401.1 means that the username/password that you gave to IIS for
authentication was incorrect. If this happens when you have Anonymous access
enabled, it means that the username/password you configured in IIS for the
anonymous user is NOT the same as the NT user in the local SAM. Please
synchronize them and try again.
The reason you can get a 401.1 for anonymous access is this -- when you
select anonymous, what IIS does is authenticate as a configured user
identity for every single request and use that identity to access resources.
This allows you, for example, to ACL files to allow/deny the "anonymous"
user access even though you enabled anonymous access. However, if this
configured user identity has credentials that do not match reality, IIS
fails to authenticate as this user and as a result anonymous access fails.
In general, the other authentication methods are pretty fast, unless your
website/application intentionally causes re-authentication, at which point
you lose 2x-3x your website's bandwidth wasted on re-authentication. But,
that's a problem caused by your application.
Can you give:
1. Authentication types enabled.
2. IIS version
3. If IIS6, whether you are running in IIS6 native mode or IIS5
compatibility mode
4. If IIS6 in native mode, what is your Application Pool Identity

Internet Information Services (IIS)" i set this initially to allow annonmouse access, i checked all the permissions and they seem to be right, i tried using basic windows authentication, which did work but was very very slow can any one help me resolve this issue as i have tried everything i could think of but this didnt seem to fix the problem. i dont understand if i have the site and all relevent perm's set to allow annonmouse access why its telling me that a credentials issue is happening, i googled this error and found a microsoft hotfix however upon reading about the (/) being used to seperate domain name and user name the iis user account had already been set up to allow that so it wasnt that. can any one help me? many thanks ben
