Installing an NT 4.0 Server in a foreign

I am setting up a Proxy server that will be used by a business unit that is in a separate domain. Our domains do not have a trust relationship established.

When I am installing NT Server, is there a way to install the server on the foriegn domain?

In other words, I am in “Domain X” and I want to create/install an NT Server (standalone) that will be a member of “Domain Y”. How is this done without trust relationships?
