Now that we’ve prepared our image for this change we have to make sure that the definition files are present on the persistent disks on all VM’s in the environment. The notification icon can be a bit behind.
#Symantec endpoint protection update definition download how to
So here’s a Step-By-Step instruction on how to accomplish this. That was easy enough. Even after a reboot I now have up to date definition files and I have an extra GB of data on my system disk where the files used to be. I stopped the SEP client, copied the entire Definitions folder to a location on my persistent disk, made my registry changes and started the client. There are a number of values that need to be changed but I’ll get to that later. The path to this folder is located in the HKLM registry. You can tell by the little arrow symbol on the folder: The CurrentVersion folder is actually a symbolic link to the folder named after the SEP version (in this case. If the files are out of date, updates will be downloaded to the corresponding subfolders. After the SEP service starts the client checks the current files, which are located in this folder: C:\ProgramData\Symantec\Symantec Endpoint Protection\CurrentVersion\Data\Definitions. Here’s how I did it: The solutionįirst I figured out how the update process works within the SEP client. So I decided to create my own redirection solution. The problem is that the SEP client does not have a configuration option that will allow you to do that. The obvious solution to this unwanted behavior is to move the definition files to a location on the persistent disk attached to the VM. This means that, each day since the last vDisk version, the client will have to re-download all definition files after every reboot.
Since a non-persistent desktop loses all updates after a reboot the Symantec Endpoint Protection (SEP) clients’ virus definitions also resets to the moment you last updated the definition files in your image. Citrix PVS is used to stream a read-only vDisk to VM’s on a XenServer infrastructure.
I’m currently working in a Citrix XenDesktop environment with pooled, non-persistent desktops.
