I'm using D10D clients to connect to a xenapp 6.5 farm. I'm using pnagent and the connection works fine, however, right after logon, the wyse client comes up with an error message "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond".
However, the connection to xenapp farm is not broken, so when you press OK to the error message, it switches back to the desktop/xenapp and you can work as normal. So the solution works fine, no connections gets dropped, but we get a lot of calls from our users because of this error message and would like to fix the problem.
I do not get similar errors with S10 or C10 clients to the same farm. My wnos looks like this: (removed servernames and domainnames, and farmname)
