Status Message Unable to fetch Managed Object details for the object : xxx

Hello,

we use OpManager Version 8720.

Today we added a VMWare ESxi 4 Server to OpManager.
After changing the IP-Adresses of the Virtual-Machines running on that VMWare server, we are not able to see the details of any of those virtual-machines. We always got the Message: Unable to fetch Managed Object details for the objec: xxx

Even deleting and readding the VMWare-Server and its Virtual-Machines did not help.
Our Database is on Microsoft SQL Server and we run DBRepair without any success.

Can you please help?

Thanks in advance
