Sync Linux to Windows 2003/2008 Natively
Solution 1:
You can use the "net" command from the linux box:
net time set -S <server>
Solution 2:
PDC (Primary Domain Controller) works as a NTP server - you can simply point your Linux box to it. If you want to configure it outside of Active Directory, the process is a bit different: http://www.techrepublic.com/blog/datacenter/configure-a-standalone-ntp-server-in-windows-server/3869
