PHP On Solaris 9 - MySQL Problem

Hey guys, I'm back again after trying many more things to solve this problem. If you weren't following the previous thread with Adam, I moved my site from a single development machine to the production environment which consists of a separate webserver and dbserver. At that point, PHP could no longer connect to MySQL. I've started up MySQL on the webserver now and PHP can connect to it. Something is preventing PHP from connecting to MySQL on the dbserver though and I have no clue what. I've connected to it via the mysql client as both root and the webserver user from the webserver. I've reinstalled the MySQL libraries and recompiled PHP on the webserver, but no matter what, it still won't connect to the MySQL on the dbserver. Is there some security function in PHP preventing this? Safe_mode is off, but could there be something else? Thanks, Cameron
