How to List SharePoint 2003 Site Administrators

Question

Hi,

I am SharePoint 2003 newbie. My organization has a approximately 75 individual SharePoint sites (for departments and teams). Most sites have unique permissions.

I would like to build a .NET tool that would either take the URL of a SP site as input and have the app return the name of all users that have Administrator rights to the given site, OR some mass listing displaying each site and it's associated Administrator(s). Is there any way to do either of these?

Please help!!

Thanks, -Joe
