Hi, I have 4 PCs with Windows 11 Pro. Two of them have been updated with KB5050577, and since then they have encountered problems with the SNB connection. Specifically using wireshark I saw that the connection request is not addressed to port 445 but to port 80.Some tests:-----------------------40 5.820586 192.168.1.38 192.168.1.2 TCP 66 52731 → 80 [SYN] Seq=0 Win=65535 Len=0 MSS=1460 WS=256 SACK_PERM 41 5.823245 192.168.1.2 192.168.1.38 TCP 66 80 → 52731 [SYN, ACK] Seq=0 Ack=1 Win=65535 Len=0 MSS=1460 WS=256 SACK_PERM 42 5.823468 192.168.1.38 192.168.1.2 TCP 54 52731 → 80 [ACK] Seq=1 Ack=1
