ok so here is the bizarre issue now.
the desktop sees the homegroup it started as something it needs to join, even though it is the one that created it.
what the heck.

all services including the homegroup ones are started on both computers.

desktop cannot see the laptop thru network but can if I share to the homegroup. it has all the services activated.
