Need a Proxy for Domain Users and DHCP Users (mixed environment)

[maurophp]

Hi there.
I'm looking for a solution that solve all my problems. I have a newtwork, Windows 2003 Domain.
We have 30 computers, connected to the domain. I can ghet those client to surf throught the proxy, using the GPO.
And using Windows Authentication they do not need to insert the password to surf the web.

Now.. I have some DHCP clients, althought… not connected to the domain.
I would like for those client that are not connected to the domain that the only way to surf the net is to pass throught the proxy, (the same one for the Domain clients) and I want them to be prompted with the login box (I don't care if it's a browser splash screen/capative portal or just a password box) where they have to use their domain password.
Can someone help me?

Thanks.
Mauro
