Hi , Quick one 2003 R2 XenApp5 should I have DEP enabled or not. Jut I am having some issues with an EAccess Violation on a custom written app from a vendor and they can't seem to get to the bottom of it. I see a lot of posts relating to DEP for this error. Problem is it is very intermittent, and even when it happens to a user if I connect to the same server I can run the app. If turning off DEP isn't an issue, this may be the way to go. I have read that its best practice in 2008 R2 with XenApp6.5 but haven't found anything on previous version.
