Figuring out an IP of a machine...

Ok I have a little problem here. I accidentally logged out of a W2K machine, I have no idea what the admin pass is, and the machine is alone on a separate network that runs through the building (ip range unknown).

I of course have physical access to everything, it's connected to a Linksys switch in the server room.

Is there any way for me to find out the ip of the machine the way things are now? The folder with the program I need access to is shared, so as long as I find out what the ip is this should be enough for now.

I thought about using sw like Softperfect's Network Scanner, but doesn't that require me to know subnet etc?
 
This may not work if the computers are on truly separate networks, but you could try pinging the computer by name from another PC in the building. You can get the computer's NETBIOS name (if you don't know it already) from the Windows login screen. Just click on the drop-down arrow in the "Logon to:" field and look for an entry with (This computer) at the end.
 
Crossconnect the windows machine to another machine and sniff the wire for whatever floats your way, patience may be in order, but usually those machines are pretty chatty.
 
Add another machine to the network and run arp -a in a command prompt. Eliminate other systems by mac address.
 
Thanks everyone!

The switch is not managed. It's a 4-port Linksys.

How do I go about to "sniff the wire"?

I will try this. Can I use any IP on the machine I'm connecting?
