don't wait for Windows to notify you, it's just a polite message.
Out of curiosity, were patches applied recently to Windows Server ? You may get some clues in the Windows log, you will at least get some more information.
One other thing to check: are there plug-ins trying lo load when FMPA starts ?
Hi, there are no plugins loaded (we can't check with preferences since starting won't come that far). It might have been a (fatal) windows patch, since we haven't changed or Updated FileMaker. It worked properly before.
Did you check Windows logs ?
