Spells get no LoS

[DeanTodd]

Hello,
Just recently, I got a Minilogin EQEmu server set up just for fun of some friends and I.
Everything works smoothly; I'm on a hardwired LAN (all of the computers in question are plugged into a 5 port hub) and the hosting server is a small Sony laptop. Duo core, Windows XP, 2gb ram, and so on.
The server starts up well; on the client computers, it works great, but there's one major problem.
No matter what location I'm in, offensive spells can never get a line of sight.

Throughout everything I've tried, every nuke, debuff, dot, etc.. I get an error "You cannot see your target" or whatever it says when that happens.

As far as I know, I can. I can be standing right next to the NPC and still not see it.
Anyone have any ideas as to what might be causing this?
Is it a database value that isn't correct? (Database is PEQ by the way)
Thanks!
