Lost network with W11 24H2 install

mikejp · Jun 24, 2025

Perhaps unwisely(!) I have just upgraded a W10 laptop to W11.. While the W10 machine can see my other W10 laptop there is no sign of the W11 machine and "network path cannot be found".

Tried all know fixes including several network resets. Even the wifi on the W11 machine seems unreliable.

mikejp · Jun 24, 2025

System details added. I have seen elsewhere that 24H2 can cause issues with networking. Sadly none of the tutorials (if that is what you mean by 'search'?) actually helped.

What is stumping me is that the laptop was fully visible and accessible when running W10 but my W10 desktop cannot resolve the W11 laptop at all. On the occasions that I have had a 'glimpse' of it in the network (generally after a network reset) the network path has been unobtainable. I have even tried the 'fix' on here in GpPol to no avail.

Hoping someone here understands the vagaries of networking in Windows.

Do this on all systems in network..

add "LanmanWorkstation" as an additional startup dependency for the "Function Discovery Resource Publication" (FDResPub) service, which seems to do the trick. To do this, you simply open an elevated command prompt (i.e. use the "run as administrator" right-click context menu option to start cmd.exe), then execute the following command:
sc config fdrespub depend= RpcSs/http/fdphost/LanmanWorkstation
Restart

Make sure these services are set to automatic and running

DNS-Client – Server
Function Discovery Provider Host
Function Discovery Resource Publication
SSDP Discovery
UPNP Device Host
Windows Defender Firewall

All done, thanks, glas, and 'success' with the script, but so far sadly no improvement.

Press the Windows and "R" keys simultaneously, type or paste
"msdt /id NetworkDiagnosticsInbound" into the "Open" box and click "OK".

Microsoft has never mastered file sharing. When it works, it works, but when it doesn't what works for one does not work for the next guy.
Try this one then. It's copied from @Brink's tutorial. Share Files and Folders Over a Network in Windows 10

Enable SMB Direct on each computer you want to share between. If you have an older USB network drive or connecting to a previous version of Windows (ex: "Windows 7") than Windows 10, then you will need to enable SMB1. (see screenshot below)
SMB Direct will not be available in the Windows 10 Home edition. You will need to enable SMB1 instead.

If you enable SMB1, be sure to uncheck Automatic Removal.
It is recommended you do not enable SMB1 unless absolutely necessary for security reasons.

If you enable SMB1, it will also enable and have the Computer Browser service to run which could potentially cause 10 minutes + delay in discovering a PC newly connected to the network.

Still no joy, as a workaround, see if you can access the 11 computer using computer name. If you can, you can create a shortcut and pin it to quick access.

Open File Explorer.
In the address bar, type the following: \\computername (replace "computername" with the name of the computer you're connecting to).
Press Enter.
Note: You can also use ip address in address bar
Whichever of these methods allows you to get to the other machine, create a shortcut to it on desktop, and pin that shortcut to quick access. You can then delete the shortcut from desktop.

SMB Direct requires a server on the other end (or the Pro edition for Workstations). It also requires a network adapter with RDMA.

It does nothing for you on a home network, unless you have a Windows Server OS or Pro for Workstations.

The OP may also try to enable "Allow Insecure Guest Authentication" in his PCs and see if he has connection to other PCs in his home network.

This web site also advises to make changes to Insecure Guest Authentication for Windows 11 and Windows 10 PCs not seeing each other on the network.

In desperation I successfully connected with the Win11 machine via Anydesk which I know is not much help, but at least it proves the damned thing is working on the internet and at least I can access its files! Still no joy via Networking - just cannot reach the machine.

I can ping the IP (192.168.1.117) but not the given network name 'MIKELAP' (not found)

Re Post5, Ben, that produced a 'troubleshooter' I have not seen before dealing with inbound connections - promising! Ran it, told it I cannot find the machine on the network and it could not identify the problem!! However, a sniff of success there?

mikejp · Jun 25, 2025

Correction:
"but not the given network name 'MIKELAP' (not found)"

I was trying to ping \\MIKELAP. Ping MIKELAP worked. Where is the thing hiding?

ipconfig shows an IP of .117 whereas in my router I have a fixed ip for the laptop of .201. Can this be causing the issue?

suatcini54 · Jun 25, 2025

Have you made MAC-IP reservations in your router for your networking devices and yet you have given static but different IP for your problematic PC ?

Do I understand correctly that this is the situation ?

Please also read this for changes in networking for Windows 11 24H2: Enable insecure guest logons in SMB2 and SMB3 for Windows client and Windows Server

Wolfzz · Jun 25, 2025

What I do with every 24H2 Install or Upgrade

In Control Panel\All Control Panel Items\Programs and Features\Turn Windows Features on or off.
Check if there are No Ticks are on SMB 1.0/CIFS Client and SMB 1.0/CIFS Server Only a tick on SMB Direct

Make Sure you are on a Private Network NOT Public

Next go into Group Policy (Pro Version Only) gpedit.msc

Computer Configuration, Windows Settings, Security Settings, Local Policies, Security Options
Double click on Microsoft Network Client: Digitally sign communications (always)
Double click on Microsoft Network Client: Digitally sign communications (if server agrees)
Set both of these to "Disabled"
Click on OK.

Computer Configuration, Administrative Templates, Network, Lanman Workstation
Double click on "Enable Insecure Guest Logons"
Set this to "Enabled"
Click on OK.

Reboot

Works everytime

Before I go any further I have discovered that each restart and or network reset turns off Network Discovery which I assume is the problem (private network). Is there a reg or gppol setting that controls the default?

Just set the service to Automatic/Delayed Start.

mikejp · Jun 25, 2025

That is set but service is not running and will not allow me to 'start' it.
'Error 1075
; The dependency service does not exist or has been marked for delete'

Function Discovery Resource Publication depends upon HTTP Service, Remote Procedure Call (RPC), and Function Discovery Provider Host. The host service also depends on HTTP and RPC.

mikejp · Jun 25, 2025

I think Ihave checked all the dependencies, but services.msc does not hold HTTP Service?

pseymour · Jun 25, 2025

It doesn't show there, I believe. You can check it with PowerShell.

Code:

ps> Get-Service 'HTTP'

Status   Name               DisplayName
------   ----               -----------
Running  HTTP               HTTP Service

Thanks - running.
