php_mysql library

[John Ertel <ertel@xxxxxxxxx>]

hi there -- i need help badly -- i finally got the mysql library for 
php to work but now it will work for a few page loads and then all 
mysql/php pages produce a web server 500 error -- this is unrelated 
to programming as it doesn't matter what php script is running -- 
even the phpmyadmin panel.  If I restart the web service, it runs 
fine a few pages then the 500 error.  This is under windows server 
2003 and IIS.  Help!  there weren't really installation instructions 
with the library so i'm guessing maybe i goofed up the installation somehow?
