time Provider NtpClient: No valid response has been received from manually configured peer 10.1.0.1 after 8 attempts to contact it. This peer will be discarded as a time source and NtpClient will attempt to discover a new peer with this DNS name. The error was: The peer is unreachable.
I have also added 0x8 ... same problem.
I have a small NTP tool - that show the NTP server is responding.
What to do?
