OK, so I've been trying to install beta 1 of the Office 12 Server, with limited success.  My good friend Mauro Cardarelli warned me about installing this server on a domain controller, so I've create a virtual environment consisting of three virtual machines.  One is a domain controller, and the other two are member servers.  One member server is a SQL Server, and the second member server will be my Office 12 server ...

I have all three VMs up and running, and the member servers have been joined to the domain.  Once I got all the prerequisites installed on the Office 12 server (.NET Framework 2.0, ASP.NET, WWF 3.0, etc.) I installed the Office 12 server.  The installation completed, and life appeared to be good.  However, when I ran the SharePoint Products and Technologies Configuration Wizard, configuration task 5 of 9 fails with a "Failure to Register SharePoint Services" message.  Additional exception information is that "This access control list is not in canonical form and therefore cannot be modified." ...

Has anyone gotten this to work?
