Via the GUI it is easy however…
Recently I had the need to run an application from the command line under a different user context. My computer was not domain joined but I wanted to run the application as a domain user. I achieved it using the line below.
runas /netonly /user:sub.domain.tld\username "C:\Windows\System32\mmc.exe C:\windows\System32\dsa.msc /domain=sub.domain.tld /s"
