In my expereince that value of 1 in Windows 2000 does not add much if any
protection from anonymous access. The options to restrict anonymous access
in Windows 2003 are more granular than in Windows 2000. The main three are
network access: do not allow anonymous enumeration of sam accounts, do not
allow anonymous enumeration of sam accounts and shares, and let everyone
permissions apply to anonymous users [which is disabled by default in
Windows 2003]. I am not sure exactly what you need configured and you could
test it out but I would advise that you read the KB link below that
discusses imcomapibilites of security settings with downlevel clients and
domains and goes into good detail on the anonymous access settings. In my
opinion the main concern is that your firewall protects your network so that
untrusted networks do not have access to information that they could
enumerate to use against you. Enforcement of strong passwords in the domain
will greatly reduce the risk of users being able to use the information that
they can access via a null session such as users/group names. --- Steve
