You might want to make sure that you have your Exchange set up to use a forwarding server (usually your ISP's dns server) and that you have the internal nic set to the internal dns server on your network. This plagued me for weeks until I got the forwarding set correctly. I think there's a tutorial on the exchange list website, but I'm not sure where exactly. Hope this helps. -- Ian Sterling MCP, A+, Mac Lover Macs for real work, Windows for the mortgage.
