After installing SP3 for WSS 3.0 the search function no longer returned results and the 2436 errors started. The event log (sans server and DB name) follows, but I have tried the following:
Changing accounts under search service for content and search per (http://support.microsoft.com/default.aspx?scid=kb;en-us;927012
) to read enabled users (same and different) for the content and search databases. Restarting the the service. Stopping and creating a new search database. Not to mention about 4 or 5 (blocked items, etc.) other suggested changes including AAM. So what do I try next? I can't help, but think this is something related to SP3 as it had been working some time (1+ years) and the installation is per MS recommendations for a parallel install of WSS 2 and 3 on SBS2003.
