Hi Tim,
Yes, I have the SD card installed. After reading this thread I'm thinking that may be the issue.
My Arduino Ethernet Shield is attached to an Arduino Uno R3 smd, and I'm using IDE 1.0.1. I haven't had time to test anything on it tonight, hopefully I'll get to it tomorrow.
It works fine with DHCP, but last time I tried to set a Static IP I was unsuccessful.
