logon to mulitple domains

I have a teacher who is now teaching at 2 schools. he wants to be able to log onto the domain at each school. One had a windows 2003 server while the other is windows 2000 server. I've done some searching but doesn't look promising. Has anyone been able to do this?

thanks Brent

Not at the same time I hope?

sorry it took so long to get back.. No different times. but wants different domains in the domain drop down so he can choose.

Do you have admin priviliges to any of the domain servers?

If you do you can establish a trust relationship with the other domain server. This would put both domains in the dropdown box.

I was thinking about this and the user should just be able to enter their email address in the logon user box.

if domain was location1.com, then user would logon with [email protected]. If domain was location2.com then user would logon with [email protected].

Dropdown box is not available when using entire email address.

thanks troyz, will give this a shot. i have admin on both but they are in different locations not connected by lan or wan although they may be in the future.
