Windows 10: Network Problems After Latest Windows Update

Has anyone had network problems following the latest update to Windows 11.Prior to the update I had a rock solid home network with 2 PCs.Immediately after the update I was back to an old problem of continually being asked for Windows Credentials to access PB-B and its shares from PC-A.PC-A can be accessed from PC-B with no problems.I use my Microsoft account to login to both PCs, so the username, password, and PIN, are the same on both.Any advice on what the update could have done, and a suggested fix, would be much appreciated.

How to Dump Networking Parameters?


Had a customer with this problem, they had a brand new Dell Optiplex 3050, with Windows 10 1709, and Realtek Gbit Family of lan adapters (wired connection). After much troubleshooting (many suggestions listed in the course of this thread), it turned out the PC needed a bios update. Among the updates listed on the dell website for bios version 1.52 (I flashed it with the latest 1.92) was "Update RealtekLOM".

LOM is "lan on motherboard" and the Realtek has flashable firmware.

One step for others having this issue is to check their computer manufacturer's website for "Lom" firmware updates for the particular network adapter - whether integrated or an add-in.
