The Remote Desktop Protocol (RDP) connection to your Windows-based Azure virtual machine (VM) can fail for various reasons, leaving you unable to access your VM. The issue can be with the Remote Desktop service on the VM, the network connection, or the Remote Desktop client on your host computer. This article guides you through some of the most common methods to resolve RDP connection issues.
Jan 13, 2014 The Microsoft Network Adapter Multiplexor protocol is checked in the teamed network adapter and unchecked in the physical network adapters that are part of the NIC Teaming. For example, if there are two physical network adapters in a team, the Microsoft Network Adapter Multiplexor protocol will be disabled for these two physical network. Mar 05, 2020 Should I Enable the Microsoft Network Adapter Multiplexor Protocol? As I mentioned before, the Protocol only works when teaming or combining multiple Network Adapters. If you try to enable this option by selecting the option manually while the other items in the list are enabled, you will see this error.

In this topic, we provide you with instructions to deploy Converged NIC in a Teamed NIC configuration with Switch Embedded Teaming (SET).
The example configuration in this topic describes two Hyper-V hosts, Hyper-V Host 1 and Hyper-V Host 2. Both hosts have two network adapters. On each host, one adapter is connected to the 192.168.1.x/24 subnet, and one adapter is connected to the 192.168.2.x/24 subnet.Step 1. Test the connectivity between source and destination
Ensure that the physical NIC can connect to the destination host. This test demonstrates connectivity by using Layer 3 (L3) - or the IP layer - as well as the Layer 2 (L2) virtual local area networks (VLAN).

Many network configurations make use of VLANs, and if you are planning to use VLANs in your network, you must repeat the previous test with VLANs configured.
For this step, the NICs are in ACCESS mode. However, when you create a Hyper-V Virtual Switch (vSwitch) later in this guide, the VLAN properties are applied at the vSwitch port level.
Because a switch can host multiple VLANs, it is necessary for the Top of Rack (ToR) physical switch to have the port that the host is connected to configured in Trunk mode.
Note
Consult your ToR switch documentation for instructions on how to configure Trunk mode on the switch.
The following image shows two Hyper-V hosts with two network adapters each that have VLAN 101 and VLAN 102 configured in network adapter properties.
Tip
According to the Institute of Electrical and Electronics Engineers (IEEE) networking standards, the Quality of Service (QoS) properties in the physical NIC act on the 802.1p header that is embedded within the 802.1Q (VLAN) header when you configure the VLAN ID.

Important
It's not uncommon for a Test-NetConnection or ping failure to occur immediately after you perform Restart-NetAdapter. So wait for the network adapter to fully initialize, and then try again.
If the VLAN 101 connections work, but the VLAN 102 connections don't, the problem might be that the switch needs to be configured to allow port traffic on the desired VLAN. You can check for this by temporarily setting the failing adapters to VLAN 101, and repeating the connectivity test.
The following image shows your Hyper-V hosts after successfully configuring VLANs.Step 4. Configure Quality of Service (QoS)
Note
You must perform all of the following DCB and QoS configuration steps on all hosts that are intended to communicate with each other.

Assign an IP address to the SMB Host vNICs vEthernet (SMB1) and vEthernet (SMB2)
The TEST-40G-1 and TEST-40G-2 physical adapters still have an ACCESS VLAN of 101 and 102 configured. Because of this, the adapters tag the traffic - and ping succeeds. Previously, you configured both pNIC VLAN IDs to zero, then set the VMSTEST vSwitch to VLAN 101. After that, you were still able to ping the remote VLAN 101 adapter by using the MGT vNIC, but there are currently no VLAN 102 members.
*
Remove the ACCESS VLAN setting from the physical NIC to prevent it from both auto-tagging the egress traffic with the incorrect VLAN ID and to prevent it from filtering ingress traffic that doesn't match the ACCESS VLAN ID.

Results:
*
Inspect the mapping of SMB1 and SMB2 to the underlying physical NICs under the vSwitch SET Team.
The association of Host vNIC to Physical NICs is random and subject to rebalancing during creation and destruction. In this circumstance, you can use an indirect mechanism to check the current association. The MAC addresses of SMB1 and SMB2 are associated with the NIC Team member TEST-40G-2. This is not ideal because Test-40G-1 does not have an associated SMB Host vNIC, and will not allow for utilization of RDMA traffic over the link until an SMB Host vNIC is mapped to it.

You want to validate the RDMA functionality from the remote system to the local system, which has a vSwitch, to both members of the vSwitch SET team.
Because both Host vNICs (SMB1 and SMB2) are assigned to VLAN 102, you can select the VLAN 102 adapter on the remote system.
In this example, the NIC Test-40G-2 does RDMA to SMB1 (192.168.2.111) and SMB2 (192.168.2.222).
