is it still working on his old laptop?
not sure if I can help as it’s been a long time but since no one has answered yet, I’ll try to give you some ideas that could cause it
it might have to do whith the user no longer existing on the server?
try cheking the address book (on the server not local) see if he still exists.
if he is still there check the properties he maybe located on a different server ie xxxx01 instead of xxxx02
another possibility is his idfile was recreated/renamed you might need to get a new copy from the server.
you can also try useing a fresh new copy of the notes.ini file as your information and his may not necessarily be the same
hope this helps
