1. I understand OS(but server edition???) Would use Win XP...
well, crosslight, winxp as your OS is not enough if you intend to setup your own media server. (though it works apparently according to pgp_protector, but dont know coz i havent tried it with xp) you require a server operating system either windows 2000 professional server, win2003 server, or linux.
okay... you're on broadband... now, find out if your ISP provides you an unlimitted bandwidth for both inbound and outbound. there are ISP's who has limitted bandwidth for inbound & limitted bandwidth for outbound. there are some ISP's as well who provides unlimitted bandwidth both inbound & outbound like my current ISP.
IP address is the address your computer is allocated by your ISP everytime you connect to the internet. STATIC IP Address is if everytime you connect to the internet, the IP address of your pc remains as is, where as Dynamic IP Address is that everytime you connect to the internet, your pc is allocated different IP address (not permanent unlike static which is permanent). again, most ISP's doesnt provide static ip's (due to marketting issues most probably), but, there are some ISP's who provide static ip's for their custumers like my current isp.
to help you find out if your IP is either static or dynamic is by trying this step first: start - run - type ipconfig ( you'll see your current IP address). now, logoff then reconnect to your internet.. repeat the process: start - run - type ipconfig . if the IP address is similar to your first attempt, then, you have a static ip address.. however, if it is otherwise, yours is dynamic. (hope you're grasping what i mean). post back if your IP is static or dynamic.. if static, you wont have any problem setting up the media server later on.. if dynamic, it is still possible but require extra works.
we'll do it one at a time then... but first, you need to find out with your isp your bandwidth consumption ... if it's limitted or unlimitted... and find out as well if your IP is either static or dynamic...
