Defragmenter not defragmenting?

Do the “analyse” and “defragment” buttons not do anything in your Windows XP Disk Defragmenter? You probably need to make sure the “DCOM Server Process Launcher” service is running. I had mine turned off. Apparently this is a bad thing to do — it would appear that it is no longer enough for defragmentation to run as a normal program; it needs to be a DCOM process connected somehow to some service. Way to Microsoft it! Also, you don’t seem to be able to start that service normally, the only way I could make it work was to set it to “Automatic” (it was on “Manual”) and reboot.
