Description:
aspnet_wp.exe could not be started. The error code for the failure is C0000005. This error can be caused when the worker process account has insufficient rights to read the .NET Framework files. Please ensure that the .NET Framework is correctly installed and that the ACLs on the installation directory allow access to the configured account.
Security log
in security logs I got failure audit for System and Network services accounts.

Use ASP.NET IIS Registration Tool (Aspnet_regiis.exe) to uninstall and reinstall :

I did following steps:
1. Uninstall Symantec Endpoint Protection (SEP 11.0.5).
2. Restart the computer.
3. Check ASPNET user is not locked by right clicking on my computer and manage > Local users and
group > Users.
4. Open Visual Studio 2005 command prompt.
5. Type aspnet_regiis I and enter, it will install asp 2.0
6. Close the Visual Studio 2005 command prompt.
7. Open normal command prompt and restart the IIS by typing iisreset in run menu.
So my conclusion is, this problem occurs due to Symantec Endpoint Protection 11.0.5.
But i am still doing some R&D.
I have engaged with Symantec on this same issue. It is only related to Symantec Endpoint Protection version RU 5. If you remove the Application and DEvice Control from the Firewall module, then you should be fine, temporarily. This issue is already resolved in RU 6, which has entered Alpha testing.
SEP 11 RU6 is still a couple months away from being released. This is the only ETA I have currently.
In the mean time, I had to remove this policy for all my machines in my network to avoid more issues. Some people don't think it has to do with Antivirus and start troubleshooting an issue with IIS, ASP.net and sometimes they mess things up when they were not even broken.
There is a file that prevent the launching of ASP.net service, thus not allowing ASP.NET .net version 2 only, applications, to work.
Hope this helps (late, but sure)
Regards,
I had the exact same problem although other users with similar builds (or so I thought) had no issues. To resolve my problem I upgraded Symantec Endpoint Protection to RU6a and the ran aspnet_regiis.exe for 2.0. Dot .Net 2005 projects now run fine.
However, just recently some of my colleagues upgraded their SQL Client tools to 2008 R2 which also installed the .Net Framework 3.5. After this they started experiencing the same problems which was resolved by upgrading to RU6a.

I guess you install iis and then .net framework. Then recreate virtual directory for your website/webapplication. Hopefully this should go away. WHen you'll recreate virtual directory, .net 2.0 will be configured with your site.
