here is a link where you can d/l ultima online: http://www.gamespot.com/promos/ultimaonline/index.html
this is the actual client needed to play ultima online. make sure to patch the client. dont register the game, u wont need to.

next make sure to d/l uo razor, a free shard tool that makes logging and playing uo easier. for those who used uoassist before, its just like it. d/l link here: http://www.runuo.com/razor/
make sure you have Microsoft's .NET Framework installed before you try to install uo razor.

once everything has been installed and patched, run uo razor. once the razor screen has poped up, go to where it says "server", select "uogamers: hybrid(uor), and then hit connect. now all you have to do is enter a username and password and thats it. welcome to the best free ultima online server.

if anyone needs any assistance with it, you can message me at aim: chicohimself or icq: 15069227
ill try to answer all questions you have abut the game.
