CertSvc is not starting due to database restore operation

Hi, 

Whenever I tried to start the certificate service I get the following error, 
Active Directory Certificate Services did not start: Unable to initialize the database connection for SubCA01.  Certificate service has been suspended for a database restore operation. 0x80094006 (-2146877434).

I did the following to fix the issue;
1.Repair using ESENTUTL /p “SubCA01.edb” -> Successfull 
2.Recovery using ESENTUTL /r edb -> Successfull 
3.Integrity check using  ESENTUTL /g “SubCA01.edb” -> Successfull 

But still when i tried to start the service i get the above error.

I am not sure which process has initiated a restore operation as mentioned in the alert. Any ideas how i can fix this ? (I tried restarting the server, still the same)

Thank you
