Impacket exec family (psexec/smbexec/wmiexec/atexec)

Impacket's psexec, smbexec, wmiexec, and atexec examples provide distinct authenticated methods for remote Windows process execution. They are alternatives, not a sequence: psexec and smbexec use SMB and service control; wmiexec uses WMI/DCOM; atexec uses the Task Scheduler RPC interface. Required privileges, network paths, output transport, and supported authentication options differ by method and release; verify the selected script's permissions and version rather than assuming every method needs the same local-admin and SMB-write combination.
