Dependency service or group failed to start
I got following error when I tried to start the SQL Server service:
My SQL service is running on my domain user account, and this is the reason I got the error. To be able to run any services using a domain account, the Netlogon service must be started.
For some reason (I blame the windows updates that were installed) this services startup type was changed to Disabled. Reconfiguring the Netlogon service to automatic and start the service solved the problem.
Netlogon: Maintains a secure channel between this computer and the domain controller for authenticating users
