Hi,

You must ensure that name resolution works perfectly in your environment.

One of your server tries to join another Exchange server names ORION2 and can not reach or connect to it.
Make sure that your Exchange servers are well registered in DNS with their correct IP address.
If your trying to build a NLB cluster and then your servers have multiple NICs, one of these  NICs should be dedicated to NLB for CAS access with a IP address common to both server. In this case, you SHOULD NOT have the server registered in DNS with this common IP address !
Other Exchange server must join ORION2 through its non-NLB NIC and IP address.
So check in DNS if you see ORION2 registered with its NLB IP addres and if yes you must disable dynamic DNS registering on this NIC and remove the DNS record from DNS.

HAve a good day

Hi again,

By the way, personnally, and as I think it's a Microsoft "Best Practice", when I build a NLB cluster I always disable DNS dynamic registering on all NICs and I manually create required DNS records.

Doing like this is more "clear" and avoid some strange behaviors.


And thanks a lto for the points ;)

Have a good day
