We?re running XPe right now, but we?re upgrading (eventually) to PS4.0. They want this for the current farm, for now, but I don?t think we use isolation environments at all right now. Thanks for the tip, though. --------------------------------- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Jim Kenzig http://ThinHelp.com Sent: Monday, February 06, 2006 2:47 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: CHAX software If you are running CPS 4 you can run it in an application isolation environment. Should work fine as that is what it is designed to do.. give users their own registry. There are other products out by Tricerat and Provision Networks to name a few that let you do this also if you don't use CPS 4.

They [CHAX] claims it won?t work in a Citrix environment because it doesn?t use ini files for each user in the shared environment, it uses registry files that can?t be accessed by more than one person at a time. Any thoughts or suggestions? We?ve got a 50-server XPe farm here, and I was asked to research this software. This is what their technical support came to me with. Thanks.
