Windows Server 2008 R2 64-bit installation, IIS 7.5. My question: why will IIS 7.5 allow the sites to work with the IUSR account only, or with the Users group which includes the IUSR account, but not with the IIS_IUSRS group which also includes the IUSR account?
And, is there any way to fix that? Unless the IUSR account is given access to the Inetpub site directories specifically, or the Users group is allowed access, the websites return a 401.3-Unauthorized error. I added the IUSR account to the IIS_IUSRS group,
which I would prefer to use, and added that group to the permissions of Inetpub directories. But, that doesn't work, same Unauthorized error. I added the Users group back to the permissions temporarily for testing, and that allows the sites to work normally.
I am running other Server 2008 servers, and using the IIS_IUSRS group functions normally. Those are not R2 installations, however, and so not IIS 7.5. Any ideas?
