Just got off a 2 hour call from Microsoft. Heres the deal. There is a hotfix that SBS applies during the registering components phase. The first one is KB822742. For some reason this hotfix hangs the install. If you are running the SBS install and get to this point hit shift F10 on the keyboard. This brings up a command prompt. Type in taskmgr and you will get the Task Manager. End the hotfix by right clicking and ending process. The install should continue. We tried to figure out what this hotfix is for but couldn't find it on the net. Its some kind of critical security update that comes on the CD. Anyway, killing this process lets the install proceed. I'm not sure if I'm going to apply the hotfix at the end of the install or not. Probably just leave it off for now.
