When I try to access an Intranet site from a client I get asked to login all the time. Then I get a 401.3 error. The site works fine locally on the server.
The site has its own app pool, Managed Pipeline Mode is Integrated. I have set Read/Execute, List and Read permissions on the root web directory for the IIS_IUSRS group. Identity impersonate is false. Anonymous and Windows Authentication are enabled.
