NIC Teaming is disabled by default. If you want to enable it, you need to have at least two physical or virtual network cards. If you decide to enable NIC Teaming in guest operating systems using virtual network cards, some options will not be available.
In this article, I will show you which options are available and how to configure NIC Teaming in Windows Server 2022 using Server Manager.
In my scenario, I use a machine running Windows Server 2022 with three NICs (network interface cards) and combine them into a single NIC Team.
How to set up NIC Teaming
All your network cards need to be connected to the network and have a valid IP address.
- Open Server Manager.
- Select Local Server.
- Under NIC Teaming, click Disabled.
- Click Tasks and then New Team.
- Define the name of the NIC Team and select the relevant network adapters.
Under Additional properties, you can configure Teaming mode, Load balancing mode, and Standby adapter.
There are three teaming modes available: Switch Independent, Static Teaming, and LACP. Both Static Teaming and LACP are switch dependent.
Switch independent mode doesn't require network cards that are members of NIC Teaming to be connected with the same switch. They may be attached to different switches; however, that doesn't matter in this case.
Switch dependent mode requires all network cards that are members of NIC Teaming to be connected to the same switch. If you select this mode, it will offer you two operation modes, including:
- Static teaming—This requires the same configuration on the host and switches to identify which links are from the NIC Teaming mode.
- Link Aggregation Control Protocol (LACP)—This dynamically identifies the links between the host and the switch.
In addition, you can configure the load balancing mode and choose one of the three available options: Address Hash, Hyper-V Port, and Dynamic.
Address Hash mode helps to create a balance between network adapters that are members of NIC Teaming. It creates a hash based on the address component of the packet and then assigns the value to one of the adapters.
Hyper-V Port helps distribute traffic from switches to hosts on multiple links based on the MAC of the virtual machines.
Dynamic combines the address hash and Hyper-V port into a single mode. Outbound traffic is distributed based on a hash of TCP ports and IP addresses. Inbound traffic is distributed based on MAC.
You can combine different teaming modes with load-balancing modes.
Under the Standby adapter, you can choose whether you want to have all network cards active or put one of them in standby mode. Standby mode means that if one NIC fails, the second will take over network traffic.
- Once configured, click OK.
- Navigate to your network sharing center. You can do this by opening Run and typing ncpa.cpl. You will see that three network cards are joined to NIC Teaming. In my case, it's called 4sysops.
This NIC Team shares a single IP address.
NIC Teaming combines multiple physical and virtual network interfaces into a single logical virtual adapter called a NIC Team. It provides better performance, load balancing, and redundancy between network cards.
It supports different teaming and load-balancing modes. You can use all network cards that are members of NIC Teaming as active ones, or you can put one of them in standby mode.

The feature is disabled by default. You can enable it by enabling NIC Teaming, and then adding NICs to a single NIC Team.

It should be noted that NIC teaming is no longer the first choice for Hyper-V environments. Instead, switch-embedded teaming of the vSwitch should be used.
Thanks for the hint, Aaron.
Also note that SET switch embedded teaming now needs all network cards to be of the same Brand/Model/LinkSpeed. Pretty crummy limitation compared to the previous LBFO teaming.
Thanks for sharing your input, Jason.
I have a issue getting my teamed nic´s to work.
I have 2 NIC connected to different switches. One have static IP and one have DHCP.
When I team them, I loose connectivity to the server. I cannot connect using RDC on the static IP or DNS name.
PS. The DNS registration is assigned to the static IP.
When you add NICs to a team, they do not get individual properties (like IP addresses and all). Instead, you assign a static (or dynamic) IP address to virtual network (team) interface.
Thank you! Now it works as expected!
In the teaming mode section the screen shot picture shows the drop down for load balancing?
