Hi. I am now having the exact same issue.
I have a fully offline, isolated Horizon test lab.
I am also having the 40-80 second delay in launching ThinApp packages via Horizon Applications.
I read the thread, and am trying to do what cstonimaatta and Linjo have done to compensate. But, I must have it wrong.
When you, Tony, say you "pointed those out to my horizion server server so it replies with http" ...
What exactly did you do? Here's what I did (which isn't working.) Can you please point me in the right direction?
Here is my (fake) verisign.com zone: http://screencast.com/t/Lj03pKZfhL
Here is my (fake) windowsupdate.com zone: http://screencast.com/t/KWx4BcbtWY
From the client, it resolves perfectly.. http://screencast.com/t/l7ztdrsgfPjp
Should I not be pointing these toward the gateway, and instead some other server?
Please advise.. Thanks in advance !!
