Issues with Citrix XenDesktop / PvD and Symantec Endpoint Protection 12.1

Hi all,

we use Citrix XenDesktop (5.6 currently) with Machine Creation services (MCS) to deploy pooled Win7 desktops with Personal vDisk (PvD) 7.0.1.

In the master VM we install Symantec Endpoint Protection (SEP 12.1), and - like many others - we are having issues with

a) the SEP installation becoming corrupted whenever PvD is used

b) Desktops not registering and PvD not functional

I found sources stating that there were known incompatibilites between PvD and SEP, and that it was eventually fixed with an update of SEP and/or an update of PvD. But I cannot find an official (or at least very clear) statement about what exact version of SEP and what exact version of PvD are together fully functional and supported. Anyone?

Thanks

Andreas
