Changing the MAC address in W2K and XP

Method 1:

This is depending on the type of Network Interface Card (NIC) you have. If you have a card that doesn’t support Clone MAC address, then you have to go to second method.

Go to Start->Settings->Control Panel and double click on Network and Dial-up Connections.

Right click on the NIC you want to change the MAC address and click on properties.

Under “General” tab, click on the “Configure” button

Click on “Advanced” tab

Under “Property section”, you should see an item called “Network Address” or “Locally Administered Address”, click on it.

On the right side, under “Value”, type in the New MAC address you want to assign to your NIC. Usually this value is entered without the “-“ between the MAC address numbers.

Goto command prompt and type in “ipconfig /all” or “net config rdr” to verify the changes. If the changes are not materialized, then use the second method.

If successful, reboot your systems.

Method 2:

This method requires some knowledge on the Windows Registry. If you are not familiar with Windows Registry, just use the SMAC tool to change the MAC addresses, or consult with a technical person before you attempt on the following steps. Also, make sure you have a good backup of your registry.

a. Goto command prompt and type “ipconfig /all”, and

I. Record the Description for the NIC you want to change.

II. Record the Physical Address for the NIC you want to change. Physical Address is the MAC Address

b. Goto command prompt and type “net config rdr”,
c. Remember the number between the long number (GUID) inside the { }. For example, in the above “net config rdr” output, for MAC address “00C095ECB793,” you should remember {1C9324AD-ADB7-4920-B02D-AB281838637A}. You can copy and paste it to the Notepad, that’s probably the easiest way. (See figure 2.)

d. Go to Start -> Run, type “regedt32” to start registry editor. Do not use “Regedit.”

e. Do a BACKUP of your registry in case you screw up the following steps. To do this

I. Click on “HKEY_LOCAL_MACHINE on Local Machine” sub-window

II. Click on the root key “HKEY_LOCAL_MACHINE”.

III. Click on the drop-down menu “Registry -> Save Subtree As” and save the backup registry in to a file. Keep this file in a safe place.

f. Go to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}. Double click on it to expand the tree. The subkeys are 4-digit numbers, which represent particular network adapters. You should see it starts with 0000, then 0001, 0002, 0003 and so on.

g. Go through each subkey that starts with 0000. Click on 0000, check DriverDesc keyword on the right to see if that’s the NIC you want to change the MAC address. The DriveDesc should match the Description you recorded from step (a.-I.). If you are not 100% sure about the DriverDesc, then you can verify by checking if the NetCfgInstanceID keyword value matches the GUID from step (c).
If there is no match, then move on to 0001, 0002, 0003, and so on, until you find the one you want. Usually 0000 contains the first NIC you installed on the computer.
In this demonstration, 0000 is the NIC I selected. (See figure 3.)

h. Once you selected the subkey (i.e. 0000), check if there is a keyword “NetworkAddress” exist in the right side of the window. (See figure 3.)

I. If “NetworkAddress” keyword does not exist, then create this new keyword:

i. Click on the drop down menu “Edit -> Add Value”.

ii. In the Add Value window, enter the following value then click OK. (See figure 4.)
Value Name: = NetworkAddress
Data Type: = REG_SZ

iii. String Editor window will pop up at this time (see figure 5.)

iv. Enter the new MAC address you want to modify. Then click OK.
(There should not be any “-” in this address. Your entry should only consist of 12 digits as seen in the figure 5.)

II. If “NetworkAddress” keyword exists, make sure it shows the keyword type is REG_SZ, and it should show as NetworkAddress:REG_SZ: . This keyword might not have a value at this time.

i. Double click on the keyword NetworkAddress and the String Editor window will pop up. (See Figure 5.)

ii. Enter the new MAC address you want to modify. Then click OK.
(There should not be any “-” in this address. Your entry should only consist of 12 digits

j. There are 2 ways to make the new MAC address active. Method I does not require a system reboot:

I. Goto Start->Setting->Control Panel, and double click on “Network Neighborhood”.
WARNING: Make sure you understand that you WILL lose the network connection after completing step “ii.” below, and
if you have a DHCP client, you will get a new IP address after completing step “iii.”

i. Select the Network Adaptor you just changed the MAC address.

ii. Right click on the selected Network Adaptor and click “Disable.”
Verify the status column for this adaptor changes to “Disabled”

iii. Right click on the selected Network Adaptor and click “Enable.”
Verify the status column for this adaptor changes to “Enabled”

iv. If for any reason it cannot be disabled or re-enabled, you have to
reboot your system to make the changes effective.

