Why is my network messed up after update to windows 11 24H2

This batch of updates totally ruined my day today, taking down the network share to our main machine, unable to recover this to make it work again, I spent 8hrs today trying to resolve this and got nowhere. The resolution for me is now to have to build a new drive to hopefully work again, I hate Microsoft as a platform, they just make any IT work a trauma to deal with. Now I am faced with installing the OS onto a new drive, to then have to copy data bit by bit over to the new drive, each time testing that something else doesn't break.... Apple all the way for me, when I am able to step away from supporting Microsoft products, the better. Microsoft has ALWAYS been garbage software.

Hi Elipel,

I'm Sumit, here to answer your query at the Microsoft Community.

Apologies for any inconvenience you are experiencing. We are happy to help you.

I think some services might have been turned off. Could you ensure these services are running?

Make sharing services start automatically.

Press the Windows logo key + R.

In the Run dialog box, type services.msc, and then select OK.

Right-click each of the following services, select Properties, if they're not running, select Start, and next to Startup type, select Automatic:

Function Discovery Provider Host

Function Discovery Resource Publication

SSDP Discovery

UPnP Device Host

Hope that helps, and rely on us for any further inquiries. All the best.

I have 2 Conceptronic CH3HNAS NAS drives connected to my Windows 11 home network. After the latest 24H2 update, the NAS drives are no longer visible via Windows Explorer. I have tried everything proposed in this thread, plus other things I've seen on the Internet, without success. Hopefully Microsoft can identify the cause of this widespread problem and issue a patch as soon as possible. Meanwhile, I've rolled back my computer to a latest full system image of Windows 11 23H2 and temporarily disabled Windows auto update.

Hello,

the services Function Discovery Provider Host, Function Discovery Resource Publication
SSDP Discovery and UPnP Device Host were ok and running (Automatic)

(network discovery turned on)

(On my laptop windows 11 23 H2 i see all devices in my network)

So no solution yet

Got the same problem.

My Synology NAS and other PC's with shares do not show up in "Network". Thou typing it's explicit name or IP-adres, gives me access.
It does show as a "Media device", but not for file sharing.
Same for my "old" pc, sharing a couple of directories on Windows 10 pro

They do show up in "other devices", but that opens their webpage or give information, not the shares.

All the mentioned services are up and running. And everything worked fine in 23h2

OS: Windows 11 Pro 24h2
NAS running SMB sharing
Win 10 Pro PC's, windows file sharing

Problem solved:
Had to enable "server signing" on my Synology NAS. It was already user + password protected, but this option put my NAS back on the "Network".

Also had to tick "allow other network users to connect through this computer's internet connection"

Windows 10 Pro pc's are back on "Network", so is my NAS.
