Shovel, the only message I see on the server console is where you connect, verify guid and disconnect. Usually the players gets more info on the disconnect message. Can you get into other servers? Have you tired verifying cache files through steam? If not, pull up your steam library and right click on the arma2, aramaOA and dayz mod files to get menu and click on properties then click on the verify files tab. If you delete local content, you will have to re-download the entire game so dont do that if you can help it.
Once verified, the game is supposed to replace corrupt files on the next attempt at connection. It may disconnect you from the game to download the needed files. Maybe this is whats happening and it just needs some download time with the game open to make things right. Also a slower connection bugs the ftp and has a harder time getting the replacement files.
Just a thought.
