Multiple Domains

I have an interesting issue. I have a consultant that will need access to my domain on a regular basis so I'll create him an account and join him to my domain. However, I don't want to inconvenience his IT department when he returns back to his home office by having to go through it all again to rejoin his domain.

I don't want to have to join him to my domain using admin credentials every time he is here.

Ideally I'm looking at Windows being able to give a choice between two domains.

Any thoughts?

It would help me to give you more detailed recommendations if I knew what kind of access would be required. And I'm guessing we are talking about a Windows server based domain, correct? In conjunction with Active Directory?

If that is the case all he would need is a user account with the rights you deem fit and you'd need to setup permissions on folder/file resources he needs access to.

Usually, trusted or not, as long as a computer is part of the same subnet, and with valid credentials available, resource access should not be a problem.
You cannot join a computer to two domains. That is not possible.

It depends on the access that he needs. To use an Exchange email account does not require the computer to be joined to the domain, as long as the computer is on the same subnet. I have my work email on my personal laptop as well via Outlook, so it's easier for me when I'm on call.

If he requires folder access, he can simply access folders by providing the domain credentials you gave him, e.g. for the username: domain\user and the password.

Otherwise you could provide him with a remote login to a local workstation that is part of your company domain, or, if you have a terminal server, that would do as well.

I was afraid of that. So in essence, if I want to join him to my domain I'll need to do so with admin credentials every time he is here.

Are these trusted domains?  If so then you could grant him access to resources on your domain while his computer is joined to another domain.

No, unfortunately they are not trusted domains nor will they ever be.

Yes it is a Windows based network. Ideally I'd like him to be able to authenticate using IAS to my wireless (Aruba) and perhaps browse and open folders on the local network. I really didn't look at it from your perspective. I see how that will accomplish what I need. I will give it a try.
