For SQL Server cluster installation on SQL 2005 and SQL 2008 it requires to create a active directory Domain Group. The question here is, 1. Do we have to create the active directory domain group for each cluster instance? Can we share this account with other SQL Server cluster installation? 2. Does SQL Server Service account and SQL DBA windows account need to be part of Windows domain account? http://support.microsoft.com/kb/915846
Welcome to the forums. Q1) No if all of those NODES and instances are on same domain, then 1 group is sufficient Q2) http://sqlserver-qa.net/blogs/tools...nd-the-sql-server-service-domain-account.aspx
