What operating system is on the PC restore CD. I have the first Home Server. I would mainly like to know if it is Windows XP or Vista. I need to know if it is still supported.

I don't have the original package or case anymore. The server was released in late 2007. I know the main server itself is SBS 2003, but the Home PC OS (I don't have a free PC to try it on). I'm not sure of.
