computer name mapped to a wrong IP address

[Guest]

I have two w2k computers networked via Vigor2600X ASDL router
Both computers have TCP/IP as well as NetBEUI.
Both have TCP/IP properties set to obtain an IP adress and DNS server
address automatically.

When I ping computer2 from computer1 using
PING computer2
everything goes well

When I ping computer1 from computer2 using
PING computer2
I have 100% loss

It also shows
Pinging computer1 [192.168.0.1]

However running ipconfig on computer1 returns a different address:
192.168.1.11

Correspondently, if I ping computer1 from computer2 using 192.168.1.11
instead of computer name it works fine.

It looks like the computer name is mapped to a wrong IP address - how can I
sort this out?

Check your hosts & lmhosts files to make sure the incorrect address is not
listed there....

Check the entry for that system in your DNS server, and also in any
hosts file on computer 2.

Thanks,
On computer2 I got the wrong address 192.168.0.1 mapped to computer1 in
HOST
What am I supposed to do about it:
a. Enter the correct address
b. delete the whole line?

On computer1 I have only one line
127.0.0.1 localhost
and yet it pings computer2 without ptroblems.
Does this mean that mapping IP addresses to computer names the HOST file is
optional and if HOST is empty, the mapping is taken from some other sources?

"Check the entry for that system in your DNS server" - how dop I do this?

The entry in the hosts file should not be necessary....if you remove it, and
restart your computer, what happens?
