Hey gang. Somewhere along the line defrag stopped working. Kept getting some kind of MMC snap-in error. Found some help on the web that suggested re-registering a couple of the dfr*.dlls. When I tried registering dfrgsnap.dll, I kept getting an error stateing it wasn't and executable file. I finally saw where someone suggested expanding it from the I386 directory from the install CD. The odd thing is that the compressed file (dfrgsnap.dl_)wasn't there. Doing a search on the CD I found it under the d:\AMD64 folder. I expanded and registered. Fired up defrag and ran it on a partition that wasn't important. Seemed to work fine. I am guessing it's fixed but wanted to see if anyone had any comments before I defraged my more important partitions. Thanks for you time
