This is not an Umbraco issue, but rather a Microsoft one.
I am trying to run Umbraco 4.7 on IIS 6 as a ASP.NET 4.0 app. Any website created on my IIS 6 and ran as a 4.0 app cannot resolve a default page. However, this issue is intermittent. It displays a 404 error or sometimes the error refers to eurl.axd. I found a few articles:

Cannot find a fix. The ASP.NET 2.0 sites on my server run fine.
Any help would be greatly appreciated. Thanks in advance.
Did you try the staps: http://johan.driessen.se/posts/getting-an-asp.net-4-application-to-work-on-iis6
Is your application pool a ".NET 4.0" pool?
What user is your apppool running?

Did you set the necessary permissions for the "NETWORK SERVICE"?
If not refer the following URL

Reregistering ASP.Net 4.0 in IIS may help.
