how to make the windows server become a NTP server (not SNTP)?
I want to synchronize the router with this windows server.
You can run the same xntpd daemon on your windows server that the unix boxes use. The latest Windows port can be found at:
Ideally the windows server will sync to two or more ntp servers. Either at your ISP or public stratum 2 servers. Lists of public stratum 2 servers and everything you ever wanted to know about ntp can be found here: http://www.eecis.udel.edu/~ntp/
