WampServer

Hello, i have installed WAMP server (on windows XP and windows 7) and I have the same error,
In local mode, it works fine...but..if I modify the config.inc.file to another host: (by IP or FQDM) the phpmyadmin login page say "error 2000 mysql denied connextion".
I looking mysql (remote) logs, and NEVER i saw any connection attempt.

Now. I installed PhpMyAdmin in my LinuxBox, i modified the same file, and works FINE!!....

Linux OK
Windows BAD!..

any ideas?

thanks
