Re-partition Windows Server 2003 harddrive

I need to re-partition the harddrive of a Server 2003 box, preferably without re-formatting. It is the DC, file server, print server, and application server. A previous administrator divided the drive into multiple partitions, the C partition being one of the smallest. I have access to Partition Magic 8, but that will not install on the server. I’ve tried to wait for a replacement from corporate, but I’m running out of time and space.
