Fax and Scan Question (using computer in domain)

A client of mine has Vista Ultimate. Uses fax and scan heavy in his
workplace. Recently, his network moved from Domain A to Domain B. This
resulted in his computer creating a new user account when the user logged in
under the new domain (while the old domain was history).

Under the user's account in Domain A - he used fax and scan a lot and stored
everything appropriately. While he is enjoying using his computer under
Domain B and his new account - he's unable to import old faxes and scans.
He's located the fax and scan files that he used under his old account, but
while using his new account, he can't retrieve those. This sounds like some
crazy active directory question, but it's more fax and scan. Basically, he
doesn't care who's account is logged into the computer - we are trying to
figure out how to take previous faxes and scans and import (or move some
files, change a registry entry..anything) so when he uses the computer (under
his normal everyday account) - he can still see and use all his faxes and
scans.

How can this be done? Documentation on the fax and scan in Vista is
horrible and I haven't found anything technical about it anywhere. Thank you.
