I have two Windows Server 2008 R2 Standard servers. The first can correctly sync its time with the default NTP server time.windows.com, but the second cannot.
The error displayed is:
An error occurred while Windows was synchronizing with time.windows.com
I installed Wireshark on both, and tried an NTP sync. On the working server, I can see the NTP request, and the NTP answer. However on the second server there is no NTP request (Wireshark sees nothing).
The filter I applied in Wireshark is simply "ntp".
I tried to restart the Windows Time service, and disabled the firewall but the problem still persists. How can I fix it?
