[Skunkworks] DC storage challenges

Hi Skunks I have this Domain Controller that has serious space issues on drive C. Apparently, other drives have space that I would love to borrow from but the Disk Management wont shrink/extend. I have taken the risk to pop in Mepis Linux Live CD wishing it would run in RAM and give me GParted but i dont think Win Server was made like that. Any ideas would be appreciated, even the most obvious, I don't mind running through them with a fresh pair of eyes Running Win 2008 Server Standard
