We have a pretty static XenDesktop/XenApp farm (two farms actually - separate and distinct from one another) and all of a sudden, we have a small number of users getting SSL Error 4 errors when connecting to either XenApp or XenDesktop.
By connecting, I mean it lets the user log in, but when they try to launch an app or a desktop, they get the SSL Error 4. Specifically, the error is:
Unable to launch your application. Cannot connect to the Citrix XenApp server. SSL Error 4: the operation completed successfully.
Now, these two farms are static. NO changes in the netscaler or the controllers or the certs. We are pretty darn sure it's machine specific because these users who are impacted can move to other machines and connect just fine. Also, these two farms have hundreds of users and only a small number are reporting the problem.
Can someone point me in the direction of what might be going on here?
