I am attempting to install WS2003 SP1 and SBS2003 SP1. When I get to step #2 of the 5 steps detailed on this site, install Sharepoint Services 2.0 SP1 I get an error and it doesn't install. I went past it, successfully installed Exchange Server 2003 SP1, but when I try to install SBS2003 SP1 I get an error and it doesn't install. Suspecting there may be a Sharepoinit Services issue since that SP1 didn't seem to install correctly I thought it would be adviseable to reinstall my Intranet. When I go to Control Panel>Add/Remove Programs>Windows Small Business Server 2003>Change/Remove I get an error which says "You must configure your operating system to proceed with the installation." Typically instead of that warning, I would have expected to get the Component Selection list but instead I am prompted to configure the operating system. Can I just let the operating system configuration proceed without any major adverse effect? It is posible I removed or changed a required component when Iwas trying to figure out what with wrong in an earlier failed attempt at installing WS2003 SP2, which I am still trying to recover from. I have a small single server LAN with a couple of workstations which I administer myself. I have a full NTbackup which is saved to tape every night.
