Error thrown on machine discovery.

Hi All,

I'm a little new to SCOM so thanks for any help.  I've got MSSQL Server 2012 on Server 2012.  My SCOM server has been working for several days now and I tried to add a computer this morning via the Discovery Wizard and now I'm getting this error:

Can not connect to the Health Service running on XXXXXX, please make sure that the health service is running, See inner exception for details.

I tried starting the HealthService and when I do I see this in the Event Viewer:

HealthService (4704) Health Service Store: The database engine stopped the instance (0). 

SQL Server appears to be running so I'm not sure why it's killing the service.

Thanks.
