I mistakenly turned on IE ESC for users on one of our 2008R2 servers that is running XenApp 6.5. When the mistake was realized, I turned it back off through the server manager for both Admins and Users, but users are still getting prompted with the blocked content messages. Even though it's off for users, it's not really.
Normally, this happening to just one server wouldn't be a huge deal, but this server happens to be source for a vdisk image that we're using to provision to a number of client servers through XenApp Provisioning Servers, so it's really affecting eight of them.
We've done some research and it appears correcting this faux pas has been a pain point for terminal servers for years and there is no clear, easy way to turn off the button that was turned on... that we can see anyway. Any solutions that don't involve deploying registry edits through Group Policy or resetting Internet Explorer settings for users one by one? My favorite suggestion to-date came from this KB article (even though it applies to 2003): http://support.microsoft.com/kb/933991
... option #1 says "it may be quicker to rebuild the terminal server". Geez, I hope not.
Your suggestions are appreciated. Thanks!!
