Hi I have implemented a test environment for VDI using following videos
http://technet.microsoft.com/en-us/video/microsoft-vdi-part-i-server-side-configuration
http://technet.microsoft.com/en-us/video/microsoft-vdi-part-ii-virtual-desktop-configuration.aspx
http://technet.microsoft.com/en-us/video/microsoft-vdi-part-iii-client-side-experiences
My Setup
1 Server 2008 R2 (RD Virtualization Host)
1 Server 2008 R2 (RD Connection Broker, RD Gateway, RD Session Host, and RD Web Access)
I have 5 Windows 7 VM in Virtual Desktop Pool.
Within https://vdi-01.myschool.com/RDWeb when users click on RemoteApp Programs >> MySchool Desktop/My Desktop icon to logon, it throws following error after entering username and password.
As part of the installation process I have "MYDOMAIN\Domain Users" a member of "Remote Desktop Users" group in the Session Host Server.
You help will be much appreciated, thank you.
