Cannot see Computers any longer in network window after upgrading to Windows11 24H2, HELP!

I found this script (save as a batch file) somewhere. It worked for one clients home network after the update to 24H2. I haven't used it since and I claim NO responsiblity, ownership, or authorship of it's contents:

Did you do Windows Updates on Windows 11 24H2?? I had no trouble connecting any network or anything.. SO.. best of luck.

btw, network computers browsers isn't reliable.
access remote computer directly with "Run" dialog (keyboard Windows + R) then :
\\remote-computer\shared-folder

 

go into your network setting and make sure your network discovery is turn on....also go into windows tools click on services scroll down to ....

Function Discovery Provider Host and click it to automatic
Function Discovery Resource Publication and click to automatic
SSDP Discovery and click it to automatic
UPnP Device Host and click it to automatic


see if that works for you.....also reset your router and refresh the routing table....see if that helps.

 

I have does same network issues for a while , what i have found out if i leave my computers on after 3-4 days the network refreshes and i can see my share computers again....i agree 24H2 does have issues with network sharing.

 

I had never had issues Network sharing on base Windows Server 2022, TrueNAS, Any hardware NAS box.. Never had trouble.. Soundly your driver my have issues??

No this is not a driver issue.

 

I was forced to upgrade to 24H2 two days ago. I lost all my network. 4 Computers, 2 Nas, 2 Printers, DLNA server all disappear. Also the computer itself did not show in Networks. After hours of 'fixing' settings, I did a roll-back to 23H2 and added a block on 24H2 with Gibson's InControl reg patcher.
I had planned to do Rufus unsupported hardware upgrades to 24H2 on two of the computers. But, after dealing with this, I did 23H2 instead and added the 24H2 blocker. I can wait

 

it is not a connecting problem, it is network/sharing problem. All the devices in your Network folder disappear. Some of us actually have home networks.

 

That pretty odd because I tested Windows 11 (Pro 24H2 and all way up editions to IoT 24H2) and I see all my network no problems with Windows Server 2022 and rest my NAS on base 4 - TrueNAS 24.xx and 3 - ASUSTOR NAS and rest of PC ! Seem strange some of you had issues...

If you install SMB1 in win 11 you may need to run a cmd window and paste the following:

sc.exe config lanmanworkstation depend= bowser/mrxsmb10/mrxsmb20/nsi
sc.exe config mrxsmb10 start= auto

Also check Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

Should have a dword: SMB1 with a value of 1 (0 is disabled, 1 is enabled)

 

SMB1 has many security vulnerabilities, including information disclosure and remote code execution. Hence it's disabled and no longer used in modern Windows.
You would only enable it if you were sharing files to an old device, like an old android media player with SMB1 support...

 

MS has added to the feature SMB1 and automatic removal as SMB can pose a security threat, in Windows features check if "automatic Removal" is checked, uncheck it. Open regedit, navigate to the parameters key in LanmanServer, right click in a blank area on right side, select "new" slide out select "DWORD(32bit)", (don't use 64 bit regardless of windows architecture). The value is created waiting for you to rename it "SMB1", Press enter to commit the new value, then hit enter again to open and verify the value is set to "0", close by selecting ok. Close regedit and reboot. When Windows comes up go into the network, devices and pc's should start to populate. Check your firewall too. Could be blocking file and print services ports. After all that, if still cant see PC's try running sc commands from above.

 

You are correct the SMB1 value should be 1 for enable.
