SUMMARY
=======

This article describes the PortPing utility that is located in the Microsoft
BackOffice Resource Kit.

MORE INFORMATION
================

You can use PortPing to verify that a computer is actively listening on a
specific port. For example, you can use PortPing to verify that your server is
listening on port 25 when you install an Internet Mail Connector on your
Exchange Server computer, and then start the Internet Mail Service. When you use
PortPing, you can type either the host name of the server or the Internet
protocol (IP) address in the Target Server box. If you type the host name and
PortPing fails, type the IP address. If you can reach the specified port when
you type the IP address, but not when you type the host name, the name
resolution service on the computer may not be working properly. When you run
PortPing, if the remote port is listening, you receive the following message:

  Success! Pinged port x in y milliseconds.

However, if the remote port is not open or if a firewall is blocking that
particular port, you receive the following error message:

  Error Detected: Connection refused <XXXXX> returned.

In this error message, <XXXXX> represents the error code.

PortPing, click the article number below to view the article in the Microsoft

The following scenario describes how to use this information for troubleshooting
purposes:

  Messages are backed up between two Exchange Server computers that are
  connected by an X.400 connector. The X.400 connector uses Transmission
  Control Protocol (TCP) port 102. To confirm that this issue is caused by
  network problems, run PortPing to that port number. When you start PortPing
  to make a remote call on the server to port 102, if the ping command does not
  come back successfully to port 102, you can confirm that X.400 mail traffic
  is not flowing.
