Syncing time with Windows Server Dual Booting systems

[DemiSheep]

I am about to work on getting the workstations on my network here to be connected to the Active Directory on my Windows 2003 server using Likewise Identity Service. One of the security requirements is a good time sync, so I am trying to setup my Windows server time server on my CentOS machines. These machines dual boot Windows 7 and CentOS 5.5. I am using the Windows server as a time server and it's getting its time from its CMOS. Following a microsoft kb article. I removed all the time servers from the CentOS box I am experimenting with and added the IP of my Windows server, it seems to connect ok but the time never gets updated.

Oh, and this network has no connection to the internet, it's cut off from the world, so sad and lonely and cannot get internet time!

Any ideas?

Thanks,

Posting your ntp.conf might help. Otherwise, you should make sure the ntpd service is running. i.e.
chkconfig ntpd on
service ntpd start

If your time still doesn't sync, then you might try setting up a cron job that runs ntpdate periodically.

Where do I find the ntp.conf file?

Have you tried using Wireshark to compare what happens when syncing with an Internet server and the Win 2003 server? It helps if you know how to do filtering with Wireshark but not essential.

...don't have internet.

As a side note, I just noticed that when I reboot the system, when CentOS is shutting down and all the text is running by I see it say "syncing hardware clock something or another"

As another side note, these machines have never had the correct time, and then I try setting them to the correct time manually they always go back to having some crazy time. Like right now here it's 8:30AM but the CentOS machine says it's 4:15AM or something like th at.

Another side note, I just checked the windows side, and the windows side is synced with the server to the exact second.

Also, the Linux side has the right minutes, it's just 4 hours off, 4AM instead of 8 AM

Check your time zone settings on both machines. Are they the same and correct?

Yes, the CentOS machine is showing New_York, the server is showing Eastern Time zone.

Normally I'd say check firewall settings. I know Server 2003 has its off by default. The Ubuntu box should be blocking anything pertaining to ntp. Have you tried syncing time with say an XP VM, or physical machine? See if something can sync off the server.

Edit: News flash - Windows doesn't always play nice with standards and protocals
