I was in the process of successfully installing SBS 2003 Premium when I discovered I was missing the 3rd disc. It is required to install some of the server tools etc. I have called MS and they were no help since this is an OEM copy they gave me the run around. I have a friend that has SBS 2003 R2, can I use his disc 3 to complete my SBS Premium installation? Any help would be greatly appreciated, thanks!
