The version of Windows is irrelevant in this case. What important is the
version of Outlook that is being used on both machines; are these both
Outlook 2000?
Do not use the import feature but use File-> Open-> Personal Data File...
instead.
If that isn't available either, or you get the same error, then add the
pst-file via Tools-> Accounts or Tools-> Services instead.
If that still doesn't work, rerun the Office 2000 installer and make sure
you have support for pst-files installed.
The difference in naming (Services or Accounts) is caused by the
installation mode that you used; IMO or CW Mode. In order to get Outlook
2000 working on Windows Vista, you need to install it in CW mode (which you
did). Note that you'd still be in an unsupported configuration though and
other issues might arise.
