Boot up with DOS and delete the sam.exe and sam.log files from Windows\system32\config in your hard drive. Now when you boot up in NT the password on your built-in administrator account which will be blank (i.e No password). This solution works only if your hard drive is FAT kind.
Method 2
Step 1. Put your hard disk of your computer in any other pc .
Step 2. Boot that computer and use your hard disk as a secondary hard disk (D'nt boot as primary hard disk ).
Step 3. Then open that drive in which the victim’s window(or your window) is installed.
Step 4. Go to location windows->system32->config
Step 5. And delete SAM.exe and SAM.log
Step 6. Now remove hard disk and put in your computer.
Step 7. And boot your computer

0 L3 Switches
Level 3 Switches (or L3) are devices used for networking and routing. They are rated as being high-performance and cost effective devices. Some of you might be confused by the name because Layer 3 of the OSI model is usually used by routers and Layer 2 by switches
Here are a couple of important characteristics of the L3 Switches:
Compact design which can easily be fitted in any rack designed to house such network equipment
Silent because there are only a couple of models that use a fan, most of the L3 Switches do not need such cooling systems
Highly efficient due to the awareness of IP multicast
Usually comes at a lower cost as compared to other types of routers
L3 switches are very common because of the above mentioned characteristic, but the most important benefit that it can provide with is the IP multicast awareness. This feature is very useful because it does not waste the bandwidth of the network by distributing the signal to all ports. The switch is able to detect the ports that require the signal to be transmitted and only sends it to those ports. To make it easier to understand, it would be very similar to sending and SMS to your entire contact list, even if 50 percent of the numbers there are not valid anymore. So, you would be wasting money by doing that.
Ok, let’s see what type of hardware the L3 switches use. In simple terms, the hardware you can find in this type of switches is a combination of routers and switches, but the software logic part of the router is replaced with a hardware version to make sure that performance is at it’s best.
You can probably see that the L3 Switches have the same external design as the other types of switches and routers, with ports at the back and LED lights at the front. The Ethernet ports are used to connect the cables to the switch and the LED lights can indicate a series of functions and other information about the functioning of the switch.
Another difference between the L3 Switches and the traditional router would be the lack of the WAN port and other wide area network features that you can see implemented in all normal routers. What does this mean? This means that you can only use L3 switches in specific applications. In some cases, companies outright discard routers and use these kind of switches. This is due to the primary fact that a switch integrates better with the proxy servers implemented in the company network.

0 Facebook checks in to location-based services with Places
Facebook CEO Mark Zuckerberg late on Wednesday announced the company's latest creation, a foray into the world of location-based services called Facebook Places.
"This is going to be a really fun and interesting summer," said Zuckerberg at the start of the evening. "We've got a lot of new products coming out." The first of these new products -- Places -- is a smartphone-based service that takes on much of the functionality provided by existing services such as Foursquare and Yelp.
Michael Sharon, Facebook's product manager for Places, demonstrated the service's capabilities, most of which appear functionally identical to the features already popularized by Foursquare. Through an updated version of the iPhone app or by browsing to touch.facebook.com on a mobile browser, users will find a main menu that shows nearby friends and offers a list of nearby places to check into.
Choose a place from the list and tap the "check in" button to check in, or tap the plus symbol to add a new place, and users will see a security notice explaining that they're about to share their location. The service also includes the ability to tag friends who are in the same location and check them in at the same time because, as Sharon explained, not everyone has a smartphone that supports Places yet.
Privacy controls
In light of recent concerns over Facebook user privacy, the company made a point of highlighting Places' security features. By default, check-ins are visible to friends only, though this setting is customizable to allow broader sharing or to restrict it down to just a few specific people.
Users will only be able to tag people who are on their friends lists, and then only when they first check into a place. This ostensibly limits the chances of mischief with the service, particularly because the only way to check a friend into a potentially embarrassing location will be to check oneself in as well.
Users will have the ability to remove themselves from any tag, just as with the existing photo sharing service. Additionally, users can choose to opt out of letting others tag them in Places.
Places will also include a reporting feature that will allow users to report location listings that are erroneous, offensive, or out of date. As of Thursday, Facebook will launch a read API that lets people read check-ins and find out more about a place. A write API and a search API are currently in beta in beta testing and will be rolled out to developers soon.
Facebook partners
When Sharon finished his overview of the service, he invited representatives from several popular location-based services to the stage to describe their companies' new features that integrate with Facebook Places.
Scott Raymond, CEO of Gowalla; Holger Luedorf, Foursquare VP of mobile & partnerships; Eric Singley, director of mobile products at Yelp; and Keith Lee, CEO of Booyah stepped up to the podium to talk about how they perceive the new service. Unsurprisingly, all four sounded bullish on Places, though at times the tone seemed a bit desperate.
Holger Luedorf of Foursquare used his time at the podium to answer the question on everybody's mind: "This basically validates that we're onto something and that we're adding value," said Lueforf, focusing on the positive. "We're looking forward to working with the Facebook team."
