Constant Disconnection

[IAxxsummerstarsxx]

I can load EQemu with no problem. Everything works, I get into the server screen, and everything is fine. I can load up characters A-O.K. Once I zone in, I get disconnected after about 10-20 seconds I've tried just about every single server out there, and I haven't been able to stay on longer than 30 seconds. I would like to know if there is a way to fix this, or if this is based on my computer/the servers. Can anyone help?

System Specs:
AMD Duron Processor
256MB Ram
Windows ME
I can run normal everquest perfectly fine, but something disconnects me everytime I zone in. Please help.

Thanks
