We have 3 remote users who are using WYSE Thin Client. They are coming in VPN via Comcast to a Citrix Access Gateway. The version that we are using on the CAG is the Standard version with firmware 4.5.8 Build 19. We publish XenApp to the Remote Users and at a certain time it freezes. It freezes about the same time every day but the network connection is still working. I’ve done a ping test to multiple servers when this event occurs. All Citrix Apps that we publish gets frozen. Now the only thing that doesn’t happen is that our internal users at the office do not get affected by this. They all seem to work fine.
