Not sure of the best forum to put this in, so sorry if it's in the wrong place...

I have nearly all my Windows XP users in a policy package being pushed out by Zen 6.5 (sp1, I believe). In that policy package, I have enabled roaming profiles. Now, I'd like to simply turn that off. What will be the ramifications of turning off roaming profiles in that policy package? What are the "gotchya's"?
