Currently I am building a new XenApp 5.0 farm that requires both Windows 2003 and Windows 2008 servers. As a part of this process I am publishing applications and testing them as I go.
The old Presentation Server 4 environment is obviously all Windows Server 2003.
Publishing Explorer for users is not a new issue for Citrix server environments. The correct way to do this is to not publish explorer.exe at all but instead publish Internet Explorer in explorer mode.
