iTNo is running as a console application without any problems, but when running as a service errors are reported.
The account you use to start the service doesn't have enough rights to use RAS or the Internet or the Proxy.
Start the service with Administrator or the account you use to logon onto Windows NT and then it should work.
You have Windows 2000/2003 and when running iTNo as a console application the last screen line is not visible.
By default the Windows 2000/2003 screen buffer size height for a console application is set to 300 lines.
Select the Properties of the console and then select the tab labeled Layout and change the Screen Buffer Size Height to 25
The logfile shows
Error: Unable to start inbound HTTP connection manager
Error: Port or address already in use 
iTNo can't bind to port 80 because there is already an IIS running on this port.
iTNo runs on the IIS machine:
You haven't bound IIS to a different port like port 81.
See the documentation, section Running iTNo on the same machine as Exchange server, how to bind Exchange to a different port.
iTNo runs on a different machine:
Most likely there is another Web Server running.
