How To Repair / Install Recovery Console / NTLDR In Startup Windows Server 2003

Easy Procedure For Installing Recovery Console On Windows XP/2003/2000 As NTLDR Startup Option

Note: I have tested if this helps us install recovery console in windows 7, if any reader tries it out, please let me know how the process goes.

If you have been using Windows 2000, Windows Server 2003 or Windows XP, you must be aware of the Recovery Console (RC) feature that is present in all these operating systems. This console helps the user recover the system if it fails to boot by making use of a limited array of tasks that can be executed through command line interface.

You may invoke the Recovery Console with the help of the installation CD-ROM. You normally need to boot up using the CD and repair Windows XP/2003/2000 system using this Recovery Console.

If you are unable to boot up using the CD or you aren’t willing to alter any boot device priority settings in BIOS, you may as well get the recovery console installed into your local hard disk. By doing this, you can select recovery console option from the boot-time menu that is offered by NTLDR.

It is impossible to install the RC on an updated Windows system using old version of Winnt32.exe present on the setup CDs. Hence, you need to install the Console into the local hard disk prior to installing any kind of service pack.

If you try installing Recovery Console with the old CD on Windows having integrated service pack, the system shows an error message notifying you that the set up is unable to continue as the version on CD is older than the Windows version running on your computer.

To prevent such an issue, it is advisable to install the RC as soon as the installation of Windows is over. You need to follow the below mentioned procedure to get Recovery Console installed as a NTLDR startup option.

First of all, logon to Windows XP, Windows Server 2003 or Windows 2000 with administrator rights. You have to note that network policy settings might not allow you to complete the procedure incase your system is linked to a network.

Once you logon to Windows XP/2003/2000, place the Windows XP/2003/2000 CD in the CD-ROM drive. You will see a prompt asking you whether you wish to upgrade Windows. Just select “No” or else close the window.

Go to Start Menu and select “RUN”. Type the command mentioned below. As another option, you may use command prompt to type the command.

x:\i386\winnt32.exe /cmdcons

You need to replace “x” in the command with drive letter of DVD-ROM or CD-ROM so that it finds the proper Winnt32.exe file present on the CD. Further, just follow the instructions given on the screen to complete the procedure.

Now that you have installed Recovery Console into the boot menu, it is possible to select it to run each time you start the computer. You no more need to boot using a CD.

How Do Reset Or Upgrade DRM Utility in Windows Media Player

Errors due to Digital Rights Management (DRM)  constraints in Windows Media Player (WMP) – be it in Vista, Windows XP/ 2000 / 9x / Me – can be quite annoying. This happens particularly if the media file is copyrighted and thus frequently shows DRM license errors. The only solution to this problem is to change the copyright (i.e. DRM) settings of Windows Media Player so that it does not show error messages.

Moreover, there is another problem that can crop up while using the FairUse4WM (FU4WM) – a handy application that removes the DRM component of the copyrighted media that you purchased – and you might get an error message saying:

<filename> does not appear to be licensed to you

This error arises primarily because Mirakagi tool gets started before the license is actually acquired by FU4WM. A simple suggestion is to wait till the Play button is activated before you press the Start button in Mirakagi. However, if you have not installed the copyrighted media’s license key properly, then this error will keep on cropping up and you will have no other option than to reset the DRM license settings manually.

Also, you should know that resetting the DRM settings in WMP is equivalent to re-individualizing WMP. This means that all the media DRM licenses will be cleared and the DRM settings will be reset to a clean original state – the idea being that all errors are undone in the process. In this case, if you want to play the media file again, you will have to go to the site you bought it from, and buy a new DRM license that is valid.

You should read this informative guide to WMP DRM settings if you want to know more about this issue.

Requirements to get most out of the Speach feature in Office XP:

One of the most exciting features for me on Office XP is voice dictation and voice-activated commands. If your computer is outfitted with a speakers, sound card and a microphone (you can also manage with an earphone headset), you can dictate information into your Microsoft applications, such as word and excel. You can also make use of this feature to activate the menu system in most Microsoft Applications.

Requirements to get most out of the Speach feature in Office XP:

To make the Speech feature useful, you will need a fairly high-quality microphone. Microsoft suggests a microphone/headset combination. The speech feature also requires a more powerful computer than the other Office XP applications typically need. Whereas Office XP needs only 32MB of RAM (memory) on a computer using Windows 98/Me (64 MB of Windows 2000).

According to Microsoft a Pentium 2+ with 128 MB RAM is ideal, but with computers going cheap day by day, one can go for Intel Core duo with 1 GB RAM, which is optimum according to me, as a computer exceeding the normal standards get the best out of the Speech feature.
