Oh man, I think we just don't talk the same language. For me you still haven't answered the basic question of what is the relationship between the IIS server that will run your ASP and the folder you want to search.
You say they want you to talk directly to aaa06. If that's not on the same server that will be running your ASP then you need to do some work to allow your ASP access.
I've just posted this link to a similar (well it sounds similar to me anyway ;)) question. Go to
http://support.microsoft.com and look for Microsoft Knowledge Base Article 197964 which is entitled "PRB: Cannot Access Remote Files with the FileSystemObject". See if the symptoms it describes are what you're experiencing.
