Here's the setup:
Dell Server running Windows Small Business Server 2003 with Exchange
Clients using Outlook 2003
SpeedStream 5200 DSL Modem/Router
Exchange is set up with an SMTP virtual server that was delivering all our external mail to the world with out incident. Our original SpeedStream 5667 DSL Modem/Router failed and was replaced with the 5200. All my outbound mail is stuck in the SMTP queue. If I highlight one one of the entries in the queue it reports "Remote server did not respond to connection attempt" From a command prompt on the server I have tried "telnet <smtp server name> 25" and I get "Connect fails". This works from computers outside the office. What would my next troubleshooting step or is there an easy fix. I'm assigning high point value because I need to get this going by Monday.
