Shadowing in XenApp 6? Not if you have Multi-Monitors.
While working with the newest versions of Windows 2008 R2 and Windows 7, I am beginning to notice more and more compatibility issues with Multi-Monitors and various Citrix products. Changes with the new graphics driver model (WDDM) seem to be wreaking havoc with these types of remote presentation products. With VDI and the move to Windows 7 on the desktop not to mention XenApp 6’s requirement of Windows 2008 R2, implementations might get a lot harder before they gets easier. Chris Hahn stumbled across this on in the Citrix knowledge base.
Shadowing only works in XA6 if there is only a single monitor on both sides. Multi-Monitor shadowing is no longer supported because of OS limitations.
