I have an ESXi 5.1 server configured as a NTP server and a local Windows Server 2008 R2 PC that aren't syncing. I've read that whenever an ESXi server is run as a client, it also acts as a server, so I enabled it as an NTP client and simply added no servers to the server list, and then I enabled port 123 incoming/outgoing by adding firewall settings from the ESXi Shell.
I'm almost positive that it's not a firewall issue. I've completely disabled the firewall on my local PC. Running "w32tm /monitor /computers:-IP of server-" gives me the time of the server, and running the NTPQuery software gives me a response back on port 123 with the server's time.
I have tried:
- Date/Time settings (right-click on notification area-->Adjust date/time-->Internet Time-->set as IP of server) -- syncing fails (An error occurred while Windows was synchronizing with -IP of server-)
- Group Policy Editor (Computer Configuration\Administrative Templates\System\Windows Time Service, currently disabled though because I've heard this causes problems) -- syncing fails
- Registry Editor (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\W32Time\settings) -- syncing fails
- Command Prompt, using:
w32tm /config /manualpeerlist:-IP of server- /syncfromflags:MANUAL /reliable:yes /update net stop w32time && net start w32time w32tm /resync /rediscover
This updates the registry correctly, but outputs "The computer did not resync because no time data was available." And whenever I use the command "w32tm /query /source" the source is always "Local CMOS clock."
Here is the output of w32tm /query /configuration

Any ideas? Thanks in advance.
