Burning DVD in Vista

Windows Vista offers a  feature to burn files and folders. However making a backup of a DVD movie will make some trouble on some DVD players, for instance the default.ini file included in the root folder. When you try to remove this file, Windows Explorer will fail to burn the DVD at all.

Fortunately I found some great freeware tools to backup my DVDs. Folder2ISO, LC ISO Creator, and ImgBurn. First you create an ISO file and the use ImgBurn.

RAM upgrade and virtual memory

 Pimp My WheelchairSince I bought a new computer, each component separately,  the RAM was incompatible with the mainboard. Although changing the RAM settings in BIOS to manual, what made the system stable, was insufficient for my needs. After reviewing the mainboard book, I found the CL3 version of Kingston 1 GB module being compatible and fast. Soon I ordered it on Amazon online store. My Computer’s performance increased in application loading times and visual movements. The only drawback was the bad smell. However, one day later it was fine, the smell decreased entirely. When I saw the improvement, I ordered one more. Now my system works with two Gigabyte of memory.

Although virtual RAM seemed useless, I thought about a technical suggestion I have read on Microsoft’s MSDN site: Set paging file (virtual ram) to a other hard drive than the Windows installation. Most PCs running Windows however contain one hard drive like mine, RAID 1 mirror. Therefore I bought a cheap external case and mounted one of my hard drives inside, which was dusting in my room.

Finally I removed the page file from the Windows drive and set it to the USB external drive. The improvement was immediately noticed. Actually I disabled Welcome Screen and set the machine to login itself. I have seen the loading profiles message with the old settings, but now the LCD screen disappeared, it said that the screen mode was unsupported, and I was required to power off the screen. When I powered the screen on again, I saw my Desktop already. After changing the LCD to use 75 hertz instead of 60, the issue was solved. Now I noticed right after the Windows XP boot screen my Desktop! What an performance improvement!

Enable security options in Windows XP Home

I tried to enable the security options in Windows XP Home Edition, I changed the registry settings “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa”, like on my previous Article and found, it was not working. I was wondering about it, and saw, it is only attend to work on XP Professional, but I was not like to give up!

Finally I found a solution for it by installing “scesp4i.exe”. By the way the file is hosted on the Microsoft ftp server, but when I was trying to download, of course, it was busy! So I used google.com and found a mirror link. I extracted the content to a temporary folder and followed the instructions included in the readme file. After the setup was done, I saw the NTFS permission coming up!

Reserved Words

When you use file systems like “FAT” or “NTFS”, there are restrictions by naming a folder or file. You cannot use specific words to name your data. The restricted words called “reserved words”. One example is: your PC is communicating with your printer on LPT1, the reserved word is: LPT1. To name a folder “LPT1″,”LPT2″,”LPT3″, etc. wouldn’t work, unless you are one PC-freak, knowing how to hack.

There is also some interesting fact about using the space character: folders cannot end with empty spaces, when you try it, it will be ignored and left out.

Using Internet Explorer there is a special bug creating folders or files that usually cannot be deleted. Indeed the file system is messed up by ignoring the rules of naming a folder or file. Such problems are found in the folder next to “C:\Documents and Settings\[your login name]\Local Settings\Temporary Internet Files\Content.IE5\..”. The error: files like something[1]. cannot be deleted.

To solve this issue you are required to have a short Command-Line or DOS knowledge, knowing how to change a folder name or using the commands like CD, DIR and DELETE.

dir /x /a:s browsing the folder where the problem is found.
Note the short names with 8 characters like DOCUME~1 and the long name Documents and Settings

Example:
Long name: C:\Documents and Settings\Manuel\Local Settings\Temporary Internet Files\Content.IE5\FOLDER
Short name: C:\DOCUME~1\MANUEL\LOCAL~1\TEMPOR~1\CONTENT.IE5\FOLDER

You need finally a tool called RM.exe. It is included in the Windows 2000 Resource kit under the apps\posix\ folder but you can find it browsing www.google.com, search for “download RM posix” (without the quote mark).

Copy the RM.exe to the root of your C: drive.
Open the Command Line (CMD.exe) and browse to C:\> by switching with CD\
Following should delete the file:
rm  //C/DOKUME~1/MANUEL~1/LOCAL~1/TEMPOR~1/Content.IE5/FOLDER/something[1].

More Reserved Words:
COM1-COM9, LPT1-LPT9, CON, PRN, AUX, CLOCK$, NUL

Enabling security options in Windows XP

NT based machines have security options for any file and folder, allowing or restricting access to your data. Having  business documents viewed or edited by kids would be embarrassing. Since Windows XP the security field seems gone, fortunately it is disabled and invisible through the user interface.

Enabling or disabling the security interface for any folder and file is simple. One tool is required: “Regedit”. It is located in the Windows system folder, start it by using the start menu->Run. Next, type Regedit and press Enter button.

Step by step guide to enable the security options:

1. Start Menu ->Run
2. Type Regedit, press Enter
3. Find “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa”, it looks like a Folder in Windows Explorer
4. The right side should display a Name “ForceGuest” (type of Dword),  if not add it by using the right mouse
5. Change the value of “ForceGuest” to zero

Reserved Words Exploited

When you haven’t read my previous article “Reserved Words”, use the link below:

Some Server Administrator may already came across and found themselves unable to delete certain files, the file system was exploited and messed up using reserved words or other restrictions. The simplest way to create files or folders not allowed by the operating system is using the FTP Server.

Actually it is impossible to create folders called “LPT1″, but when it happen, Administrators will not even note it, because it will be invisible even on the Command Line. Trying to delete an empty folder might seem strange, when an error appear telling it isn’t empty etc. Then we can assume, there is a reserved word used.

The most worst part however is, knowing the problem but having no idea to solve it. I am talking about seeing folders, but having no chance to delete, it’s the “empty space” bug. When a folder or file has an empty space in the extension on the end, it will not be possible to erase the file like usual. However, downloading the file using FTP will be possible by adding the HTML code %20.

To avoid such issues I am suggesting to disallow renaming files on FTP Servers.
