Correct ´my.ini (no replies)

Hi all.

I have some problems with my server running perfect, so im trying to figure where the problem is, so I would start see if MySQL is setup proberly on my server.

Main problem is, time, when I try to example: install a php script with MySQL, then when writing the files/database I have to wait 4-5 minuts before I click Go, else its not doing anything than giving an error.
Its like something is blocking!

Windows 2008 (IIS7) 64bit 8GB Ram.
Server is running Web/Mail/other stuff.
All around server, but primary webserver running sites using PHP 5.1.14 and MySQL 5.1.
WinCache.Extensions disable

Is my.ini looking ok with the about setup, or does it need some tweaks?

InnoDB is disabled.
