Hi All, We have an AD to authenticate for wireless users. In AD, we have specified to block the user if the password is entered wrongly for more than 3 times. The problem is some of them are using other user ID and locking the accounts. I have gotten the MAC address of the user. Can anyone please. M AC address (Media Access Control address) is a quasi-unique identifier consists of a six byte number that attached to most network adapter card or network interface card (NIC). As such, all network cards, whether it's of Ethernet NIC, Gigabit Ethernet NIC or wireless 802.11a/b/g/n/ac WiFi or HiperLAN adapter, should have different MAC addresses, which also known as Ethernet Hardware.

In this topic, we discuss ways to troubleshoot NIC Teaming, such as hardware and physical switch securities. When hardware implementations of standard protocols don't conform to specifications, NIC Teaming performance might be affected. Also, depending on the configuration, NIC Teaming may send packets from the same IP address with multiple MAC addresses tripping up security features on the physical switch.
Hardware that doesn't conform to specification
During normal operation, NIC Teaming may send packets from the same IP address, yet with multiple MAC addresses. According to protocol standards, the receivers of these packets must resolve the IP address of the host or VM to a specific MAC address rather than responding to the MAC address from the receiving packet. Clients that correctly implement the address resolution protocols (ARP and NDP) send packets with the correct destination MAC addresses—that is, the MAC address of the VM or host that owns that IP address.
Some embedded hardware does not correctly implement the address resolution protocols, and also might not explicitly resolve an IP address to a MAC address using ARP or NDP. For example, a storage area network (SAN) controller might perform in this manner. Non-conforming devices copy the source MAC address from a received packet and then use it as the destination MAC address in the corresponding outgoing packets, resulting in packets being sent to the wrong destination MAC address. Because of this, the packets are dropped by the Hyper-V Virtual Switch because they don't match any known destination.
If you are having trouble connecting to SAN controllers or other embedded hardware, you should take packet captures to determine if your hardware is correctly implementing ARP or NDP, and contact your hardware vendor for support.
Physical switch security features
Depending on the configuration, NIC Teaming may send packets from the same IP address with multiple source MAC addresses tripping up security features on the physical switch. For example, Dynamic ARP inspection or IP source guard, especially if the physical switch is not aware that the ports are part of a team, which occurs when you configure NIC Teaming in Switch Independent mode. Inspect the switch logs to determine if switch security features are causing connectivity problems.
Disabling and enabling network adapters by using Windows PowerShell
A common reason for a NIC Team to fail is that the team interface is disabled, and in many cases, by accident when running a sequence of commands. This particular sequence of commands does not enable all of the NetAdapters disabled because disabling all of the underlying physical members of NICs removes the NIC team interface.
In this case, the NIC team interface no longer shows in Get-NetAdapter, and because of this, Enable-NetAdapter * does not enable the NIC Team. The Enable-NetAdapter * command does, however, enable the member NICs, which then (after a short time) recreates the team interface. The team interface remains in the 'disabled' state until re-enabled, allowing network traffic to begin flowing.
The following Windows PowerShell sequence of commands may disable the team interface by accident:

NIC Teaming: In this topic, we give you an overview of Network Interface Card (NIC) Teaming in Windows Server 2016. NIC Teaming allows you to group between one and 32 physical Ethernet network adapters into one or more software-based virtual network adapters. These virtual network adapters provide fast performance and fault tolerance in the event of a network adapter failure.
NIC Teaming MAC address use and management: When you configure a NIC Team with switch independent mode and either address hash or dynamic load distribution, the team uses the media access control (MAC) address of the primary NIC Team member on outbound traffic. The primary NIC Team member is a network adapter selected by the operating system from the initial set of team members.

We also give you details about the Standby adapter setting and the Primary team interface property. If you have at least two network adapters in a NIC Team, you do not need to designate a Standby adapter for fault tolerance.

Many people have a wrong conception that changing MAC Address of a computer is not possible or it requires a complex software. But it is not true. Changing MAC or Physical address of your computer is very simple. MAC (Media Access Control) address, Ethernet Hardware Address (EHA), hardware address, adapter address or physical address is a quasi-unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number. Although intended to be a permanent and globally unique identification, it is possible to change the MAC address on most of today's hardware, an action often referred to as MAC spoofing.
Now getting to the point we can change MAC by using your Windows Registry Editor. The method has been successfully tested in different Wired Ethernet Adapters, Wireless Adapters etc.
Follow the steps below and your MAC will be changed in seconds:
Step 1: Open Registry Editor (Press Start + R, Type regedit and Enter). If you get a message like 'Your Registry Editor Has Been Disabled By Your Administrator' then you need to enable it. To Enable Registry Editor Visit: How to enable registry Editor
Step 2: After opening Registry Editor successfully, see the left pane of your registry editor. Capture one pro macos catalina. You can find a series of registry keys. You have to follow the path as:
HKEY_LOCAL_MACHINESystemCurrentControlSetControlClass{4D36E972-E325-xxxx}
For the last key search for the red highlighted part in your Editor. You can refer the image below:

Step 3: After opening the last Key you will see a set of keys like 0000, 0001, 0002 etc. You have to open each key and search for values which corresponds to your network adapter. For example, I have an Intel(R) PRO/100 VE Network Connection. So in the right side of the editor i found a value which is containing this name. This is how we identify the key for the network adapter. For me i got the key in 0007.
Step 4: Now search for the value NetworkAddress inside the key you have found. If you cant find it right click and create a new String Value of the name NetworkAddress.
Step 5: Now change the value as your MAC Address. After Changing the value you can close Registry Editor.

Step 6: Now Go to Network Connections and Disable your Adapter. Right Click and select Disable
After it is disabled Double click on the Network Adapter and it will Enable it.
Step 7: Now go to status of the Adapter and Check The MAC address.
You will find your desired MAC Address. Now you have changed your Physical Address successfully.
Important:
1. This method Will not work for Windows Network Bridges.
2. If you keep an invalid MAC address value then your Adapter will not function properly.
