SMAC MAC Address Changer 1.2

SMAC is a powerful, yet an easy-to-use and intuitive Windows MAC Address Modifying Utility (MAC Address spoofing) which allows users to change MAC address for almost any Network Interface Cards (NIC) on the Windows 2000, XP, and 2003 Server systems, regardless of whether the manufactures allow this option or not.

SMAC does not change the hardware burned-in MAC addresses. It is not necessary. SMAC changes the "software based" MAC addresses on the Windows 2000, XP, and 2003 Server systems, and the new MAC addresses you change will sustain from reboots.

Features:
- Modify MAC address in seconds on your Windows 2000, XP and 2003 systems.
- User-Friendly Windows user interface (GUI.)
- Intuitive and simple-to-use GUI layout. (Check out the SMAC screenshot.)
- Display network information of your available network adapters in one screen.
- Capable of displaying ONLY the active network adapters.
- Built-in logging capability for you to track MAC address modification activities.
(Of course you can clean the log file at any time.)
- Protect your privacy.

Benefits and Applications of spoofing MAC address:
- Perform Security Vulnerability Testing, Penetration Testing on MAC Address based Authentication and Authorization Systems, i.e. Wireless Access Points. (Disclaimer: Authorization to perform these tests must be obtained from the system owner(s).)
- Build "TRUE" Stand-by (offline) systems with the EXACT same CompterName, IP, and MAC ADDRESSES as the Primary Systems. If Stand-by systems should be put online, NO arp table refresh is necessary, which eliminates extra downtime.
- Some online Game Players (Gamers) require changing the MAC addresses to fix IP problems for some reason...
- Build High-Availability solutions. For example, some firewalls that run on multi-port NICs (i.e. quad port NIC) require the same MAC address for every port.
- Troubleshoot Network problems. Arp Tables, Routering, Switching, ...
- Troubleshoot system problems
- Test network management tools
- Test incident response procedures on simulated network problems
- Test Intrusion Detection Systems (IDS), whether they are Host and Network Based IDS.
- If for whatever reason you need to keep the same MAC address as your old NIC, but your old NIC failed...
- Some software can ONLY be installed and run on the systems with pre-defined MAC address in the license file. If you need to install one of these software to another system with a different Network Interface Card (NIC) because your NIC is broken, SMAC will come handy. However, you are responsible to comply with the software vendors licensing agreement.
- Some Cable Modem ISPs assign IP addresses base on the PCs MAC addresses. For whatever reason, if you need to swap 2 PCs regularly to connect to the cable modem, it would be a lot easier to change the MAC addresses rather than to change Network Interface Card (NIC). (You need to check with your ISP and make sure you are not violating any service agreements.)
