Sk1fj, посмотрите в свойствах сетевого подключения, нет ли сторонних клиентов/протоколов.
Примеры:

My Fix: Simply uninstall the Link-Layer Topology (Mapper I/O Driver and Responder) protocols, as well as the QoS Packet Scheduler service (you can add them back again afterwards) in the Local Area Connection of the client machine (not the server/target). You must uninstall, not simply remove the checkmark next to the protocol or service.

I uninstalled the Sonicwall Global VPN client and the problem went away.

Finally, removing Citrix DNE Lightweight Filter service from my network adapter solved the problem for me.
