When using the XenDesktop Setup Wizard, have you ever encounter a problem with the Setup Wizard not allowing you to choose an existing desktop group, even though you already have created a group in the DDC?
One of the possible reason why it does not show your desktop group could be because of the address you keyed in for the hosting infrastructure does not match the address of the desktop group. To verify, open your Delivery Services Console on your DDC and view the properties of your desktop group. Select “Logon Information” and check the “Address” property.
Make sure that the “Address” you key in on the Setup Wizard matches this. If it does, then the desktop group should appear for selection when using the Wizard.
