(urgent!) Windows Server stuck on a black screen after the "starting windows splash screen"

A HP ProLiant DL380 G7 with Windows Small Business Server 2011 (equal to Windows Server 2008 R2) is stuck on a black screen after the "starting windows splash screen". I'm able to ping the server, able to do some remote management (services, event viewer, ...), can access file shares. But due to some services not starting, other (dependent) services also doesn't start.

So for example, I can't take over the server by RDP, the DHCP service is not running. All services trying to start through remote management give the error "error 1068: the dependency service or group failed to start".

Someone any idea where to start solving this problem?

Rather than troubleshoot with a possibility of a couple day turnaround to a solution ... since this is urgent restore the system from the most recent full backup known to work.  Time to restoration of operation should be less than one hour.

Then do daily full backups (not incremental) of the system.  If/when it stops working again, pull the system drive, restore the last daily full onto a similar drive, take both drives to a third system and compare them to see what happened.

Don't have a valid recent backup which include the whole C: drive. Only system state / OS.

Go through this first:


Then, after waiting an hour to see if it will ever boot or confirm that it will not, you might try the procedure below and see if it applies.


And if it can be restored to operation, then apply the verbose boot option:


Don't have a valid recent backup which include the whole C: drive. Only system state / OS.

Wel then ... consider this a valuable lesson in full daily backup on a critical system, Deo volente at a cost that you can afford.

Thanks all, problem solved.

Managed to restore one part (SOFTWARE hive) of the registry, by restoring it through the command prompt via system repair (booted from another install media).

Well done.  You have dodged a bullet this once but there may be more of them a-comin' as the cause of this issue is unknown.

Suggest that you review your backup scheme and increase to at least every-other-day full backups with a month capacity, and retain at least one full backup per month for the last year.  Disk is cheap but solving problems is expensive.
