Can't find server when copying names.nsf to a new installation

When I install a new PC to a person and copy over the names.nsf to the new PC it can’t access the location and it’s still the same user accessing it. During the setup it won’t find my server because it can’t access the Office location document. Today I have to cancel the setup, rename names.nsf to names1.nsf and then go back into the setup. After that when it’s done I have to go into the addressbook and copy the old information to the new addressbook. How can I resolve this when I don’t have a working Notes to use to remove the Proxy requires authentication check?
