We have a server running Windows Server 2003 which was OEM pre-installed.
We also have volume licence media for Server 2003 R2, is there any way to install the R2 components from disc 2 on this server without a re-install? I tried previously but the product key is rejected. The product key is definitely correct.
I'd like to avoid a full backup/re-install/restore if possible.
Licensing is a non-issue in this instance.
