It seems that the disk fragmentor component for mmc in your saved item is corrupt. I assume you are running Windows XP.
I suggest to perform the following: Click on START and then RUN, type in MMC and then click OK.

The MMC Console will now start up.

From within the MMC console ... click on FILE and then ADD/REMOVE CONSOLE

In the STANDALONE tab towards the bootkm of the screen ... select ADD
Disk Defragmentor should now appear
Select Disk Defragmentor and then select ADD After the above is complete. Select CLOSE Then select OK

Disk Defragmentor mmc console is now opened.
I suggest to save this to your desktop or anywhere else by selecting FILE and then SAVE/AS
Give it a file name and then click OK

Your disk defragmentot should now be up and running.
Good Luck. :-)

File names of common Windows applications


Windows operating systems have many useful programs that come built-in and ready to go. These programs can typically be accessed by navigating through the Start menu or opening the Control Panel (or by typing their names in the Search bar if you have Vista). But sometimes you may want to pin the program to your Start menu or create a shortcut on your desktop, so that you can access it quicker and not have to hunt it down every time you want to run it. In order to do that, you'll need to know the program's file name and where to find it (unless you're running Vista, in which case you can use the instant search feature).

Below are some common Windows programs and their respective file names. Each of these files can be found in the \Windows\System32 folder. (The locations may vary on a 64-bit system.)

Command Prompt = cmd.exe
Computer Management = compmgmt.msc
Device Manager = devmgmt.msc
Disk Defragmenter = dfrg.msc
Disk Management = diskmgmt.msc
Services = services.msc
Task Manager = taskmgr.exe

Another useful file to be able to find is the explorer.exe file. Sometimes when the system locks up or a program freezes, your taskbar and/or desktop shortcuts will disappear. Rather than reboot the computer, you can run the explorer.exe file and "refresh" the Windows desktop. The explorer.exe file is located in the \Windows folder.

You can find these files by opening My Computer, selecting the C: drive, and then going to the Windows folder and then the System32 folder (unless you're looking for explorer.exe). Once you've located the file you want, you can right click on it and select either "Pin to Start menu" or "Create shortcut" to make it easier to access in the future.

My computer has lost the file to defrag, can you fix this? E-Machine, 2004, Windows XP, ITUV.92, 280GHZ, 80GB,512MB,W4885


Are you sure you lost the file or simply the shortcut icon?

To be sure, click Start>Run. When the window opens, type dfrg.msc in the Open box and then click OK.

What does that do? If that starts your defrag program we simply need to create a new shortcut for you.

Comment back.

Cannot Open DSA.MSC file error


When you install the Administration Tools Pack on a computer that is running Windows XP Professional x64 Edition, the Active Directory Users and Computers MMC snap-in file (Dsa.msc) is installed in the %windir%\Syswow64 folder. Additionally, the computer's file system maps the Active Directory Users and Computers MMC snap-in to the following path: DriveLetter:\%windir%\Syswow64\Dsa.mscHowever, the Active Directory Domains and Trust MMC snap-in incorrectly specifies the path of the Active Directory Users and Computers MMC snap-in as follows: DriveLetter:\%windir%\System32\Dsa.mscWhen the computer's file system tries to locate the Dsa.msc file from within the Active Directory Domains and Trust MMC snap-in, Mmc.exe is run. Mmc.exe is run because the Dsa.msc file is associated with Mmc.exe. When Mmc.exe is run, it uses the following path to locate Dsa.msc: DriveLetter:\%windir%\System32\Dsa.msc DomainPathAfter the Mmc.exe command is run, the Active Directory Domains and Trust MMC snap-in tries to locate the Dsa.msc file. Because the Dsa.msc file does not exist in the %windir%\System32 folder, the error message that is mentioned in the "Symptoms" section is generated.

To resolve this problem, manually copy the Dsa.msc file from the %windir%\Syswow64 folder to the %windir%\System32 folder.

Your hardware manufacturer provides technical support and assistance for Microsoft Windows x64 editions. Your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.

For product information about Microsoft Windows XP Professional x64 Edition, visit the following Microsoft Web site:

Cannot Open DSA.MSC file error


In my case, the file was already there, and had been working for a long time prior. Making a copy of the file, and calling it something else (dsa2.msc), then pointing my shortcut to that, corrected the issue. Why? I have no idea. This same thing has just happened on a second device also -- surprised there are not more posts about this situation out there.

Defragment does not work


You need to re-register the defragmenters snap-in files, and the basic registry entries.
  • First open up a Command Prompt, this can be found at:
    Start -> All Programs -> Accessories -> Command Prompt

  • Change into your windows\system32 directory. Your windows directory will be either windows or winnt. Type:
    cd \windows\system32

  • Register the defrag components, by typing:
    regsvr32 dfrgsnap.dll
    regsvr32 dfrgui.dll


    registerdefrag.gif

  • At this stage, you may find the defragmenter works. If not, there is one more step you can do.

    Using Windows Explorer browse to your windows\inf folder.
    In there you will find a file called dfrg.inf right click this file, and select Install.
  • If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
    Thanks, Joe

Defragment does not work


Hi,

This problem can be tacked in a few ways. But I cannot guarantee that it can solve the problem. So please do try out all the alternatives shown below one at a time.

  • Go to Start and then Run, type regsvr32 msxml3.dll and run it, or
  • Start --> Run, regsvr32 dfrgsnap.dll and start - Run, regsvr32 dfrgui.dll and then click on OK, or
  • Go to Start - Run and then type sfc /scannow. (If it asks for the installation CD, insert it) or
  • Install the latest MMC 3.0 (Available at Microsoft site) or
  • Browse to C:\Windows\Inf (Assuming C drive is your OS drive), right click dfrg.inf file and click on Install.
If the above does not solve your problem still, then try renaming the dfrg.msc file to something else and place the shortcut in your start menu.

If everything fails, it can only be a registry or a .MSC association problem...
