Disable Loopback Check

There is a security check in Windows 2008 which was introduced since the 2003 server version. This check ensures that a web application cannot be accessed using a fully qualified domain name on the host machine.  If you try to do so, the system returns an access denied error (401.1 error).  In actual fact, the login even though is correct will get challenged and produce a logon failure if you check the event log. The way to fix it is to make changes to the registry by following the steps below: Login to the Windows File Server Open regedit Allow other machines to access share using aliases Change Disable Strict Name Checking in the registry Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters Add a DWORD named DisableStrictNameChecking Set value to 1 Also Proceed to HKLM:\System\CurrentControlSet\Control\Lsa\MSV1_0 -Name “BackConnectionHostNames” and add the FQDN of the web application to it.
