Modifying the NIC address breaks through some restrictions on Mac binding services and breaks through blocking to cope with viruses.

Try to modify the NIC address of your machine to the MAC address that someone else can access the Internet normally. NIC address view start-run-cmd-ipconfig/all note that there are two NICs in The Notebook. One is wireless, and the other is wired. You need to modify the method by right-clicking on the local connection.-properties-General- configure-advanced-local management address-enter the value as another person's NIC address and then you can assign it to another person's IP address. If you try to access the Internet, you can find the person in charge of Network Management in your company and ask if you have set IP access permission filtering to restrict the access to the network card address or IP address.

The chance to modify the address of the network card. txt is like a hair on the bald head. If you catch it, you can't catch it. I spoke to you for 10 minutes but didn't argue with you. Then, there must be a person between us who is so hypocritical! A mistake is a temporary regret, and a miss is a permanent regret. Encounter is fate, mutual understanding is a part, mutual love is an agreement, and mutual observation is true love. The MAC address is the unique identifier of the network card. Generally, it cannot be modified at will. Any network card has a MAC address with a length of 48 bits, at the beginning, this address was burned in by the NIC manufacturer. Theoretically, the MAC address is globally unique and will not cause any conflict. However, due to the special nature of the operating system, we can modify some parameters so that the MAC address of the NIC recognized by the operating system can display the expected value, so as to modify the MAC address. In actual use, the modification of the MAC address mainly results in breakthroughs in dealing with viruses and some Mac binding services. What commands can we use to query the MAC address of the Local Machine? First, go to the operating system, choose "start"> "run", Enter cmd, and press enter to enter the Command Prompt window. Enter the ipconfig/all command in the Command Prompt window. The following prompt is displayed in the displayed information. Physical address ......: The address following 00-08-02-6b-a3-1a is the MAC address of the NIC. 2. Modify the MAC address of the NIC parameters. Next, I will introduce how to modify the MAC address of the NIC from different aspects. The first step is to modify the MAC address from the NIC parameters, this method is the simplest and most direct method, which can be easily completed by clicking the mouse. Step 1: Go to the desktop system, right-click the "Network Neighbor" icon, and select Properties. Step 2: In the Open Properties window, find the "local connection" icon, right-click it, and select "properties". This will open the NIC Properties window. Step 3: click the "Configure" button in the upper right corner of the NIC Properties window to directly open the NIC configuration information. Click the "advanced" tab, find the "local management address" column under it, select "value" on the right, and enter the MAC address information of the NIC You Want To modify. Remember that it is a 12-digit number, for example, 111111111111. After the modification, click "OK" to make the change take effect. In this way, the MAC address of the NIC is successfully modified to 111111111111. Of course, this method is not suitable for all types of NICs. This method can be used only for some NICs, especially those with their own management functions. Of course, the judgment method is also very simple, that is, if the "local management address" can be found in the "advanced" tab of the NIC attribute, the MAC address information can be modified, if it cannot be found, you cannot use this method to modify the MAC address. In general, the NIC of the laptop and nic of some brand machines can be used to modify the MAC address. 3. Modify the MAC address information of the NIC through the registry. If the NIC does not have the function of managing parameters, we can only modify the MAC address information through the registry. Next I will introduce it step by step. Step 1: First confirm the device instance id of the network adapter or the network adapter description. For this information, you can view the network adapter name in "Device Manager. (4) Step 2: Click Start> RUN> enter regedit and press enter to enter the Registry Editor. Step 3: in the registry, find driverdesc under the primary key of hkey_local_machinesystemcurrentcontrolsetcontrolclass0, 0001, 0002, and so on. The content is the description of the NIC to be modified, for example, "Intel (r) pro/100 ve network connection ". For example, in hkey_local_machinesystemcurrentcontrolsetcontrolclass3, The driverdesc content is "Intel (r) Pro/100 ve network connection ". Step 4: Add a string named networkaddress under 0003 with the value set to the MAC address you want to modify (note that the address is still written continuously ). For example, I enter 111111111111. Step 5: Add a primary key named networkaddress to the ndiparams and add a string named default under the primary key. The value of this string is the MAC address you want to set and it must be written continuously, for example, 111111111111. Note: In fact, this is only the "Initial Value" in the advanced attribute mentioned later. The actual MAC address used depends on the networkaddress parameter mentioned in Step 4. Once this parameter is set, in the future, the value in the advanced attribute is the value given by networkaddress rather than the default value. Step 6: Add a string named paramdesc under the primary key of networkaddress. The function is to specify the description of the primary key of networkaddress. The value can be named by yourself, for example, "network address ", in this way, the network address option appears in the Advanced properties of the network card. Add a string named optional with the value set to "1". In this way, when you select the network address option in the Advanced properties of the network adapter, the "nonexistent" option will appear on the right. Step 7: restart your computer, open the properties of the network neighbor, double-click the corresponding Nic item, and you will find a network address advanced setting item, it can be used to directly modify the MAC address or restore the original address (the selected address does not exist ). This method is actually used to modify the MAC address Nic by modifying the "Nic Parameters, after this method is added, if we do not have the "local management address" in the NIC configuration parameters, we can also see it to easily modify the MAC address of the NIC. 1.
