Multiple domain choices when logging on From WinXP

I have a PC in a domain, but I want to allow it to attach to another totally
unrelated domain in another company without having to unjoin and rejoin
domains. I can get and domain admin in both companies to make my computer a
member of their respective domain, but I don't want to have them do this
every time I want to log on to a different domain. Others I know say they
have seen Windows XP logon screens that allow multiple choices of various
domains, but everything I have read says you can only have one domain choice.

Jonah,

Being a member of a domain involves a two way trust relationship - your computer
trusts the domain, and the domain trusts your computer. Generally, your
computer will only trust one domain, at any time. There are software products
which work around this limitation.

The only way you can have multiple domains to choose from at login is if the
domains have external trusts between them. Otherwise, one computer, one
domain.
