The ability to search for anything on one of my Windows 2008 R2 servers has, for reasons unknown, stopped working.
For example I can't search for anything via the Start Menu:
Clicking "See more results" displays this error dialogue:
I can't search for files or folders in Explorer (there's no network drives, just a
C: drive). All that happens is the search term is displayed in the explorer window title bar (see red highlights):
And most annoyingly, I also can't search for specific installed updates. Again all that happens is the search term is repeated in the window title bar:
This isn't because the Windows Search feature isn't installed. My other Windows 2008 R2 servers don't have that installed either but their search widgets work just fine.
I did bump into this hotfix:
But when I try to install it I'm told that:
The update is not applicable to your computer.
How do I get search working again on this server?
