SMAC Frequently Asked Questions
(FAQ)
What does SMAC stand for? (Back
to Top)
Spoof MAC
Address (SpoofMAC)
What systems do SMAC support? (Back
to Top)
SMAC supports Windows 2000, XP, 2003, VISTA,
2008.
What
MAC Address should I spoof?
Set the MAC Address to an address with the 2nd digit as "2",
which makes the first 2 digits as 02, 12, 22, 32, 42, etc. For example, here are
a couple of valid MAC addresses: 1) 02-93-84-91-29-01; 2) 32-71-93-EC-51-AF.
You may use Random for most of the wired network adapters.
However if you encounter problems, use a MAC Address with "2" as the 2nd digit.
Why can't I get SMAC to work?
(Back to Top)
For Windows 2000, XP, 2003:
In order to use SMAC, you MUST login
with an administrator level user account. You MUST have READ and WRITE access to the registry
of your Windows 2000, XP, 2003, VISTA, 2008, and Windows 7 system.
- Be sure that you are using a valid
Singlecast (Unicast) MAC Address. The second hex digit of the first
octet (reading left to right) should be even (zero is considered
even). You can get more information on MAC Address from this
link:
IANA
Number Assignments database.
- Be sure that you are logged-on with an
administrative user account.
- Be sure that you are using a Network
Adapter that is certified by Microsoft for use with you version of
Windows. You can check
Microsoft's Hardware Compatibility List (HCL) or
Tested Products List.
For Windows 7, VISTA, 2008:
When you start SMAC program, you must start
it as the administrator. You could do this by right click on the SMAC
program icon and click on "Run as Administrator".
- Be sure that you are using a valid
Singlecast (Unicast) MAC Address. The second hex digit of the first
octet (reading left to right) should be even (zero is considered
even). You can get more information on MAC Address from this
link:
IANA
Number Assignments database.
- Be sure that you are logged-on with
an administrative user account and, for Windows Vista, both the
installation and SMAC program should also be Run As Administrator.
This can be set through the shortcut properties menu or by
right-clicking on the executable or shortcut.
- Be sure that you are using a Network
Adapter that is certified by Microsoft for use with you version of
Windows. You can check
Microsoft's Hardware Compatibility List (HCL)
or Tested Products List. You will likely need to update the driver
to a VISTA compatible driver if you have upgraded your operating
from Windows XP to VISTA. Otherwise, you may need to install a
new Network Adapter that is Certified for Windows VISTA.
Please confirm the Windows VISTA Compatibility Certification with
the network adapter manufacturer if necessary.
I just updated the new MAC Address but my network
adapter doesn't show
the new MAC address? (Back
to Top)
- If you have problem changing the MAC Address, follow this
direction: Some Wireless NIC only accepts MAC Address with the 2nd digit
that sets as "2", which makes the first digit as 02, 12, 22, 32, 42, etc.
For example, here are a couple of valid MAC addresses: 1) 02-93-84-91-29-01;
2) 32-71-93-EC-51-AF.
- What Operating Systems are you running?
SMAC supports Windows 2000, XP, 2003, and VISTA systems.
- Are you logged in as the administrator of
your computer? You must log in with administrator level account in
order to get SMAC to work.
-
Did you try to reboot
after update the MAC Address with a system administrator account?
Usually you don't need to reboot, but in some cases, rebooting the system
will resolve this problem.
- When changing MAC address, you MUST
assign MAC addresses according to
IANA
Number Assignments database. For example,
"00-00-00-00-00-00" is not a valid MAC address, therefore, even
though you can update this address, it may be rejected by the NIC device
driver because it is not valid, and TRUE MAC address will be used
instead. Otherwise, "00-00-00-00-00-00" may be accepted by the
NIC device driver, however, the device will not function. You can find the information at
http://www.iana.org/assignments/ethernet-numbers.
The latest MAC address Organization Unique Identifier (OUI) listing is
available at
http://standards.ieee.org/regauth/oui/oui.txt.
