Getting % cpu used in win2k

HI guys,
is there any way to get the %cpu used from the commandline in windows2k server? I want to run a program on a unix box that will regularily telnet to a load of 2k servers, check how much cpu is being used and update the main database.
Or I can do it the other way around with processes on the win2k reporting to the unix box. But either way, how can I get %cpu used in win2k, in a format useable for a simple c program. ANything similar to PS, or checking the /proc directory?
