Hello,
I created two hyper-v vm's for test. Both are in the private vm switch so they can not talk to any other external network.
One Server # 1 - I set the IP & Subnet for 192.168.0.1 with no DNS / Gateway. I installed SQL on this server and restored a copy of production SQL SEPM database.
One Server # 2 - I set the IP & subnet for 192.168.0.2 with no DNS / Gateway. I Installed SEPM 12.1.5 on this server and configured it use Server # 1 as the backen database.
On an additional 3rd VM - I have a SEP client on Windows Seven that is talking to Server # 2. IP here is 192.168.0.3 with no DNS / Gateway.
Now I log in to Server #2 SEPM, and I see that almost all (30k) clients are noted in SEPM as online mirroring the produciton DB, I would expect all machines (sep clients) to go offline as the server is unable to talk to those client. This is not happening though and all client show online after 3 days of this setup. Our heartbeat is set to 2 hours.
Why are the clients not showing as offline? The only client online should be the 3rd VM. Any ideas?
