Problem installing Zenworks 11 SP2

Hello,

I'm trying to install Zenworks 11 SP2 on my Zenworks 11.0 server.

During the setup I selected the Embedded/OEM Sybase SQL server. However 2 screens later I am asked to specifiy the external database server.
I entered the local servername, but in the next screen I have to enter the database name and credentials and also the servername again.

I've tried everything, but it keeps saying that there was an error connecting to the database.

What am I doing wrong? I 'm not even sure what the name of the database is of where I can verify the name.
Why can't I just browse for the correct database?

Thanks
