I have just got the contract to install sbs 2003 at a customer who currently use a ASP and wishes to have everything in-house. Currently there are 9 client machines running xp. In regard to cal and microsoft office licenses, I constantly hear it is cheaper to use the open license programme , but this seems expensive in regard to buying 5 cals and 9 oem copies of office. Have I missed something here? Is it legal just to buy oem copies and install them? If anyone has got any suggestions, please help!
