I bumped in to this error today when i was about to launch my new OpsMgr12 Installation:
So what could be the reasons for this kind of error?
1. Check firewall settings so that nothing is preventing the connection betwen the target machine.
2. If that’s not the problem, then check if these to services are running “System Center Data Access (OMSDK)” if not try to start it manual. Also check if OpsMgr VSS Writer” Service is running. If not, start it.
3. Check SQL account’s so that everything is ok.
Error: the data access service is either not running or not yet initialized
