Hi,

The error "Not implemented 501" means the server does not support the functionality required to fulfill the request. This is the appropriate response when the server does not recognize the request method and is not capable of supporting it for any resource.

Hi,

To solve your problem, Type about:config into the URL bar, you will see a list of configuration settings for Firefox, then locate the setting for 'network.automatic-ntlm-auth.trusted-uris' and then Set the value of the above entry to the names of the servers you wish to use NTLM with.
