Connecting outlook to a Exchange Server in a different domain

[Mc DLL]

Hello all,

I have the following scenario:

A network called A with Windows 2000 Server/Exchange Server 2003
working on a domain.

Another one called B with Windows 2000 Professional/Office 2000 only,
working on a workgroup.

They're connected through a leased line and it's possible to reach
each other already.

I tried to create Outlook profiles for the workstations on the network
B, but I simply can't go on, because they're not joinned to domain on
the network A.

Is there a way of using Outlook with Microsoft Exchange server, even
if they're not in the joinned to domain avoiding to receive the dialog
box "Enter password"?

Thanks
