Please help me resolve this home network issue

To reference other PCs by NetBIOS name in order to make an IP connection requires that you have NetBIOS-over-TCP/IP enabled on all PCs, and that you have configured Windows Firewall to allow Microsoft File and Printer Sharing as an Exception. You should also ensure that all PCs have the same Workgroup name configured.

You can input your computer name and IP address into LMHOSTS file located at C:\Windows\System32\Etc folder.



Please download MiniToolBox, save it to your desktop and run it.

Checkmark the following checkboxes:

• Flush DNS
  Report IE Proxy Settings
  Reset IE Proxy Settings
  Report FF Proxy Settings
  Reset FF Proxy Settings
  List content of Hosts
  List IP configuration
  List last 10 Event Viewer log
  List Installed Programs
  List Users, Partitions and Memory size.
  List Minidump Files

Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.

Note: When using "Reset FF Proxy Settings" option Firefox should be closed.



Can you also reset Windows services to there default startup type using my batch script attached to this post.

I enormously appreciate you guys trying to help me. I've tried everything listed here with no success. I'll attach the log here.

To be sure there’s no hardware or router problems, and just for testing, I backed up the system, and then installed a FRESH copy of Windows10. My other network PCs connected to the PC without any issues. I’ve now restored back again.

I have TeamViewer installed if anyone thinks they can fix this for me

start with the Basics.....Does EVERY PC have a Password? this is a MUST with Win10. Networking on Win10 WILL NOT work if there is no Password present for Logon... or it's Blank (M$ considers this a security risk)

you can however use the Tutorial here on TenForums to bypass the Logon when you start your computer.... and even the Lock Screen

Are all computers connect to same Default Gateway . . . . . . . . . : 192.168.1.254?

Maybe changing PC1 computer name will help resolve the issue.

I would like you to check the system integrity of your Windows OS installation.

• Please type cmd.exe into Start Menu search box.
• Please right click cmd.exe and select "Run as administrator".
• Please type the following command and press the <Enter> key: sfc /scannow (Please note that there is a space between 'sfc" and "/scannow".)
• It should take about 20 minutes to run, if there are no serious errors.
• If the System File Checker reports that some errors were fixed, but some remain; please reboot your computer and run the System File Checker from an Administrator Command Prompt, again.
• If the System File Checker again reports that some errors were fixed, but some remain, please reboot your computer and run it a third time.
• If "Resource Integrity Violations" (errors) are reported that could not be corrected, or were not corrected after a third SFC run, then please navigate to the folder: C:\Windows\Logs\CBS and copy the file "cbs.log" to your desktop immediately. I am asking you do that because that file is dynamic, so I want to be able to examine a copy that is unchanged from the time that the System File Checker was run.
• If there are errors that couldn't be corrected, let me know and I will provide you with instructions as to how to upload the file.

Also execute Dism /Online /Cleanup-Image /RestoreHealth command.


You can also try repair install Windows 10 without losing anything.

This is news to me. I do not use Windows passwords at all (never have).
I've been running this EXACT same network configuration since Win10 was launched, without these passwords and never had an issue.

FIXED!!

How on earth could it be something so simple as a PC name!!??
Windows updates must have made a change, as the machines have been named this way for years;-)

All the other machines have the same naming convention and run just fine.

I'm massively grateful for the amazing feedback and help I've here. Especially for you sir. I'm guessing you are or were a network engineer?

You are very welcome!

I'm not a network engineer but i do have basic networking knowledge and use my Windows OS knowledge to troubleshot errors.
