Homegroup broken again in B10130?

after earlier builds broke homegroup, working fine me in
10074, since updating 10130 it's once again misbehaving (though
differently earlier).

although can join/leave/re-join homegroup, , apparently list
users , computers/shares in homegroup without a
problem, attempt see contents of shared folder on a
homegroup computer fails with:

[window title]

i've resorted uninstalling network adapter (realtek pcie gbe
family controller) device manager , scanning hardware
changes re-added.

after minute or 2 (and surprisingly, i've not needed re-add the
machine homegroup, settings remembered), homegroup
shares working again.
