you guys seem to know everything, so I&#039;ll give it a shot:<BR>I keep getting an "error: 2140 internal NT error" when starting the Exchange Internet Mail service. I looked in the event log, and it mentioned something about checking my connections. It all seems good. I have my domain set to route to &#060;inbound&#062;. I have the email address set to my user name. The service just won&#039;t start. Any ideas? I&#039;m using Exchange 5.0 btw. Is there a way to upgrade it to 5.5 for free or do I need to purchase it?<BR>thx<BR>~~Chaotix
