I have two servers currently in the DAG and I'm trying to add a 3rd. I'm getting the error below when trying to add that 3rd server. I'm seeing answers of all kinds on Forums, I've tried changing some NIC properties, I do have the same OS on all 3 servers (Win 2008 Ent.), I can't think of other things I've tried at this moment.. Hopefully someone else has run into this issue and fixed it. Here is the error:
