How do I ‘run as’ ‘Network Service’?

Use PsExec.exe from SysInternals, running from an elevated command prompt.

e.g. this will open a new command prompt running as NETWORK SERVICE:

psexec -i -u "nt authority\network service" cmd.exe 

this will run it as LOCAL SYSTEM:

psexec -i -s cmd.exe 

You can verify these by running whoami from the cmd prompt.
