when i try to start a dedicated server he says : unable to open: ms32.dll not found...

anybody can help ?

You need to run the server on a game installation... not just with the server files that you download from here.

what ? you thik i must run the game first ? ( i do everyting in the tut (but perhaps its because my iw4m flooder is not in my mw2 flooder ) i can play the game whitout problems so idk ...)

You need to run the server from the same folder as mss32.dll is, wich is the game folder.

ok thanks
