Multiple domain support on exhange 2k

How can I install exchange server for a diffrent domain?

I have a windows 2000 domain which is “abc.com” but I want to install a exchange server for “xyz.com” in that domain, can I install like that? if yes then how?

Can I use virtual domains(or multiple domains) in the exchange 2000.

any help? if any reference given .. that will be great.

Thanks in advance.
