Hi
Those settings do not affect HTTP based authentication (for example, LANMAN
is never used when authenticating between browser and IIS). They are for
things like SMB, NetBIOS etc.
You say you are getting a 500 error (Internal Server Error). In your copy of
Internet Explorer, please goto Tools -> Internet Options -> Advanced, and
uncheck "Show Friendly HTTP Errors", and reload the page. Post the full
error message you see now.
Cheer
