Then we discovered that this behavior only occurs when an app stack is attached. Only disabling "Application & Device Control" seems to improve login and application performance.īy accident we found out that SEP didn't work at all !! Everything looked fine from SEPM and SEP side.The SEP GUI indicated that there were no problems detected "Your computer is protected", but stopping and then starting the smc.exe resulted in a crash. It may seem that the service is running, but in reality the Symantec client has crashed see image below. The only way to start the SEP client was rebooting. We also saw that a simple EICAR test virus was not detected even when the SEP client was running and the GUI indicating that the computer was protected. We`ve been testing all scenario`s disabling components of SEP. When SEP is installed including all obvious exceptions and even using the virtual image exception tool no significant change in performance is noticed. Without a SEP client installed everything is performing well and user experience feels like a persistent VDI. App Volumes and Symantec Endpoint Protection 14.x doesn`t seem to like each other. We`ve been troubleshooting slow login and poor application performance on our Non Persistent VDI for a while now.
