We're having an issue with the "%appdata%\Microsoft\SystemCertificates\My" folder not clearing down on logoff for certain users and even the domain administrator cannot get access to or take ownership of this folder. This means that when a user next logs on to a published desktop, an additional profile folder is created, which prevents pinned items from working & probably other things too. We use Flex Profiles, so I'm not sure if this is to blame. Any help gratefully received! Cheers. Nik
