snap-in failed to initialize

solution:

Applications like Administrative Tools and Computer Management use Snap-ins to control things like disk defragmenting, mmc. So all you need to do is to register these components.

For disk defragmenting:

To do this, open a command prompt. At the prompt, type regsvr32 dfrgsnap.dll
and hit Enter. You will see a window pop-up indicating success of the registration.

Now type regsvr32 dfrgui.dll and hit Enter. You will receive another similar pop-up window. Click OK.


For MMC:

type regsvr32 adsiedit.dll
