Lost Computers on LAN since Windows 10 update

[Fred Philpott]

Since my last Windows 10 update (1803) the Windows 10 and XP computers vanished from my network. Windows 7 and 8 were still visible.

After a lot of research I was able to make the Windows 10 computers visible again by turning on the Computer Browser service however one of them is not accessible from the others.

I have Office, Home, and Laptop. They have all been updated to 1803. Office and Home are Windows Pro. Laptop is Windows Home. They can now all see each other but Laptop and Office cannot connect to Home. The user name and passwords are rejected. Home can connect to the other two. BUT I can create a network drive "users (\\home\)(Z" from the other two.. My Android phone can still connect to Home as well using Total Commander LAN shares.

I can also create a network drive to the XP computer even thought it isn't visible on the network.

Before the updates everything was working fine. Anyone know what the heck happened and how I can fix it short of rewinding all three back with Recovery?

You can attempt to create a HomeGroup and connect to the PCs in that way.
Has worked for me in the past. Works on all Windows since Vista.

In the latest version of Windows 10, there are no more home groups. I also have this issue, on all but one of my 5 upgraded machines. Still looking for a solution. In the meantime I have created shortcuts to my network PC's instead, as well as modifying the default settings for networking and disabling IP v6. Windows 10 networking has been somewhat of a pain of late, and the demise of home groups has not really helped.

EDIT: Had a look around and a lot of people had this same issue. Just tried this and it worked for me, good luck... https://www.ghacks.net/2018/04/17/fix-pcs-no-longer-recognized-in-network-after-windows-10-version-1803-upgrade/

Thank you both for the info. The ghacks link was most informative. I'm looking forward to giving it all a try. Fortunately I never got sucked into using Home Groups.

With the latest Windows 10 update, they disabled SMB 1.0 which Windows XP uses, and therefore you can't communicate between the two. To get the function back, you need to go to control panel, uninstall a program, add features, then enable SMB 1.0. This will allow windows 10 and XP to be able to talk again!

Lemme know if it works

Though security concerns with systems are nowhere new, the mess caused by the Wannacrypt ransomware has prompted for immediate action among netizens. The Ransomware targets the vulnerabilities of the SMB service of the Windows operating system to propagate.

SMB or Server Message Block is a network file sharing protocol meant for sharing files, printers, etc, between computers. There are three versions – Server Message Block (SMB) version 1 (SMBv1), SMB version 2 (SMBv2), and SMB version 3 (SMBv3). Microsoft recommends that you disable SMB1 for security reason – and it is not more important to do so in view of the WannaCrypt or NotPetya ransomware epidemic.

SMBv2 wasn't disabled due to W7 devices.

I'd seriously consider changing that XP installation to a Linux one that still gets security updates, unless it has no network communication/storage drives connected, and even then I'd still consider it.
