Network Time Server for Windows

From $139 per server plus $10.95 per client, volume discounts, 1 year of maintenance included

Network Time System takes the guesswork out of keeping clocks in sync across your network. This client/server application builds a reliable, self-correcting time environment that scales to networks of any size and complexity — from a single-office LAN to enterprise infrastructures spanning VPNs, VLANs, and WANs, multiple sites, numerous domains, and intricate routing setups. Rather than depending on outside time sources, it establishes your own authoritative source of precise time inside the corporate network, then distributes it to every machine and device connected to it.
