We have DAG with 3 Exchange servers. Today morning one server has been affected by Ransomware and we have shutdown the server immeditialy and we are not going to on the server again.
Now what should we need to do?
Case1 : Do we need to build the new server again and will install the Exchange on it. After it we will try to remove the server? If this is best approach then can you please let us know any best method to remove the server from the DAG and then from Exchange environment?
Case 2: Can we restore the server from snapshot or from backup software? Is it fine to restore the server from backup in DAG environment? As I have heared or read somewhere that resote of server from snapshot can be catastrophic. Please comment.
