Update 2... Installing SP1 (and all its requirements listed above) on SBS Premium Edition... and... well that list is not complete

Premium Edition includes SQL Server 2000, and before you can install the SBS SP1 it scans the server and tells you you have to install at least SP3 for SQL2000. I installed SP4. Not that its a bad thing to install this patch, but it adds another 70mb to the download list.

Anyway, the downloads are now pushing 1GB
