I have a Dell T100 Server with Windows 2003 R2 server OS. I want to repair the operating system by booting on the windows CD and doing a Repair to reload damaged files. The server was shipped by request with 2003 R2 which was too old then so the CD and license with it is for 2008 R2 server.
I tried to order a disk from Dell and then Microsoft but they cannot provide because the OS is too old and not supported. They apparently don't have any stock of these.
I have a 2003 R2 server disk from another customer of mine. Can I run the repair using that disk and then should the Product Key on the sticker on the repaired computer work? Failing that can I use the other customers Product Key to repair the OS? They are both valid installations and I just need to repair the OS.
