Connectivity Test
Option 1 - Ping Test
With the HOSTS file or DNS configuration
in place (see connectivity) you should be
able to ping the server by its NetBIOS name. Click
Start, Run, type CMD and press Enter to launch a command
prompt window. Type the following at the prompt
PING MAIL
and press Enter. You should receive 4
replies. If you receive no replies or an error message
about an unknown host, usually the cause is a file
extension on the HOSTS file name (see connectivity).
In most cases you should not waste your
time trying to set up Outlook unless and until you can
successfully ping the server. However, if you're behind
a firewall, many firewalls prevent ping traffic. If that
is the case, you will not be able to ping anything. To
verify this situation, try to ping
www.yahoo.com. If you can't ping Yahoo, you
probably have a firewall in the way, or another network
problem.
If you have installed the hosts file
intended for use with VPN, remember you will not be able
to get replies to your pings unless the VPN is
connected.
Option 2 - Browser Test
There is another test you can use if a
firewall interferes with your ability to ping. Pull up a
browser window and try to go to the Internet address:
http://Mail
If you have successfully configured
NetBIOS name resolution, you will see the Junctionbox homepage.
If not, you will see an error message. |
