OK I ran into some trouble installing these last night.
Basically I read the instructions that you have to install the 5 different packages before installing SBS Sp1.
I looked at the system properties page to see if it was in fact installed and it didnt say Server 2003 sp1. So I knew I had to start from square 1.
Before I did I looked into add/remove programs and there was Server 2003 SP1 installed (it only said 29mb's)
So I started to install and it ran through fine all the way until the end when it bombed out failed :3010 in the update log.
Researching found http://support.microsoft.com/kb/928595
This was no help. Basically I restarted the server and left it, all services are running fine.
I now look at system properties and it shows SP1 installed.
Should I move on to the next step and install the sharepoint update and so on?
