TCP port 143 is designated for usage with Internet Message Access Protocol (IMAP), hopefully that is your intent.

With that said, make sure that Windows Firewall on both the server and the desktop allow for traffic over port 143. Info on how to do so can be found here - http://windows.microsoft.com/en-us/windows/open-port-windows-firewall#1TC=windows-7

To test that you can connect to port 143, use telnet to connect from the Windows 7 machine to the 2008 server. If the telnet connection succeeds, then connectivity is working.

1. Open a command prompt on Windows 7 desktop
2. In the command prompt type: telnet Windows2008ServerName 143
3. Hit enter
4. If you are prompted for a username and password, connectivity is working

Open in new window

NOTE: You may need to add the telnet feature to Windows if it isn't installed.

If telnet client is not installed, you can use putty - http://www.chiark.greenend.org.uk/~sgtatham/putty/
and then change the connection options as per my screenshot

So is connecting via ssh proof that port 143 is working?
Or must I install telnet?

Is telnet required?
