you can also use the uptime utility mentioned above on remote systems as well (assuming you have admin rights). More info on the tool can be found on Microsoft's site here. Personally, I love this little app - and while the article says it applies to NT4/win2000, I can testify to the fact that it also works with XP and 2k3 servers as well.
That is an excellent little tool, we use it alot as well.
I sometimes get lazy and right click My Network Places, and go to Properties.
Then I right click Local Area Connection and go to status. Usually the uptime is the same as the connection to the network. USUALLY.
It works on any OS. It takes the "ticks" and calculated the uptime from there. Windows Server 2003 logs an event at 12:00 PM every day with the "ticks".

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
