When a network infrastructure includes router-based firewalls, the function of the firewall, which is to silently discard traffic that the firewall has not been configured to forward, can impair specific networking functions. For example, if a firewall between two Microsoft Windows Active Directory directory service domain controllers has not been configured to allow all of the different types of traffic that domain controllers use to synchronize the Active Directory database, replication can fail. When troubleshooting networking functions and reachability, a common step is to use the Ping tool (Ping.exe) and ping one computer from another. However, the Ping tool uses Internet Control Message...

Let me start off by saying that my home has been robbed. I was at work and got a call from my wife asking me if I had taken the VCR to be repaired. I knew right away that we had been robbed. That was the last time as we have since had a home security system installed.What I didn't know is, there are different types of security systems and not all security systems are created equally.Let me start with the type that I have personally. Mine is a monitoring system which is attached to an alarm built into your doors and windows. The more areas in your house you have the alarms installed in, the more expensive the installation, unless the monitoring company has a special offer. In our case we got...

Data loss is the biggest concern of every computer user. It is terrifying to lose hours or days of work just because some software malfunctioned on your PC. While system restore is built into your operating system, Windows System Restore only protects system files. It does not recover data, user settings or programs if Windows does not start up. Here's where RollBack Rx saves the day. Even if your Windows is corrupted and you are facing the dreaded "blue screen of death", Rollback Rx can still restore computer settings. The reason for this is that RollBack installs below Windows, letting you roll back to any of the snapshots it took prior to the problem point. You don't have to lose any data right...

Gas detectors can be found in all walks of life, from food processing plants to parking garages, from airplanes to casinos. Any place that can have a potential lack of oxygen or presence of a toxic gas needs a gas detector present to monitor the safety of people. Some common uses during field projects are: confined space entry, well drilling, soil screening, area mintoring, worker safety, indoor air quality, and leak detection. Gas detectors have a variety designs; pager size units, handheld datalogging units, Stand alone area monitors, and wall mount fixed systems.Here are some gas detection basics: 1ppm is one part in 1,000,000 parts.Generally ppm (parts per million) is the lowest unit of...

Digital cameras are basically the same as film cameras in their handling. They both have a lens to focus the specific image, a shutter to let light inside the camera, and an aperture to control the amount of light which enters the camera.The differences between digital and traditional photography happen to be after the light enters the camera. A traditional camera captures the images on film, while a digital camera captures the image on an image sensor.Image sensors are electronic devices made up of an array of electrodes (or photosites) which calculate light intensity. The most universally recognized type of image sensor for digital cameras is the CCD (Charge-Coupled Device) although others such as...

There are two measured elements that determine your internet connection speed. They are: The download rate, and the upload rate of data measured in bits per seconds. Usually, it is expressed in Kilobits per second.A bit is the smallest piece of data that can be stored in a computer. The bit can be either "0" or "1". The byte is eight bits. Example of a byte and bits are the following:bit= 0 or 1byte=8 bits1 byte=10011101 (eight bits)A single charcter needs one byte or eight bits to be stored in a computer. So, when the data rate is 1 byte/sec, that means one character per second is the rate at which data is transferred through your connection.This is very slow, and only intended for an...

Your CCNA certification exam is likely going to contain questions about Telnet, an application-level protocol that allows remote communication between two networking devices. With Telnet use being as common as it is, you had better know the details of how to configure it in order to pass your CCNA exam and to work in real-world networks.The basic concept is pretty simple - we want to configure R1, but we're at R2. If we telnet successfully to R1, we will be able to configure R1 if we've been given the proper permission levels. In this CCNA case study, R2 has an IP address of 172.12.123.2 and R1 an address of 172.12.123.1. Let's try to telnet from R2 to R1.R2#telnet 172.12.123.1Trying 172.12.123...

