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
