It usually happens when you have installed some 3rd party tools related to defragment and then uninstall them.
Have you uninstalled any softwares like Ultra Defragmenter, Mydefrag,Defraggler, Diskeeper or Speedefrag.
It is also possible that you have removed them long time ago and do not remember.
The solution is simple.
You need to re-register the defragmenters snap-in files and also some basic registry entries.
These 2 are the main dll's for it.
In Windows Explorer go to your windowsinf folder.
Locate a file called dfrg.infright click this file and select Install
There is actually no problem whether or not you use third-party disk defragmenter applications on your computer. The Windows Disk Defragmenter included in Microsoft Windows should operate normally. Now, if you have a third-party disk defragmenter application installed on your computer, try running that disk defragmenter and see if you can defragment your hard drive. If you can then the problem is with the Windows Disk Defragmenter app.
If this is the case, you probably have damaged system files on your computer. To fix this, click Start, Run, type without quotes “cmd” then hit Enter. In the command prompt, type without quotes “sfc /scannow” then hit Enter. When you are prompted, insert your Windows XP setup CD on your CD/DVD drive and then continue. This will repair any damaged system files.
Once it is finished, try running Windows Disk Defragmenter again and see if you can now use it to defragment your hard drive.
