SYMPTOMS
When using IIS IP and Domain Restrictions to deny clients by a specific domain name, a client with an IP address that IIS cannot resolve will still be allowed to connect. The client may request content over this connection for the duration of the session. If the client makes a request over a different connection, it will be properly denied, and will receive a 403 error that the IP address is not allowed.
