winupd - Windows Uptime Monitoring Daemon

This program monitors the uptime of Windows clients on a network through the broadcasting of a type of NetBIOS announcement known as a "Browser Election Request". Part of this packet includes the broadcasting computer's current uptime. This can only be observed on the local subnet, but a future release will add the ability to peer computers running winupd so they share their information. You can view the results of the last time I ran it.
