We are migrating to a new network AND upgrading from 10.2.200.40 to 10.2.700.21. The new network is VERY locked down. I’m getting an error when trying to run an EXE from within a customization using Process.Start, which works fine in our current environment but not in our test environment. I’ve attached the error I’m getting. Would anyone have experienced this before, and would it be related to a specific port or port range now being open? Any help would be greatly appreciated!
