Hi All

I am having a problem with server sync time, server is sitting in DMZ, I have tried to use the following

net stop w32time

w32tm /unregister
w32tm /register

w32tm /config /manualpeerlist:192.43.244.18 /syncfromflags:MANUAL /reliable:YES

net start w32time

w32tm /config /update

w32tm /resync /rediscover
and I have edited the registry  w32tm =>Parameteters=>type =NT5DS (see image)

I keep getting the following error
C:\ >w32tm /resync
Sending resync command to local computer...
The computer did not resync because no time data was available.


I know the local NTP server is working perfect as all other servers on  the network are fine and hence internal NTP (NT5DS) server is perfectly functional

I have checked out few links on the internet and nothing helps and I have also tried to sync the server with external NTP server such as ntp.mel.connect.com.au from the following website and others but still no go I get same error as above

http://info.connect.com.au/docs/ntp/index.html

I have checked the port 123 for NTP and on server it is running fine but I don’t know how I can test the port connectivity i.e. this is UDP port and TELNET will not work with it, so is there way I can test the port connectivity? See image2 I need to see if firewall is an issue?

If you require any further information please feel free to ask

Thanks in advance

Maybe is a problem on firewall config or remote server. Check that you can get ntp from external server. Try this command that give you time diference between your server and external ntp server:

w32tm /stripchart /computer:192.43.244.18 /dataonly /samples:4

I can´t see your firewall config. Firewall is installed on PC or on gateway?

Of course, telnet is a TCP and can´t telnet over UDP, you can´t test using this, but can use a scan port to do this.

The server had corrupted registry entry, after extensive research and fiddling i managed to resolve the issue. It was not firewall issue at all. Case is closed now

Thanks
