From Softros Systems:Network Time System is a full-featured network time NTP Server and NTP Client allowing synchronization of all computers and devices time on the network with Internet time servers or any other local source of synchronization (other NTP server, GPS cards, radio clocks). This powerful NTP server, client software enables you to set up a virtually fail-safe synchronized time environment for networks of any size and complexity, from small office networks (LAN) to those maintained at large enterprises (VPN, VLAN, WAN), from single site networks to those including numerous domains and involving complex routing techniques. Network Time System supports both its own proprietary time protocol and the world's most widely-used NTP, SNTP and NMEA 0183 GPS time receivers via COM, USB, Bluetooth ports, TCP/IP,UDP multicasting.

Seems that NTS is only windows ntp server software that works out of the box. We just deployed 10 Server and 550 Clients via group policy and registered timeserver.nts local domain on company DNS that's points timeserver.nts host to all 10 server in round robin mode. That's it, now all 550 clients sync with server with absolutely no any configuration on client side! Took a half hour to make this system work, excellent!
Did find any of them.
If you need ntp time server \ client system that's easy to install with almost zero configuration -- NTS is you choice
installed 2 servers in different subnets one as primary and second as backup one, then deployed client app to all 800 windows machines via active directory policy. after that I configured DC DNS server as round robin DNS fail-over for timeserver.nts host which client app requests by default - works like charm now. Zero configuration on workstations side.
logging cannot be configured to what events to log (they log everything)
Recommend this tool if you want to have very accurate time on all your computers and want to deploy it in minutes...