- Is your network adapter certified for the
version of Windows operating system you are using? You can check with
your network manufacturer, or check out the Microsoft hardware compatibility
list (HCL) URL:

to "0C-0C-0C-0C-0C-0C." SMAC Full version allows you to change to any MAC
addresses you wish.
How do I remove the
spoofed MAC Address? (Back to Top)
On the SMAC screen, click on "Remove MAC" to remove the spoofed MAC address
for the selected network adapter. You still require to disable then
re-enable the affected network adapter, or simply reboot.
Can
I remove the spoofed MAC Address using the SMAC Evaluation Edition?

Yes, absolutely! On the SMAC Evaluation Edition, click on "Remove MAC" to remove
the spoofed MAC address for the selected network adapter. You still
require to disable then re-enable the affected network adapter, or simply
reboot.
I can only see "MAC Bridge Miniport" listed
as my adapter when running SMAC on Windows XP, Why?
(Back to Top)
In Windows XP ( and ONLY XP,) Microsoft have decided that it would be
easier to have a single MAC address for all devices in your computer if you
choose to do that, but this causes problems. This shows itself when you do
your 'ipconfig /all' command and the description line for the adapter is "MAC
Bridge Miniport." To fix this you need
to unbridge your ethernet adapter (don't worry if that
sounds very technical, the simple instructions are below so just
follow them).
---------------------
MAC Bridge Miniport problem for users of Windows XP only:
Remove your Network Card from the MAC Bridge Miniport by doing this:
1. Click on Start..Control Panel and then on Network Connections
2. Right-click on your Local Area Connection and choose Remove from
Bridge
3. Right-click Network Bridge and choose the Disable option
4. Click on as many OK boxes to get you back to the normal screen
(you may or may not need to reboot)
5. Now type "ipconfig /all" again in a command window and you should
see your Network Card and its proper MAC address. That is the MAC
address for your Network Adapter.
-------------------
This should resolve the problems of changing MAC Address in XP.
Does SMAC
work with VMWare virtual network adapters? (Back
to Top)
In the newer version of VMWare, SMAC users reported that it worked,
however, there is no gaurantee. The older version of VMWare does not read MAC address information from the
registry. According to the information on the VMWare website, it reads the MAC address information from the configuration
file (.VMX). Please refer to the VMWare website for more details.
Can
I change MAC addresses on "inactive" network adapters? (Back
to Top)
Yes. However, the newly spoofed MAC address will not take effect until the
network adapter is activated. For MAC address activation process, please
read the readme file.
Can SMAC work on my cable modem? (Back
to Top)
SMAC supports Windows 2000, XP, 2003, and VISTA
.
Can I have 1 MAC Address assigned to more
than 1 Network Adapter? (Back to Top)
Base on the way TCP/IP protocal, there should be 1 MAC address assign to 1
network adapter, and 1 MAC address for each IP address. If you have 1
MAC address assigned to more than 1 network adapter, you might experience
network problems.
When starting SMAC, why am I prompted to load a
Microsoft Office CD? (Back to Top)
SMAC does not actually use Microsoft Office. However,
SMAC does use the Microsoft Common Control component (Mscomctl.ocx) for
certain dialog features. This is a standard Microsoft file that is frequently
upgraded by applications including Microsoft Office. This is a known Office
2000 issue that has several causes. One cause is that Office was
installed on Windows 2000 under a non-administrative context. The fact
is that when Office installed the Mscomctl.ocx file, it did not properly
register the file with Windows. Therefore, when launching any third party
applications that reference the control, Windows will either prompt for the
Office CD to complete the installation or generate an error.
The solution is to load the Office CD when prompted and allow Office to
complete the installation. If you receive a 1706 error instead of
the CD prompt, you must login with an administrator account, start the
affected application and load the Office CD when prompted.
Why
do I get the message "SMAC has determined that you have insufficient
registry access..."? (Back to Top)
For Windows 2000, XP, 2003:
In order to use SMAC, you MUST login
with an administrator level user account. You MUST have READ and WRITE access to the registry
of your Windows 2000, XP, 2003, and VISTA system.
For Windows VISTA:
When you start SMAC program, you must start
it as the administrator. You could do this by right click on the SMAC
program icon and click on "Run as Administrator".
