Can not connect to network shares

I have a wdlive unit with fw  version 1.06.15_v and I can not get it to connect to my network shares on my xp machine. Currently have tried rebooting the wd device and computer changing share options, changing workgroups, and checking for new updates also have cleared network names and passwords, adding passwords to the computer and taking them off. Not really sure what happened just one day it had stopped. Any ideas?
