I've got Windows 2000 Advanced Server installed here but can't find IIS (World Wide Web Publishing Service) in services. Are you sure that it's installed by default? I'll try to search for more information later when I've got some free time.
It's a little bit complicated as there are currently three different "channels" of UURollup - stable
(detailed information available in #1
releases are for testing purpose only so don't use them if having a stable system is a priority for you. Weekly
releases can be installed over previous stable
releases but don't install them over dailies
. If you decide to install a daily
release and then want to install a weekly
release again then the best way would be to uninstall
one before doing that.
In one word, the safest way is to just uninstall the previous version but if it's impossible then you can safely install any weekly
release over older weekly
releases. If you want to be super safe then just stick to stable releases only.
I can't guarantee what will happen if you install releases from different channels over a daily
release since I don't test it
As for Java, you don't need to use any unofficial installers if you've got UURollup installed. Just use the newest official Java 6 installer from here
