After deleting and recreating a web application, SSP administration is gone

I'm currently trying to work with MOSS 2007.

I tried some stuff out and messed the web application up. So I deleted the web application, created a new one and worked with it. I used the SSP "SharedServices1" for this.

After 2 days of implementing some stuff, I realized that I need to configure automatic AD import, what you do in the configuration of the SSP. But in the central administration, the button for accessing and deleting the SSP is grayed out. Most likely because I deleted the web application where the administration of the SSP was running on.

What should I do now Is there a way to recreate the administration page without loosing all data of the web application and the site collections in there

I looked at what I have to enter into the form "Creating a new SSP" and am a bit weird: What would I enter into the account under that the SSP service is running
