Computer Training Excuses - No ExcuseYou wouldn't go to a doctor who had never been to medical school, or hire a lawyer who never studied law. One side-effect of a world advancing as rapidly as ours is that fields are becoming more and more specialized and narrow. People can no longer get by on general knowledge in their careers, something I found out for myself not too long ago. I'd been out of high school for two years, scraping by on my own and picking up scraps of programming as I went. I saw all of the self-taught programmers breaking into the IT industry, and I hoped to do the same. After all, IT is one of the few industries out there where being creative and a quick learner is more important than a degree.

PowerShell: Windows Command Line on Speed - PowerShellWho needs another shell? Unlike the Unix world, Windows hasbeen pretty consistent with the shell environment. First there was MS-DOS (COMMAND.COM) and later Windows NT (CMD.EXE). You can actually still get to COMMAND.COM if you really, really want to. But for all intents and purposes, these have been the only two shells Windows users have ever known.

Microsoft wants to change that. When .Net was announced in 2000, Microsoft promised everything would one day be .Net. Unfortunately, Microsoft stuck the .Net name on things that were not .Net at all, such as Passport.Net which had no managed code in it at all.

What is Windows NT?

A version of the Windows operating system. Windows NT (New Technology) is a 32-bit operating system that supports preemptive multitasking. There are actually two versions of Windows NT: Windows NT Server, designed to act as a server in networks, and Windows NT Workstation for stand-alone or client workstations.


Tips

Changing Process Priority

Is a program or process running too slowly, or is one hogging all of the CPU time? Go into the task manager and click on the "Processes" tab. Right click on one of the processes and change the priority class to one of your choosing. Give mission-critical processes high priority and lower those of non-essential tasks.

Larger CPU Usage Graph

If you want to see your CPU usage graph in a larger window than that normally allowed by NT 4.0's Task Manager, just click on the Task Manager's "Performance" tab and double-click the window. A larger graph of the CPU performance will appear in place of the "Task Manager" window temporarily.

Missing a Command Prompt Shortcut?

For various reasons, a shortcut to the command prompt may be missing from your Start menu. If you need to get to it fast, just click the start button, choose "R"un, and then type COMMAND and press ENTER

System Sluggish? Check your Services

If your NT system is running a little sluggish, you may want to check and see if you have unneeded services running.

Click on the "Start" button, choosing "Settings," and then "Control Panel." Double-click the "Services" icon, and look at the list of services.

From the "Services" menu, you have many options including shutting down services temporarily or forcing them outright to never start up again. It is recommended, when attempting to disable services that you are unsure about it, to only temporarily disable such services at first and examine how NT reacts. Then, force the service to run manually instead of automatically, and if all goes well after a testing period, outright disable such service.

Can't Find the Mouse

There may be times when installing Win NT 4.0 that it can not detect the mouse. Even worse, the mouse service can not be started - period. According to the Microsoft Knowledge Base, this is normal with the release of NT 4.0 and can occur when performing an upgrade or under certain other conditions. If this happens, you may want to install the latest Service Pack which should fix the problem.

This error did occur on a test machine, and installing the service pack fixed the problem - just thought I would let you know. Getting *to* the download area wasn't fun without a mouse, though :(

Take Care with your Screensaver Choice

If you like to use screensavers, carefully decide which screensaver you wish to use on a server computer. Some of the fancier screensavers, such as the OpenGL screensavers, use a high percentage of CPU time, slowing down your running services. Stick with simple screensavers or use none at all for servers.

Did You Know?

  • Windows NT was thought to be a very big break through for servers because now they used GUI. Although, many linux used GUI as well but this was Micro$oft.

  • An Indian discovered that in MS Operating Systems, nobody can create a folder anywhere named as "con". Not only con but you cannot create folders named as "aux" nor "nul". This is something pretty cool...and unbelievable... At Microsoft, the whole Team, including Bill Gates, couldn't answer why this happened! Try it out yourself...
