Large amount of files keep escaping the layer
Hi everyone, we already have more than 100 virtual apps in our environment. We successfully use this technique since more than one and a half years. However, since the change of the clients (new hardware and sp2 to sp3 from WinXP) we do have some problems with our virtual apps. One of those is that a large amount of files keep escaping the layer. Even on layers with no exclude. The problem is that changing layers (i.e. a newer app version) do not take effekt because almost all of the older files are still in the base. So our Helpdesk needs to deactivate the new layer, clean the file system, reset and activate the new layer and then things are fine. But what's the reason behind this behaviour? We're still on SVS 2.1.3071 because we've had issues with SWV 6.x during internal test phase on German XP.
Could it be a problem because SVS gets installed and then the machine is imaged? So everyone gets the 'same svs installation'?
Thanks for any hints in advance.

I recently had this issue. I
I recently had this issue. I know the post is over a month old but like to add my two cents just incase someone is looking for an answer.
My large amount of files were escaping the layer because I would install/extract and auto activate layers after sysprep and before group policy. File permissions in group policy would apply to the activated layers and all the files would escape the layer. I solved this issue by upgrading to 6.1 and enabled "keep -file -a *" to keep all changed files in the layer that permissions were applied. I had to add exlusions for the files i didn't want to keep in the layer.

Anti-virus programs and othe
Anti-virus programs and othe security software are frequently the cause of this problem. If you haven't already try adding such processes to SVS's Process Ignore List.
If a forum post solves your problem please flag is as the solution
mmmhhh
Good to know that others are seeing the issue as well. Thanks anyone for the posts.
As far as Anti-Virus goes, we're using the latest Symantec Endpoint Protection. Hopefully, this product wont conflict with the Virtualization Solution of the same vendor :) And I excluded already a few of it's executables. However, it's not always easy to determine which executables need to be excluded.
The post above reminds me of what we're doing. We install SVS (2.1) and import a few layers on a client before the machine gets sysprep'ed. And after imaging and deploying the machine, we've got some Group Policies that get applied. Probably someone at Symantec could examine this constellation?
Thanks for any further input.
Files escaped after setting file system rights through GPO!
Thank you so much Rob for guiding me to the right direction. It's exactly like you described it. Since we were setting file system permissions through GPO (i.e. on Program Files folder) those files kept escaping the layer. On clients without this GPO, SVS works fine! Hopefully, this helps someone else, too.
So guys, be careful with file system permissions in GPO and SVS! :-)
