I saw this issue randomly on Windows PCs due to IPV6 TCP checksum offloading. Try the following on the problem Windows machine: - Open the Device Manager -> Network Adapters -> Network Interface (Ethernet NIC):- Under the Network Adapter -> Advanced Tab, disable these options if present:TCP Checksum Offloading (IPV6) -> Disabled UDP Checksum Offloading (IPV6) -> Disabled - Try Windows update again
