PCs no longer visible on Network after auto Windows Updates 10 Pro

I have 8 computers on a Network running MS Windows 10 Pro and all of them access a shared folder on a server computer. Now, 2 of the computers are no longer visible on the network after MS updated the computers during the night. The Windows Updates were:
Update for Windows 10 V1607 KB3211320
Update for Adobe Flash Windows V10 1607
Feature Update for Windows 10 v1607

For example, using Windows File Explorer, I would click on "Network" and it would list all of the computers on our network. At that point I would click on the "Server" computer and a list of the folders that I have access to would be displayed. Now, the Server computer is no longer visible on the network using Windows File Explorer. I am confident that the culprit is Windows automatic update because this happened once before on another machine and the problem was resolved after I removed the MS updates.

Does can anyone suggest a solution to my problem which doesn't involve removing the updates? I am reluctant to remove the updates again because I know it is important to remain current and I am worried a subsequent update will cause a repeat of the problem. Any advice is greatly appreciated!

That last one in your list is the Anniversary Update. This is not a simple cumulative update, it a complete install of the latest version of Windows 10. For 10 days after the install you have the option to roll back to your previous version.

How is your network set up? Do you use a Homegroup or a Workgroup?
