Why does a cluster install of SQL2005 require access to a domain group and what is the purpose of having to create a domain group for the cluster installation Other than the blurb mentioned in BOL I'm having a hard time finding any information out about this requirement.
From BOL: How to create a failover cluster.
Section 18: On the Domain Groups for Clustered Services page, provide a DomainName\GroupName for each clustered service being installed: the SQL Server service, SQL Server Agent service, Analysis Services service, and Full-Text Search service must run as domain accounts that are members of the built-in administrators group on each node of the cluster. To proceed, click Next. For more information, see Domain Groups for Clustered Services.
Cluster installation & Domain Group requirements...

The purpose for domain groups in cluster installation is security consideration. As SQL Server service accounts in a local group can be changed or removed after SQL Server 2005 is installed. Then the security setting like ACL will be lost. That is why domain group\account is introduced.

Ok, that's kind of what I thought it was for.
Is there any way to change the group after installation Can I just move the account to another group and be done with it Or is there somewhere (in SQL Server) that I need to update the group if we desire to change groups
