Fixing Destination host unreachable Error
If
the computers is telling you "desintation host unreachable" this means you
have a problem with your physical setup. Make sure all wires are plugged in correctly;
check the power on your hub/witch/router, etc.
Remember, most network adaptors will have one or more
status LEDs that shine out the back of the computer. They should show a green
light if connected properly. Check these too.
If one of your
computers has an address other than 169.254.xxx.xxx, and is
not connected to a router or cable modem, first double check that you
set all the network adaptors on that computer to 'obtain an IP address
automatically'.
If this is the case, go to the command
prompt and type 'ipconfig /release' then 'ipconfig /renew' (for XP and 2000) or
'ipconfig /release_all' then 'ipconfig /renew_all' (for 98/ME). This will
instruct all network adapters to drop their current IP addresses and attempt to
acquire new ones. Type 'ipconfig /all' again and see if this resolved the
problem.
As a last resort, you can
manually set the IP addresses of your network adaptors in order to connect. Go
to the properties of 'network neighborhood' or 'my network places' as before,
but instead of specifying 'obtain an IP address automatically' select 'use the
following IP address' and enter in '192.168.0.2-254 as the IP address, and
'255.255.255.0' as the subnet mask. This will put your computers in the
192.168.0 network. Now test the connection with the ping command again.
Hopefully, this article has
enabled you to successfully connect your home computers together, and has introduced you
to some of the basic networking principles.
The next step is
sharing your Internet connection throughout your home!
