The Network admin guys did some windows patch update on the WSS v3 - OS - Windows 2003 server
Until after logging on to the site tried doing some searching and Oops no search results returned 
- So i taught sure the services has stopped or i have to restart the service but after checking the services on the OS and the
Sharepoint Central Admin everything thing looks ok. Well its time to look for a fix
So what next and where to start .
First was this Microsoft Support site: but didn't solve the problem.
They were also solutions saying i should restart the search service.But also didn't work. Some posts said it worked for them so its worth trying
- I also made sure i went to my Sql Server 2005 > Security > Logins > Made sure my Service account and the content access (domain accts e.g mydomain\WSSSearch )have min dbreader access to the WSS_Content and WSS_Search database.Still no luck
- Until i found this Ivans' blog(thx Ivan) that recomended changing the Service Account username and password to match the Content Access Account details from the Sharepoint Central Admin > Opertations > Services on Server. Click OK on the bottom of the page and wait five minutes. and bingo it worked
Keep Sharepointing
