Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Now that we have applied an internal to external rule blocking all users access to the internet, other than those users in a whitelist, we have the obvious issue of non authenticated users, not on our domain, i.e.; domain-less guests not being able to access the internet. Other than configuring each machine to use our alternative gateway - which would require a member of IT to be onsite everytime a guest arrives - can this be done through ISA adn AD?

Tell us a little about these "guests". Are they on their own machines plugging into your LAN using DHCP? Are they using your machines, and if so how are they logging into yours? –  Bret Fisher Mar 1 '11 at 6:48
    
Are they on their own machines plugging into your LAN using DHCP - Yes or by wireless, but their own machines and own logins - no domain awareness. –  Klaptrap Mar 1 '11 at 8:37

You can create a rule to allow unhautenticated users Internet access and give it a higher priority than the rule allowing only authenticated users; but then, users would simply be allowed Internet access without authentication, because the second rule would never kick in.

You can create a guest account to be used by guest users, with very restricted domain access (or even only as a local non-admin user on the ISA Server computer) and only use it for Internet access.

This means that the guest machine will need to be domain aware which relies on a member of IT to be available and to configure each guest device? –  Klaptrap Mar 1 '11 at 6:19
    
No, the user will be asked for credentials when accessing the web and; there is no need for the machine to be joined to the domain for this to work. –  Massimo Mar 1 '11 at 10:04
    
Nice - I understand, okay & thanks. I'll trial this later –  Klaptrap Mar 1 '11 at 12:17
