In the latest version of the recast RCT, the option NOT to use the FQN doesn’t work correct.
5.5.2404.1007-133572465635026811.msi
When NOT checking the setting Use FQN instead of name, RCT actions like Ping work and only use Name, but all the other actions, like connecting to C$, remote management, powershell, etc fail because still the FQDN is used and not only name
