I have a WSS v3 server with SP1 and i was looking at upgrading the search to MS search express 2008. So i taught let me upgrade it to SP2. Donwloaded the trouble and then installed it and it went like a breeze. Everything went ok only i didn't test whether the search was working(MY FAULT -trusted MS) After a while i got an email from a user saying search isn't working.And i taught i'll just restart the search service and it will be fine.But that didn't do the trick Look a the ULS logs and Event Viewer ......
Just to let everyone know that
