When I test via telnet 127.0.0.1 25 from the sever it looks as if it conencts and I get a - then the tenet ends and I am back to the c prompt.

Have you tried disabling firewall, antivirus, malware scanners, etc on the server to make sure that the problem is strictly related to Exchange?

its happening inside. I am going a reinstall of exchange 2003 sp1 and sp2.  After sp1 I check and smtp still does a quick disconnect.

That sounds like classic Anti-Virus interference.  What have you got installed on your server?

Please run the following from a command prompt and upload c:\netstat.txt for review:

netstat -anbp tcp >c:\netstat.txt

Can you telnet the internal  IP address of the server on port 25 and not the Loopback (127.0.0.1)  address please.

Disable windows firewall or stop the service, then try the telnet again from the server itself and from another machine on your network.

Check the application event log for errors / warnings when you try the telnet. You may have IP address restrictions in place on the SMTP virtual server.

So rather than keep the question going and respond to our comments, you paid Microsoft!  Interesting!!