For many years the seat belt was relied upon for safety in automobiles. Many people debated whether seat belts were safe or not but over time many states made wearing seat belts mandatory. Statistics have proven that seat belts have saved lives in accidents everywhere. The safety belt is now mandatory, due to a primary or secondary law, in all states except New Hampshire. With most everyone now agreeing to the benefits of using a seat belt, carmakers have stepped up their safety standards to use technology to its advantage and developed air bags.In the 1980's the first air bag appeared in automobiles. In 1998 all new cars were required to have frontal air bags on both driver and passenger sides...

An Associated Press (AP) report recently stated that security products still sell despite the widespread availability of free software. Falling under the category of security would be anti virus software, anti spyware software, email spam blockers, firewalls and the like. The article points out that many internet service providers give out some form of free versions of these computer security products but still, security vendors are moving forward with the release of their latest line of products.Consumer behavior can sometimes be an extremely complicated puzzle to analyze. But clearly, this news article actually reflects a seriousness among consumers in protecting their personal computers. A few...

How do window cleaning franchise businesses start? It is a fascinating case study indeed, as most all window cleaning businesses start from such humble beginnings; a bucket of water, a sharp entrepreneur and a quality squeegee. I never thought in a million years I would ever enter the Window Washing Industry. I hate washing windows, probably because I suck at it. Anyway our company The Car Wash Guys Franchise Systems; was featured in a PBS Special on TV on a one-hour program. was viewed by 20 million American people. That night I got a call from a Chiropractor in Tucson. We talked from 8 pm until 5 am and we discussed all kinds of stuff. Two years went bye, then one day I was sitting a...

I was reading a management development article the other day and learned that if I wanted to succeed, I should look to persons who have succeeded before me, and do what they did. Seemed easy enough. I just needed to identify some marketing geniuses and I would be set. I pondered long and hard who I wanted to put on my list that I would emulate. Who had stood the test of time and was still standing?I was not getting very far, and my list was pretty short, so I headed off to Starbucks. Maybe a grande latte, with a double shot, would help jolt my memory. I was standing at the coffee bar waiting for a sleeve when I saw a rather peculiar bracelet on the barista's wrist.WWJD was all it said."What the heck...

If you read the internet and all of the websites dedicated to Asp.Net you will inevitably read about the wonders of the DataGrid, DataList, and Repeater controls. While each of these has its place, if you are only displaying data there is a much faster and more efficient means to do so.Let's say you have a page that displays articles based on a query string. Take my article pages for instance. Each article is stored in a database and displayed on the page based on the unique id of the article as stored in the database.A normal asp page execution procedure goes something like this. The code queries the database based on the Article I.D. and then brings back that information to the page where you...

Many articles have been written on the subject of Harry Potter and his remarkable appeal to the mass market, but that's not going to stop me putting in my five cents on the subject.I came to Harry Potter late myself, having dismissed the books as something for children for several years. It was a silly dismissal on my part since I can name several children's books that I still happily read. However, a couple of years ago the staggering media coverage of the movies forced me to read the books to see what all the fuss was about. Since then, like most everyone else, I have been captivated.I have read all of the Harry Potter books in order, watched the movies and read many articles about various aspects...

They were history for over a decade, Damask and Toile fabric looks. Their look was heavy and dated, screamed 1960's decadence and 1970's over-the-top decorating. An interesting thing happened in the last couple of years, they underwent a make over, I would even consider the new softer, less intense presentation that these prints can offer a window opening, chair or room. Traditional designer is very 2006, Trad is Rad!-Damask is actually a weaving technique of threads that creates a reversible pattern.-The softer look of today's Damask is often a white background color over-layed with one foreground color. To Rad a room select contemporary furniture pieces and use a new Damask.-Don't go overboard...

"A giraffe can kiss the clouds because it is long, and God is long," says Tori, age 6. Well, the Psalmist wrote that "with an outstretched arm" God's mercy endures forever. I suppose "outstretched" qualifies as long."God created the horse so people could ride on it," says Jacob, 7. "The horse takes care of its babies like God takes care of us." Yes, God nurtures us as a mare weans its newborn foal. Job wrote that God's "pails are full of milk" (Job 21:24).Scotty, 6, likes cheetahs: "God created cheetahs because they are fast. God is everywhere, and He is fast."The next time you're tempted to pull a fast one on someone, think of God as a cheetah. You may think you're slick and fast, but at 70 miles...

