Hello,
Is there a way to automatically generate a web.config file with allow permissions for a newly created user and deny permissions for everyone else?
Thanks,
Peter Ryan, Jr.

if you touch the web.config dynamically, it will recyle Application pool of site. It will loose all of your Session Data and Cache data if you have any

You can change web.config dynamically..

That is okay if the data is lost but is there a way to make a web.config in a newly created directory with just the text below?

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <system.web>
        <authorization>
          <allow users="CreateUserWizard.UserName"/>
            <deny users="*" />
        </authorization>
    </system.web>
</configuration>
