Consider the following scenario:
In this scenario, when the installation program validates the user account, the installation wizard fails.
- You have a perimeter network (also known as a DMZ, demilitarized zone, and a screened subnet) that only has a read-only domain controller (RODC) available.
- You have a member server in the perimeter network.
- You try to install Microsoft SQL Server 2008 R2 on the member server, and you use an Active Directory service account for the SQL Server service.
In this scenario, when the installation program validates the user account, the installation wizard fails.
