5. Result: "The Windows Defender Firewall rule SMB Block Outbound is blocking your connection"
Is that controlled by Group Policy? I've read some post saying a user was able to convince his Admin to adjust GP so he can use ReadyShare again...
That is interesting, and probably the problem for you. I don't use Windows Defender for the Fireware, I have Norton ISS installed with does it.
Wonder if you ran some 'WannaCry" program that 'protected you against it and it made changes for you?
What you will need to do is open Settings for Windows Defender and see what rule is blocking port 445, and there could be others as well.
Some reading:

A lot of those are duplicate info mostly, but worth looking at them.
Better yet, before venturing down that path, why not just TEST with the Defender Firewall turned off and see if that is actually the problem?
You are running the Fall Creator version of W10. Windows will shutoff SMB1 if you are not using it.
Check if SMB1 is running, open a CMD prompt and enter sc query mrxsmb10
Should look like this:
=========
C:\>sc query mrxsmb10
SERVICE_NAME: mrxsmb10
TYPE : 2 FILE_SYSTEM_DRIVER
STATE : 4 RUNNING
(STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x0
======
If the STATE is NOT running, that is the problem.
Entering NEW VIEW in the CMD prompt should also produce an error. Note that the problem could be caused by other Windows 10 PC having the problem. One PC without SMB1 running will 'kill' sharing by name.
In order to enable SMB1 one there are a few ways... easiest is to go to the Control Panel, Programs and Features, Turn on Windows Features, scroll down to SMB 1 and just click on the CLIENT. You will need to reboot for that to be started, should cure the problem (unless other PC need this done too).
Hi IrvSp,
Thank you for offering help.
SMB1: MS strongly recommend that you do not reinstall SMBv1. This is because this older protocol has known security issues regarding ransomware and other malware.
However, I run sc.exe query lanmanworkstation and see SMB2 is enabled. Could you suggest further resolution?
SERVICE_NAME: lanmanworkstation
TYPE : 30 WIN32
STATE : 4 RUNNING
(STOPPABLE, PAUSABLE, IGNORES_SHUTDOWN)
WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0)
CHECKPOINT : 0x0
WAIT_HINT : 0x0
Thanks in advance,
