Thanks for the reply
I've tried starting the ser vice with all types of user accounts. I've also give these accounts full security access to the database
I've disabled all services and rebooted. I then tried to start the service and it still fails
I have also used a backup database and it still fails
I have installed safeboot administrator on another machine and replaced the servnt.exe - made no difference
Disabled all AV services and tried again
any other ideas?
