Hi everyone. this is my first post so if I'm doing something wrong please go easy on me. My question is as follows I've purchased a Fujitsu Primergy server and a 'Fujitsu ROK - Small Business Server Standard 2011 With 5 CAL - English' (part no S26361-F2567-L350). The server has arrived but the software has not (and is unlikely to turn up till after Christmas) . Can I install SBS 2011 from an ISO I've downloaded from the web (labeled 'en_install_disc_windows_small_business_server_2011_standard_x64_dvd_611535.iso') and then activate with the key from the ROK pack at a later date (within 30 days) and if so do I need to do anything special?
