We have 2003 2 node clusters running plant production and shipping applications that have SQL server running on 1 node and the apps with GUI interfaces on the other node. They are configured so that if either node has a failure the failing node apps or database will switch to the other node. We are attempting to upgrade our apps to 2012 cluster, but we cannot get our apps to show on the owner node's desktop. These apps (.exe programs) must display status (i.e. Hand Held scanner status) and allow some user input such as pause, restart, etc. Is there any way around this issue without writing a lot of new code. We currently have 5 such clusters in our plants. Please reconsider allowing applications to interact with the desktop on new clusters.
