This is not a full solution, but your problem did seem familiar, as i had a laptop that was part of the network, with same WORKGROUP name, but i could not share files with it, only use net access. If i remember correctly i checked that all the protocols on each PC/Laptop on the network, were the same.
SO here is my suggestion:
Check the protocols of the laptop and desktop with the laptop having the problem.
Control Panel --->Network Connections ---> Right Click Connection ---> Properties
and you should see the list of protocols installed.
File and Printer Sharing
CLient For Microsoft Networks
are installed and "ticked" on each comp.
I hope you resolve this annoying issue.
