I am trying to get Windows XP's defrag working. I know the answer is simple, and I know the answer is out there. I got it working at one time, by using a tip that was stored on the 911cd.net forums. As we all know, the 911cd.net forums are no longer working. I have the MMC working, and the Defrag console comes up nicely. When I click on the Analyze or Defragment buttons, I get the message Disk Defragmenter could not start. I get the same message on the command line version. The answer to getting BOTH working is the same, I just CAN'T remember what it is, and it is bugging me. Anyone? Any ideas? Please??!!
