This post shows how to change MAC Address in Windows by edit Windows Registry. Before you read this post, I suggest you to read Change MAC Address in Windows, Part I: Introduction first. Also, if you haven’t try to change MAC Address by using feature on a NIC, I recommend to try it before on Part II: Feature on NIC.
Before you read this post, I suggest you to read Change MAC Address in Windows, Part I: Introduction first.
MAC Address (Media Access Control) or physical address is a unique address assigned to NICs (Network Interface Card) by the manufacturer for identification. Even though MAC Address is a unique address which means that there shouldn’t be any MAC Address duplication occur in the world. But do you know that you can still change the MAC Address of NICs which is called MAC spoofing. It is a technique of hacking which you change the MAC Address to bypass access control lists on firewalls or routers.
Last time, I wrote an article show how to enable remote connection on SQL Server 2005 Express. Now SQL Server 2008 Express is released for a while, it doesn’t allow remote connection on default installation as on SQL Server 2005 Express. So you have to enable it manually.
If you have ever visited my blog before, you may noticed that I had written an article similar to this one already but I was using different software tool to reset administrator’s password. You can view the older post at How to reset administrator password on Windows using EBCD. Currently, the tool “EBCD” is already deprecated which means that the author doesn’t maintain this tool anymore. Hence, there will be no support, no new version of this tool.
Note: I have strike-through the old link above to indicate that it’s an old tool and I don’t recommend to use it anymore. But I want to keep it as an alternative and for reference.
Nessus vulnerability scanner is a tool which can discover and analyze vulnerabilities in the system so that IT staff can fix that holes and hence the system becomes more secure.

If you have a disconnected network from the Internet, you need to update the Nessus’s plugins manually.

If you have anti-virus installed on your PC and wonder whether your anti-virus is working or not. What would you do to test the anti-virus software? Ask a programmer to write a virus to destroy your PC? No, you wouldn’t want any harm on your PC, just only want to test the anti-virus software. Fortunately, there is a test file that you can create by yourself to test your anti-virus without causing any damage to your PC. The file was provided by EICAR, which stands for European Institute for Computer Antivirus Research, called the EICAR test file.
By default, Microsoft Internet Security & Acceleation Server (ISA) will block any connection between internal and external network. If you have Symantec AntiVirus and it needs to update definition (or signature) from internet through ISA, The ISA will block the connection so that the program can’t update the definition.
Have you ever need to block users using MSN or Yahoo Messenger? Or block them to using free email services? Or even block them to post anythings on web boards? Or block them to using bit torrent to download files? This topic can answer these questions by using Microsoft ISA Server 2006.
After completed part III, you have done basic configurations on ISA Server. In this part, you’re going to configure on client computer to be one of these types: SecureNAT Client, Firewall Client or Web Proxy Client. You can see more detail in topic below.
From part II, you have configured Network Topology. Now you need to create a policy rule to allow traffic pass through the ISA Server.
