Cannot connect to the Citrix XenApp Server

This error “Cannot connect to the Citrix XenApp Server” happen from time to time, this is a message from the XenApp plugin (ICA Client). Today I had this one because we have move some servers and they had to change their IP address. The IT server team told me everything was done I should be able to put this machine back in production, all changes have been done and everything is working well.

BUT, when I enable these servers, this windows appear for all the users who try to launch a publish application :

snap00270

This message means the Citrix XenApp server cannot be reach with the address return by the datacollector. So i have assume the server team did the change on the network configuration of the servers but didn’t reboot it…

To be fast, I make the choice to just restart the IMA service, it did the trick.
