although that does read well it still runs a startup script to begin the install on the workstation and i would find that the office install because it is so big can have problems espically if you try to install this along side other programs like flash, shockwave, adobe reader i just always find the likes of office to install this either manually or in an image instead of over the network.
also remember that with sever 2008 and windows 7 that anytime you run command you need to right click and run as Administrator even if you are logged in as an Admin its still not a full Administrator account always remember to right click cmd and run as administrator
