Zabbix on Centos Database on Windows Server w MySQL

[knix]

Hello Zabbix-Users,

I have a problem to use Zabbix on a CentOS 5 and an Mysql on a Windows Server 2003 SP2 with Mysql.
I currently have this setup, i moved from Mysql Database on CentOS 5 to Windows Mysql,
and if a add a new machine to Monitor the Availability is Unknown. Is this a Bug?
Is there a difference between Mysql for Linux and Mysql for Windows?

Regards,
