Xp operating system network card mac address modification method (a)

        You can right-click on the "Network Neighborhood" icon on the desktop and select "Properties". In the "Network Connection" dialog box that pops up, right click on the "Local Area Connection" icon and select "Properties". A "Local Area Connection Properties" dialog box, click the "Configure" button, select "Advanced", and select "network address" in the left column "Properties" (in fact, not all network cards, the description of the physical address is "network" Address", such as intel's network card is described by "locally administered address", as long as you can find the "value" option in the right column, then select the above single option in the right column "value" (non "Does not exist", you can enter the MAC address of the network card you want to change in the box on the right, in the form of "000b6af6f4f9". Click the "OK" button, the modification is complete. However, some network cards do not have this option, do not Anxious, you can first try to update the driver of the network card. Under normal circumstances, this option will appear after updating the driver. But there are still special circumstances. No matter how you change it, there is no such option. What should I do? Then look down, the following method can be said to be omnipotent. Step 1, click "Start", select "Run", type "regedit" to call up the registration. Table 2. In the second step, under the primary key of hkey_local_machine\\\\system\\\\currentcontrolset\\\\control\\\\class\\\\{4d36e972-e325-11ce-bfc1-08002be10318}\\\\0000, 0001, 0002, etc., find driveresc, the content is The description of the modified network card, such as the intel network card, will be described as "intel(r) pro/100+ management adapter", and the 3com network card will be described as "3com etherlink xl 10/100 pci for complete pc management nic (3c905c- Tx)", etc. The location of the above mentioned options for the description of the network card is related to the network card itself and the operating system. Different network cards may appear under different primary keys, and the same network card uses different versions of the operating system (such as oem Versions, vol or vlk, etc.) will also appear in different locations. The task of this step is to find the primary key that contains the description of the network card. Select the primary key found in the second step, add a string in the right column, name it "network address", and set its value to the mac address to be changed, in the form of "000b6af6f4f9". In this step, modify the NIC physics. The task of the address can be said to be completed. Some network cards need to be restarted to work normally, and some only need a little bit of time to "react". The following steps are for the convenience of modifying the physical address later. If the reader no longer needs to modify it again, it can be stopped here. In step 4, add a primary key named "networkaddress" under "First key selected first key" \\\ di\\\\params, which will generally generate a "default" string in the right column. , set its value to the mac address you want to modify, in the form of "000b6af6f4f9". If you don't have this string, you can add this string yourself. This step is to set an initial mac address for the NIC. In step 5, continue to add a string named "optional" under the

primary key of "networkaddress", and set the value to "1". Then select the "network address" item in the advanced properties of the NIC. The "Nothing" option appears on the right. In step 6, under the primary key of "networkaddress", continue to add a string named "paramdesc", which is used to specify the description of the "networkaddress" primary key, and its value can be named by itself, such as "network address", so that the advanced in the network card The "network address" option will appear in the attribute, which is the new item "networkaddress" just added in the registry. You can modify the mac address here later. Step 7, restart the computer (not necessarily restart, but depending on the requirements of different network cards, however, there is no error in the restart.), follow the first method to find the "advanced" option to find the "attribute" The "network address" option is available in the column. Now the reader can directly modify the mac address or restore the original address.
