We use Roaming Profiles and something odd just happened on my laptop. We currently redirect My Documents on all desktop PCs to the user's home directory so the files don't copy up and down whenever they logon and logoff. On laptops, however, I enabled the local policy to "Only allow local user profiles" so the documents I save on my laptop would remain on my laptop. Out of the blue yesterday, I noticed that the laptop took a long time to login and the hard drive was thrashing like mad. When it finally came up, I discovered that all of my local files moved from my local My Documents folder to the My Documents in my home directory and the local My Documents was now redirected to the server. I checked and that policy setting was still enabled on my laptop.
Any idea on what would make this happen suddenly and the best way to undo it?
