Going from XenApp 6.5 to XenDesktop 7.8, I made the transition from using ICA connections to the Storefront presentation for our thin client users. The problem was the Storefront sessions were timing out. Our XenApp thin clients use hardcoded passwords based on Wyse variables, so the users do not know them. Sure, a restart would log them in again, but there must be a more user friendly option.
These thin clients ship with few Trusted Root Certificate Authorities. You may find, as I did, that the provider of your SSL certificate is not one of them. Even if it is as recognizable as DigiCert. So now you need to add it.
