hey guys, on my c: partition I am running server 2003, with firstdefense isr, and its working great, no complaints. for base imaging I am using acronis. I decided to install windows xp on a seperate partition, for games mainly, rather than from within firstdefense, as sometimes it's advantageous to actually have that true second partition. so now that I have windows xp installed, like with server 2003, I am looking for that 2nd layer of protection, only I cant use firstdefense with both server 2003 and windows xp. neither shadowuser or deepfreeze run on my system for some reason. can anyone recommend a good virtualization program that compliments acronis well, which doesnt modify the master boot record? t.i.a.
