Answer 1

Looks like the user account you're using for your app pool doesn't have rights to the web site directory, so it can't read config from there. Check the app pool and see what user it is configured to run as. Check the directory and see if that user has appropriate rights to it. While you're at it, check the event log and see if IIS logged any more detailed diagnostic information there.

Check ASP.NET Installed or Not From Windows Component tool

For others out there, I got a similar error message due to trying to run a .Net 4 app in a .Net 2 app pool. Changing the .Net FX version for the app pool fixed it for me.

I was having a similar error installing php 5.3.3 with the Error Code 0x80070020 with a direction to a few lines in web.config in my www root directory (not the standard root directory).

The solution, while crude, worked perfectly. I simply deleted the web.config file and now everything works. I spent HOURS trying other solutions to no avail.

If anyone thinks this was stupid, please let me know. If anyone else has spent the same amount of time pulling out hair, try it and see (after backing up the file of course)

We have two site (live and test) on same server talking to same DB with app pool identity. Still we can access test site fine but Live shows 500.19 - Internal server Error.

I swap directory of both sites, and they works fine. Swap application pool identity. But no success. Any Ideas?
