Ok try this, on the laptop, change the name of the Workgroup to something else temporarily, like Workgroup1, hit apply, also add a description for the machine at step #7 just type Workgroup for description.
Restart the machine then change the name back to Workgroup and just leave the description as Workgroup. See if anything changes. You may need to do this on both machines.
