SharePoint 2010 RC Installation Changes

As expected, the SharePoint 2010 GUI installer was updated again in RC.  So, for those of us that had been installing on a DC box, there was a new surprise.  When installing on a DC, the SharePoint 2010 RC bits detect this and only allow StandAlone Install.  So, all services are configured for you using Local System or Network Service.  Likely, you want a farm install and not standalone. 

I soon came across this posting that had the issue and resolution.  This worked for me and should for the rest of us that need a single fully featured server for demos, prototyping, etc.

Solution with config.xml settings
