We have 3 blade servers in which I am planning to install the virtual infrastructure. In blade 1 I plan to install Virtual DC which will be migrated from win 2003 DC to win 2008 R2, than file server will be migrated and DFS installed. I will include here also Virtual Print server, virtual Wsus server, Virtual Spiceworks server.
In two other blades I am planing to install a fail over clustering feature and put SQL 2008 server, Sharepoint 2010 Server, Email server and a server for backup and testing purposes.
Since I read a lot of recommendations that Clusters need a separate domain in order to be authenticated, and they need a physical DC .
My question is can I add e second domain controller in win 2003 with a different domain name which will be the demoted physical DC in win 2003 just for cluster authentication. I will reinstall the win 2003 operating system and than add it as a second domain controller. Is this OK. Did anybody tried this scenario?
