Hi,

In my environment, I add another SCOM 2012 R2 to existing management group. (old SCOM is 2012 R2 ->SCOM1)

We have one SMS provider in SCOM1, after added SCOM2 in the Event Viewer we have Event ID 21400. I googled and in the Administration tab for Notification Pool and AD Assignment Pool change the member ship form Automatic to Manual and remove SCOM2 from those, finally Error 21400 is resolved. But every hours in the active alerts shows Resource Pool Heartbeat Failure from All Management Server Resource Pool Watcher.

Another problem is :

in the active alerts select a critical or warning or information in the Alert Details shows in just SCOM2:

This Page cant be displayed

• Make sure the web address is correct.
• Look for the page with your search engine.
• Refresh the page in a few minutes.

thanks
