Problem in network Windows 11 24h2

We have found the source for our problems, it seems with the update, it came with dependecies on some really oooooold service.

So here is what we did with the computers that the network doesnt work, I think there was also the solution with the regedit somewhere in this thread.

Procedure 1 (if device has no network at all - mostly PCs):

a. Obtaining LAPS or using a pcadmin account

b. Starting the CMD command line as pcadmin/Administrator

c. Entering the line: sc qc wcmsvc

d. Reviewing the lines entered

c. Enter a new line sc config wcmsvc depend= RpcSs/NSI

d. And check the success of the entry: sc qc wcmsvc

e. Reset the computer

OR

Procedure 2 (mostly for laptops if their LAN connection works):

a. Run Regedit as Administrator/pcadmin

b. Look for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinHttpAutoProxySvc

c. In the folder, find the DWORD "Start" the current value will be 4 (disable)

d. Enter a new value 3 (start)

e. Save

f. Reset the computer

This should fix the issues, it works at least in our company environment.

Hope it helps!

I appreciate the help. I would caution enabling WPAD from a security stand point. In-the-Wild WPAD Attack | How Threat Actors Abused Flawed Protocol For Years (sentinelone.com) We found in one of our cases that adding a static IP with a different DNS helped, but it is not a long-term solution with our infrastructure, and it is better for us to roll back when possible. I am hoping for a Microsoft fix :)

Thanks,

William

Bij mij ook alles weg ben twee uur bezig

Geweest met die zooi

I didn't have issues with internet access, but I did run into a problem accessing my network drive. Drive showed up, but was blocked by a security issue of some kind. Drivers were fully updated and verified the settings in the router. Verified the sharing settings. Rolled back to 23H2 and got access to the drive back.

For us it works to enable the random hardware IP address for the WiFi Controller (Intel Chipset)

best regards
