Data Acces Service could not start

Question

Hi everyone,
Completely accidentally, putting manually Agent Control Panel settings on the management server then we have restarted the Microsoft monitoring agent service.
After having realizing our mistake, we have removed all these settings(it should be empty in the management server), but then some problems occurred on the server and data access service does not start again. There are 2 management servers at the environment
and we are having the same problem on both servers.
For example, the following event is seen on the event viewer, i know the description is not normal.
The System Center Data Access service failed due to an unhandled exception.
The service will attempt to restart.
Exception:
Microsoft.EnterpriseManagement.ConfigurationReaderException: Feature of type 'Microsoft.EnterpriseManagement.ServiceDataLayer.IDBVersionCheckFeature, Microsoft.EnterpriseManagement.DataAccessService.OperationsManager, Version=7.0.5000.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
cannot be added to the container. ---> System.IndexOutOfRangeException: Index was outside the bounds of the array.

   at System.Threading.ThreadHelper.ThreadStart(Object obj)
Also, when we control, at the registry   [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Server Management Groups] keys are dissapearing!
When we created the keys manually, data access service is starting and console is opening. But when we restart either Microsoft monitoring agent service or the server  these keys are dissapearing again.
Any help!

Hi Yan,
I also continued to analyze at the lab environment. But, the following key cannot seem on the new established server:
(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Agent Management Groups)
Are you sure that you have it? This key must not be seen on the management servers.
By deleteing this key (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\Agent Management Groups) and HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HealthService\Parameters\management Groups\  for group (was empty) copying
the keys out of the working management servers, I realized that problem is over.
Thanks
