I have an NTLM sharepoint site with host header on the Server. When I try to access this site from the server locally It asks me for the credentials 3 times and then finally giving me an unauthorized error. The site works fine from any non sharepoint farm machine with the same user credentials.

Now this may not be a big issue for me as I can browse the site from other machines. The real problem is regarding crawling as it is also getting access denied message in the crawl log and I think they both are related.

Server environment: WINDOWS server 2003 MOSS 2007 with service pack2

Does anyone know what I could do to fix this?

You might want to disable loopback checking.

For clarification, it's not recommended to disable the loopback check altogether, but instead add your site to the BackConnectionHostNames "white list", which is described in Method 1 in the above article. – Brian Meinertz Aug 9 '10 at 8:15
