Can't get mysql connection either

I am a  newcomer to the list and php/mysql, and fairly novice at programming. 

Something broke my functioning win32 (XP sp2) apache2.2/php5/mysql 5.0 installation running on localhost.

Two possibilities: 
--rebooting to install latest MS security patch 
--placing into a working script dummy code for logging into mysql on web host account; I thought it was commented-out, but?.

The first symptom of the problem was an  “undefined function” error on a call to mysq from that previously working script. All scripts with calls to mysql functions seem to be affected. 

At first, I could still access mysql from the command line. Now, I get error 2013(hy000) “connection was lost during query.”  I can’t connect to 3066 via telnet either. Phpinfo() does not indicate mysql is loaded.

I’ve studied everything and it seems in order: Apache & Mysql running as services. Ini files all where they are supposed to be and say what they should. Various components (dlls, eg) are where they belong. Windows firewall “off”; Norton set to allow 3306.

I have reviewed on-line documentation and FAQ’s, and am stumped. Can anyone help?

Thanks,
P Baxter
