When running the Citrix Group Policy Modeling Wizard from my local PC via Group Policy Management console, receiving error, "Failed to connect to back-end server 'localhost' on port 80 using binding WSHttp. The server may be off-line or may not be running the appropriate service.
It seems that the Wizard just needs to be pointed to the right servers in our XenApp 7.6 environment. I'm not sure where this is done. Citrix Studio is running correctly from this PC but I was able to tell it where to connect.
