Thanks for the info Gav. I've used runh.exe and cmdow.exe plenty of times in the past but have decided not to any more as they give too many false positives to antivirus software seeing them as exploits, and I end up spending too much time proving to security administrators that it's safe to exclude them. I have had a private acknowledgement of its problem, so I hope it will be addressed sooner rather than later. Cheers, Jeremy.

Removing it from the AppSetup value fixes the issue. This article explains the issue on older versions of XenApp, but I wouldn't have expected this to be an issue with Windows 2008 R2 and XenApp 6: http://support.citrix.com/article/CTX108901 Cheers, Jeremy. ________________________________ Confidentiality and Privilege Notice This document is intended solely for the named addressee.
