Hi folks,

I have two exchange servers that are in DAG. One of them is dead.

I'm planning to setup another one, add it to the DAG and then remove the dead one from the DAG and the AD environment.

Anything special I need to have in mind when doing this or do you reccomend another way?

Thanks in advanced.

I would rather run a recoverserver to recover old server and recover exchange config from AD.
