IIS_IUSRS group is not found in Windows 7 laptop

Question

I have 500 error when debug an asp.net application on my Windows 7 laptop. It looks like a permission problem.

Therefore I want to give the permission to the corresponding folder. I tried to add IIS_IUSRS to the group. But I can't add it because it doesn't exist. See the image below please.

EDIT:

I checked the user groups. It is there

Answer 1

IIS_USRS is local group added with IIS 7 release. It isn't available on active directory so while searching it location should be selected as local machine name in "From this location" field. You should be able to find "IIS_USRS" group under your local machine.
