I'm trying to set up my first DAG.

Installed all pre-req's
Added replication NICS, tested ping
Gave Exchange Trusted Subsystem permissions to member server

DAG is created fine. When I add 1 Exchange server I get the error:

Summary: 1 item(s). 0 succeeded, 1 failed.
Elapsed time: 00:00:06


ECS-EX
Failed

the error is very clear

 Error: Computer account 'DAG1' couldn't be validated by user 'NT AUTHORITY\SYSTEM'. Error: An attempt to use the specified cluster name failed because an enabled computer object with the given name already exists in the domain

it looks like you already have a computer account called DAG1,

try deleting your DAG and create another one with a totally different name and try again
