How to create multiple network profiles on Windows XP/2000.

– Command Line without using any software.
– No additional software required
– Easy to run and manage
– Unlimited number of profiles

Sometimes you need special configs for networks that don’t have a DHCP server running. The problem with those special configs is that they just waste time when you need to go back to the office or your home network. Nothing works and it takes you a few minutes to remember you hosed your network settings to connect to some obscure network somewhere.

Steps to create network profiles on Windows XP/2000.

1. First, save your network profile with all you need (ip, subnet, gateway, dns, wins…)
2. Now you can open a DOS shell with start -> run; then type cmd
3. On shell write: netsh -c interface dump > c:/windows/system32/nethomesettings.txt
the path is optional, you save this as you want, and also the name of file (nethomenetwork.txt) can be different.
4. Now you can setup a different netrwok, like the first profile, and repeat the point 3.
5. On you Desktop, in a free area, click on right button of mouse and choose new -> link
6. write: %windir%\system32\netsh.exe -f c:\windows\system32\nethomesettings.txt
7. Next write the name of link that appear as title of icon, eg: home
8. Repeat the step 6 and 7 for other network, change the name of txt in step six… )
9. you are ready, if you want, you can change the two new icons on desktop, with right button, properties, change icon (the default icon file is c:/windows/system32/shell32.dll).

During a recent visit to an optician, one of my friends was told of an exercise for the eyes by a specialist doctor that he termed as 20-20-20.” It is apt for all of us, who spend long hours at our desks, looking at the computer screen.

I Thought I’d share it with you. 20-20-20

Step I :-

After every 20 minutes of looking into the computer screen, turn your head and try to look at any object placed at least 20 feet away. This changes the focal length of your eyes, a must-do for the tired eyes.

Step II :-

Try and blink your eyes for 20 times in succession, to moisten them.

Step III :-

Time permitting of course, one should walk 20 paces after every 20 minutes of sitting in one particular posture. Helps blood circulation for the entire body.


Tips on Filling Fuel in Your Vehicles
This is a Message received from a friend whoes in Durban:-

“I don’t know what you guys are paying for petrol… But here In Durban, we are also paying higher, up to 47.35 per litre.
But my line of work is in petroleum for about 31 years now, So here are some tricks to get more of your money’s worth for every litre.
Here at the Marian Hill Pipeline, where I work in Durban, we deliver about 4 million litres in a 24-hour period thru the pipeline. One day is diesel; the next day is jet fuel, and petrol, LRP and Unleaded. We have 34-storage tanks here with a total capacity of 16,800,000 litres. ”

ONLY BUY OR FILL UP YOUR VEHICLES IN THE EARLY MORNING WHEN THE GROUND TEMPERATURE IS STILL COLD. Remember that all service stations have their storage tanks buried below ground. The colder the ground, the denser the fuel, when it gets warmer petrol expands, so buying in the afternoon or in the evening…. Your litre is not exactly a litre.

In the petroleum business, the specific gravity and the temperature of the petrol, diesel and jet fuel, ethanol and other petroleum products play an important role. A 1degree rise in temperature is a big deal for this business.
But the service stations do not have temperature compensation at the pumps.

WHEN YOU’RE FILLING UP, DO NOT SQUEEZE THE TRIGGER OF THE NOZZLE TO A FAST MODE.
If you look, you will see that the trigger has three (3) stages: low, middle, and high. In slow mode, you should be pumping on low speed, thereby minimizing the vapours that are created, while you are pumping. All hoses at the pump have a vapour return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapour. Those vapours are being sucked up and back into the underground storage tank so you’re getting less worth for your money.

ONE OF THE MOST IMPORTANT TIPS IS TO FILL UP WHEN YOUR TANK IS HALF FULL.
The reason for this is, the more fuel you have in your tank, the less air occupying its empty space. Petrol evaporates faster than you can
Imagine. Petroleum storage tanks have an internal floating roof. This roof serves as zero clearance between the petrol and the atmosphere, so it minimizes the evaporation.

Unlike service stations, here where I work, every truck that we load is temperature compensated, so that every litre is actually the exact amount.

ANOTHER REMINDER, IF THERE IS A FUEL TRUCK PUMPING INTO THE STORAGE TANKS, WHEN YOU STOP TO BUY, DO NOT FILL UP – most likely the petrol/diesel is being stirred up as the fuel is being delivered, and you might pick up some of the dirt that normally settles on the bottom.

Hope, this will help you get the maximum value for your money.
