SQL Server Reporting Services SharePoint Set Server Defaults

Trying to configure Reporting Services 2005 with an existing SharePoint site is painful to say the least. One of the pains was the error below when clicking on "Set Server Defaults" under Application Management within Central Admin. After searching through some forums, I found a solution

I when to the Operations tab in Central Admin and clicked "Alternate access mappings" and then selected the Central Admin collection and removed all mappings except for the default one. Then went back to "Set Server Defaults" and the error went away. I could then go back and add my mappings back in and the error still did not show.

I can't explain and really don't want to know the internal workings of Reporting Services with SharePoint but the above solution worked for me, hope it works for you too.
