I have a Exchang Server DAG on Windows 2008 R2 cluster server. By default if you configure Exchange DAG, the windows cluster name and DAG name will be identical. In my case for some how the name windows cluster name is different than Exchange DAG name. Now I am having problem in Symantec Exchange Backup Exec for pusing Agent on DAG. I want to rename Windows Cluster name as Exchange DAG Name. Can we rename Windows Cluster Name in DAG environmen easily? Are their any options or tools for it? Thanks,.
