Today ( 3/2/16 ) I got 2- W10 updates, KB3140743, and KB 3139907 which brought it up to build 10586.122 and the W10 computer now sees the other network computers in
file explorer>network.
Thanks R. Proffitt for at least trying to help when no one else did on here.
Network computers could be seen in file explorer>network on my win 10 laptop with ver. 10240, but after ver. 1511 network computers cannot be seen in file explorer>network.
NOTE: I can type the PC name as a share into the file explorer address bar and it will appear but closing file explorer means a repeat of the process of typing it in.
Here is my network setup so maybe it will shed some light:
There are 4 computers on my workgroup network, 3 of which have assigned IP's and the Win 10 is Obtain IP auto, all but one ( which as a shared folder ) having my named administrator account and the same password on all.
Computer 1= workstation 2, Win 7 Pro 64 bit ( which doesn't show up on the Win 10 in network list ).
Computer 2= workstation, an older Win 7 Pro 32 bit which I seldom have on. I just happened to have it on yesterday and it showed up on the Win 10 in file explorer>network listing.
Computer 3= XXXX-PC which is my girlfriends computer, Win 7 Pro 64 bit with a "Shared folder" that I can access because I have an account setup on it. But it no longer shows up on the Win 10 computer in the network listing.
Computer 4= workstation 5, HP ProBook 450 G2 i7, Started as Win 7 Pro 64 bit upgraded to Win 10 ver. 10240 which showed all of networked computers, upgraded to ver. 1511 which now only shows itself and the 32 bit Win 7 computer in file explorer>network.
Conclusion so far, for some unknown reason the 32 bit old computer shows up but the newer 64 bit computers do not show up. Evidently when opening file explorer, it search's for other computers on the network but it is only finding the 32 bit. I'm assuming that there is a setting somewhere that must change when ver. 1511 is applied.
Any help to shed light on the problem would be appreciated, thanks.
