make permission in IIS7

I have IIS7, web app is written on ASP.NET 1.1. I need to see files and folders in the browser when adress as like http://localhost/MyProject. Have to make permission for this? or... so, help m开发者_开发百科e please

UPD. Yes I know it. But when I did this I have this error

Line 215:       </root>
Line 216:   </log4net>
Line 217:    <system.webServer>
Line 218:        <directoryBrowse enabled="false" />
Line 219:    </system.webServer>

After That(I read about this pronlrm on interner http://blogs.iis.net/bills/archive/2008/06/02/installing-asp-net-1-1-with-iis7-on-vista-and-windows-2008.aspx) I have added to (%windir%\Microsoft.NET\Framework\v1.1.4322\config\machine.config) this . And the error gone.But I still can not browse files.

From IIS click on your website. Under IIS go to Directory Browsing and click Enable. See a more complete description on MSDN.
