Can connect to other DR4 servers, but not mine

[sianyde]

I've compiled the 5/29/04 DR4 release from biosprite. World and boot5zones start fine, with no item errors, etc. I can see my server at the server selection screen. When I try to connect to it, the screen goes black (like it normally does), then I hear HD activity (like it normally does), but after about 3 seconds, I end up back at login. I don't get a 1017 error (if I do, I don't see it). I can log in to other people's DR4 servers. I don't know if anyone else can log into my server. I've searched for this error, but the closest thing I've seen to my situation is when people crash out to desktop, or get stuck at character creation, and I'm not having either of those problems (right now at least).
