You simply add it to the target line of the M:TW shortcut:

Code:
"C:\Program Files\Total War\Medieval - Total War\Medieval_TW.exe" -strictserver
So it looks like this:

Code:
"C:\Program Files\Total War\Medieval - Total War\Medieval_TW.exe" -strictserver -ian
(Don't forget to use the shortcut: if you start the game via the auto-run menu it won't work.)
