did you activate the product?

Or is this server NOT a domain controller?

You may have to repair the installation as mentioned

1.The most of common problem is that the your computer is infected from worm/virus the only way is format your system and reinstall the OS because the administrator profile is damage so you are getting this error if you login another user then you can not. Most of time repaire tool not work . may be your luck but you have to reinstall it its better idea.

2.back up the data try safe mode, if unable to get in safe mode > do a parallel back up the data and then format
reinstall, for the screen shots of parallel.

but did you set it up as a domain controller?  if you don't do this, the product activation message will appear.

With a SBS server is automatically becomes a domain controller
I think this message means exactly what it says.  Somehow your Windows system files have been corrupted.  Possibly due to a virus/trojan/worm but IMHO more likely due to a hardware failure of some sort.

As a first step, I'd follow the message recommendation and boot into recovery mode and to a REPAIR.  This may get the system up again and you can inspect the event logs and see if there has been a hardware event.

It was a worm apparantly.

The resolution was to change the attributes to the two following folders. (they were set to read only) - I managed to change them from SAFEMODE


After rebooting the server started up and I ran a virus scan and removed all infections.

One thing I have noticed if anyone can help, is that we have SAP Business One installed and I need to regenerate the License Key, but the HARDWARE KEY isnt showing up - does anyone have any ideas?
