OK, I had to backtrack a little on installing Team System.
* I reinstalled SQL Server 2005 to include all components, including Reporting Services. I'm not sure how this matters, but the instructions say to include all components.
* I removed DNS Server, DHCP Server and Active Directory Server as roles from the application server. This is because ADAM was refusing to install on the indicated ports. I may have to turn the database server into an Active Directory Server.
Note: After reading Darren J's blog again, I see that I should let ADAM use the other port settings instead of worrying about the exact numbers.
* So, I reinstalled a primary Active Directory domain and DNS.
* I added the database server to the domain.
* I finished installing ADAM. No issues.
* I installed .NET Framework 2.0 Beta.
