I have a site hosted on a Windows Server 2003 SP1 machine in IIS 6. I can access the site by the domain from an external machine but I cannot authenticate with the site from within the same server by the domain. I can browse to the site RDP'd into it via it's domain name but no authentication to Active Directory is working. When I connect the same way (to the site on the hosting server) via the IP address I CAN authenticate with AD and everything works fine.
I can not authenticate to a domain name within the hosted server. I can authenticate with the IP address within the hosted server. An external machine can authenticate with the domain name and the IP address.
I have a DTSearch index spider running on the same machine as the website that needs to authenticate via Active Directory to crawl the website by domain. The problem is that the scheduler cannot crawl the website because it gets a 401.1 error.
I have seen this problem before and we fixed it but for the life of us we can't remember what we did. I know we found a Microsoft KB article on it but we could not find that again either.
Thanks for your help,
