Ping "replies" from same computer with 'Destination host unreachable' (no route to other computer)
- by Srekel
I've got two computers in a LAN behind a wireless router.
One has XP with ip 192.168.1.2
This one has W7 with ip 192.168.1.7
If I try to ping the other one from this computer, I get this:
C:\Users\Srekel>ping 192.168.1.2
Pinging 192.168.1.2 with 32 bytes of data:
Reply from 192.168.1.7: Destination host unreachable.
Reply from 192.168.1.7: Destination host unreachable.
Reply from 192.168.1.7: Destination host unreachable.
Reply from 192.168.1.7: Destination host unreachable.
Ping statistics for 192.168.1.2:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Tracert gives the same result:
C:\Users\Srekel>tracert 192.168.1.2
Tracing route to 192.168.1.2 over a maximum of 30 hops
1 Kakburken4 [192.168.1.7] reports: Destination host unreachable.
Trace complete.
Although I can ping and tracert the router without any problems. I have disabled the firewalls on both computers. The router is set to use DHCP (if that matters).
Here is the output from "route".

I've set up and debugged a few networks in my life but I'm not really an advanced network user, so I'm not sure what might be wrong. Any ideas? Oh, and pinging this computer from the other computer doesn't work either.
