I think I finally got everything working, but when I finally got one of the OSX desktops connecting, the server started saying "event "somethingsomething" could not be saved to the server(it may be too large)" After about an hour and a half of clicking "save" I thought all was well but now the client on the XP machine says "error : server problem -39"

Now a large number of events that were previously in another category have been moved into a category called "unreconciled events" and I'm not sure why it happened or what to do with them.
