Read Only

I am tryinng to learn ASP.NEt using Visual Studio 2005. Having a hard time
getting started. Whenever I try to to use a browser to go to a page, I have
created, via localhost, I get an error message "JOELOFFICE\ASPNET DOES NOT
HAVE WRITE ACCESS TO c:|windows|MICROSOFT.NET\Framework\v2.0.50727\Temporary
ASP.NET files."

So I go to JOELOFFICE\ASPNET in Windows Explorer, right click, select
properties and remove the green box from the Read Only Attribute, then select
the radio button "Apply to all subfolders", click Apply, OK - OK. Then when
I go in to properties to see if the new setting are still as I just set them
I finf the green box in the Read Only Attribute is still there. Yes I have
tried restarting my machine. I can not get Read Only Attribute deselected in
those Properties windows or and others. Any help would be much appreaciated.
I am getting a little frusterated.

Thank you, Joel
