Hi , We have a CRM2k11 deployment on windows 2k8 r2 with IIS7.5 we are experiencing an issue where we cannot login to CRM when connecting directly from the local machine via DNS url (e.g crm.domain.com). This happens on both Http and Https protocols, and we can successfully connect from an external source on our lan using the same DNS url. When we enter the url on the local server, it gives us the username and password prompt multiple times until a 401 error is presented. We have tested integrated authentication and ensured that kernal mode auth is on. If we log in locally on the crm server machine and use the fqdn it does work. This is NOT a DNS resolution problem as it can resolve from all sides. Is there some settings with the bindings that need to be changed? Thanks