II. Reboot your Windows system.

k. Once completing step j (if rebooting the system, wait until the reboot is completed), go to command prompt, type “ipconfig /all” to confirm the new MAC address.

Restore The TRUE Hardware burned-in MAC Address:

Remove the entry you added:

If you followed Method 1, then go back to the advanced properties window and remove the entry you add.

If you followed Method 2, then remove the “NetworkAddress” keyword you added in the registry.

Use step (j) above to activate the change you make.

Once rebooted, go to command prompt, type “ipconfig /all” to confirm the original MAC address.

If MAC Address changes does not work:

If for whatever reason the MAC address cannot be changed using method 2, make sure you restore the registry setting by following the “Restore The TRUE Hardware burned-in MAC Address” instruction above. If necessary, restore the registry you just backed-up to get your system back to the original state. You can do this by clicking on the drop-down menu “Registry->Restore,” and restore your backup registry file.

or use SMAC

msconfig: Go to start, run “msconfig” without quotes. Click on startup tab. Uncheck the startup programs that are unwanted eg.dap,idman,msnmsg,realplay,qttask,realsched etc.
if u want U can disable all the programs,it wouldn’t effect the normal functioning of ur system. Then click “ok” n restart ur system. When the system is restarted a confirmation msg is displayed click ok again.

Clear startup: Go to start, programs, startup and delete all the programs present in it, these are only shortcuts so don’t worry while deleting.
Tip:- add ur favorite playlist to startup…go to “start, run, programs, startup” usually its empty, right click and paste ur playlist there n vo’la.

Less Desktop Icons: Delete all the icons of programs u don’t use regularly. Lesser the number of icons, faster is the desktop.

Minimum no. of processes: This should be done manually. Open the task manager and end the processes which are not system processes i.e., end the user processes. This method really helps speeds up ur system.

Sound displaying: Go to control panel, sound, select sounds tab ,in sound scheme select no sound scheme, do not save the pervious scheme. The unnecessary sounds which use up a lot of ram are disabled thus enhancing your ram.

Disk Cleanup and Defrag: Go to start, programs, accessories, system tools and run disk cleanup and defragment once a month.

Hiding Files in pics( u will b amazed ppl) December 18, 2006

# You will need the following.. Windows 2000 / XP
# Basic Knowledge of the Command Prompt
# WinRar

1. Gather your image and the files you wish to lodge into it. Here I have a meeting.txt which I will hide inside my toshow.jpg.
2. Add the files you want to hide into a new RAR archive. (so meeting.txt.rar created newly)
3. Open Command Prompt and go to the folder where your files are located, e.g., ‘C:\hidden’.
5. At command prompt type ‘copy /b toshow.jpg + meeting.txt.rar lizard.jpg’ (without quotes).
(toshow.jpg is the picture I want to show, meeting.txt.rar is the file to be hidden, and lizard.jpg is the file which contains both.
6. Now test the lizard.jpg by double clicking it, and verifying it still opens.
7. Now try opening that same lizard.jpg file from menu: file->open of WinRar. It will show the original hidden file meeting.txt.

Done !!!!!

Now lizard.jpg is a simple JPEG for others, but it contains a secret file meeting.txt for you !!!!!!!!!

Suppose you want to lock the folder games in d: which has the path D:\Games.In the same drive create a text file and type
ren games games.{21EC2020-3AEA-1069-A2DD-08002B30309D}
Now save this text file as loc.bat

create another text file and type in it
ren games.{21EC2020-3AEA-1069-A2DD-08002B30309D} games
Now save this text file as key.bat

Now you can see 2 batch files loc and key.Press loc and the folder games will change to control panel and you cannot view its contents.Press key and you will get back your original folder.

try it out!!!!!!!
