WinXP and 98se networking

on my WinXP Pro machine, I have created the same users as on my 98se machine, as well as gave them permissions on all shares …even for testing purposes, put them all under the administrator group. But I always get an ‘error 31’ message, when I try to connect from the Win98se machine.

But when logging on as the local administrator account on the 98se machine, I connect properly …PLEASE HELP!!
