UAC/Permissions annoyance

I'm using Windows 2008 R2 as a webserer, the machine is part of a domain...

When the directory for each website is provisioned, it's setup with the
following permissions:

IIS APPPOOL\\<site> - READ
SYSTEM - FULL
Administrators - FULL

The website works fine, however whenever I attempt to browse to a newly
created folder in Windows Explorer I get the following:


"You don't currently have permissions to access this folder.

Click Continue to permanently get access to this folder. "


I've tried the following:

i) Running Explorer as Administrator
ii) Adding my domain user to a custom local group and adding FULL
permissions to that folder

Neither got rid of the prompt..

What I'd really like to happen is either no prompt at all, or forcing the
UAC confirmation prompt (UAC is turned on). I really don't want to have
every user receive this prompt, when there could be thousands of folders,
and the ACL's polluted with all this additional rubbish.

Any ideas?
