C:\Program Files\Resource Kit>uptime
\\SUPERNOVA has been up for: 19 day(s), 12 hour(s), 10 minute(s), 39 second(s)
Last reboot was to install some critical updates, IIRC.
AMDPwred: In Win9x, you could run System Information and it would say there, but not in Win2k. If you have the resource kit, just run the command I mentioned above. If not, you're SOL.
