    I have a tonne of music and movies bought from iTunes. All stored on my drobo streaming from my mini htpc.

    I want to load sl server on the mini but I don't want to have to authorise my computer as I have already five computers authorised and it would mean having to wipe them all and start again. I also have a number of accounts.

    Does an os change require a new authorisation?

    Thanks

    You will likely need to reauthorize, which may or may not cause you to go over your limit, as it is typically based on the MAC address(es) of the system. You are better off deauthorizing before installing SL Server, just to be on the safe side. The reauthorizing when you are back up and running.

    Does changing the os change the Mac address?

    It's MAC address, they're all capitalized. It stands for Media Access Control address, it's firmwired into your network card. IE, your airport and ethernet ports. Those typically change only if you change your network card, for most people it's something they'll never have to do.

    If you want to upgrade to SL server and this computer is already authorized in iTunes, go ahead and unauthorize it, just for ease. After you either upgrade or reinstall, reauthorize it again. You should have no problem just doing the install, but doing the extra step might save you problems. But I've done reinstalls before without doing that, and have had no problems.

    One cool thing with MAC addresses is, if you are using a router with WiFi you can turn on MAC access restrictions and limit the equipment accessing your node to only certain machines. This is pretty much the most secure you can keep a network, only certain preauthorized devices can actually access the network. It's a pain to set up, because it adds another step in allowing new clients, but only those clients will ever have access.

    Going much further with this concept, some routers will only allow certain MAC clients access at certain times. Example a childs laptop will be restricted to particular times of the day.

    as for iTunes- a new OS install does definitely make your computer ineligible to play DRM stuff.

    Did a fresh install of SL server and my computer is not recognised by iTunes.
