If you have the patch that Sony released in December, 2002 (one year ago), then the 4.4 server will work for you. If not, don't use it.
Use one of the 5.x versions (it's actually 0.5.x, but who's counting?). Set up a 5.1 or 5.2 if you can get one. This is a somewhat bad time to be configuring a new server. New binaries and source will be released relatively soon to do major bugfixes.
What you will need to do when you configure --->
Follow the standard guide. Do not patch with the big patch in the coming weeks. Make sure you have the most up-to-date itemsdump, available from the packetcollected items links on the
main site. Also make sure you have an up-to-date world database. The world database MUST be said to work with your version. If it's 5.2 on a 5.1, it may not work. This will be hard, because they tend to come out after releases.
I don't know what advice to give you now because I don't see your 5.1 or 5.0 or 5.2 output, and refuse to troubleshoot 4.4. It's very obsolete.