"It is a bone-deep change you are going into, my beloved," counsels Grandmother Growth. "You must open to your very marrow for this transformation. No cell is to remain untouched. You are to open more than you ever dreamed you could open, more than you have opened in birth or in passion. You open now to the breath of mortality as it plays the bone flute of your being. What can you do but dance to the haunting melody, develop a passion for an elegant posture and a long stride?"Ah, ye s," Grandmother Growth smiles rather wantonly. "It would do you well to develop a taste for dark greens tarted with vinegar and mated with garlic. These things will build strong flexible bones to support you as you...

Do you believe in angels?Of course you do. We all have them. We just have troubles finding them. Sometimes, when we are in big trouble, they find us. Then we're blessed.There are a lot of angel episodes. The one I like best is the story of an elderly couple that got caught in a snowstorm. They could hardly see where to drive. Their car ran off the road and got stuck in a snowbank. They could not get out. The temperature was dropping, and they had little food to keep them alive.They prayed.And prayed some more.Out of nowhere came a truck. They saw his lights, big and bright. The truck stopped and three guys got out, dressed only in tee shirts and slacks. They said they would help them...

The word Website appears first in the title of this article because, especially in the home based business and network marketing industries, you will often be dealing with an individual Webpage or Website as opposed to a large company. That Website might be the independent representative page of a representative, or it could be an independently developed page operated by an entrepreneur.Even if you are looking at a Webpage that is owned by a company, often you will have to go no further in the evaluation process to rule out a particular Website or opportunity. Then, only if the Website passes your tests, do you go on to evaluate the company and opportunity.Please realize, also, that...

Ever get caught without a light meter? Stuck on an important photoghrapic expedition without a way of determining your exposure settings? Well I have, and it worked out ok, thanks to the Sunny 16 Rule and careful consideration of years of experience. Here's the story surrounding this event and how it worked out.High Investment Trip For over 12 months I'd planned and prepared for this wilderness landscape photography trip to outback South Australia. I'd driven about a third of the way across the continent to get to my home base at Roxby Downs, a mining town in the arid desert. I'd driven on pastoral station roads for 82 km to Bosworth Station Homestead where I left the car and trailer. I'd ridden on...

Socrates once said, "The unexamined life is not worth living." Yet sometimes it seems that Americans are obsessed with self-examination and constant change. Individuals once spent an entire lifetime with a single employer, but most people today evaluate their career and lifelong goals every few years. It's common to leapfrog from opportunity to opportunity and to re-make a professional identity several times over. If you're entering college and are perplexed about your future goals, join the club. Even as graduates enter the workplace, they continue to assess their skills and dreams to find lasting success and happiness. Psychologists, educators, and employers have developed a battery of tests that...

I do quite a bit of work online. This is why I demand a great system and a reliable cable modem service. Each and every computer user knows what I mean about the importance of reliability.

Microsoft is revamping its certification tracks, and will eventually retire the familiar MCSE certificatons. The new certification setup is much like Cisco's, where there are specialist certifications to go along with the more general CCNA, then mid-level certifications such as the CCNP, and then a more-advanced practical exam modeled somewhat after the coveted CCIE certification.Microsoft's new specialist exams are the Microsoft Certified Technology Specialist (MCTS) exams. As of March 2006, there were five separate MCTS Tracks. Three of them deal with .NET Framework 2.0; these are the Web Application, Windows Applications, and Distributed Applications certifications. Each of these separate...

Unfortunately, most MLM companies' network marketing training programs consist of barely motivational meetings on conference calls. Most mlm companies fail to teach their distributors the basics of marketing and communications skills. This is considered one of the major reasons for the high rate of failure in multi-level marketing programs.Most network marketers quit, except for the leaders, who start looking for additional training and education. Hungry for success, members of the latter group end up easy prey for the current network marketing training scams.To generate leads, these training programs sometimes use cold calling, but for the most part they use Internet marketing through pay-per-click...
