RAC Installation (Valid IP Error)

Question

Hello Guys,
I am installing 2 nodes RAC 10g R2 on windows XP platform.
Each node contains 2 network cards for private, public and virtual IPs.
Following is the seeting of TCP/IP on each node.
Node 1
Netwrok Card 1
Public IP : 192.168.0.140
Virtual IP : 192.168.0.141
Entry of these IPs exist in DNS
Network Card 2
Private IP : 10.0.0.1 - Entry exist in host file with the computer name
Node 2
Netwrok Card 1
Public IP : 192.168.0.142
Virtual IP : 192.168.0.143
Entry of these IPs exist in DNS
Network Card 2
Private IP : 10.0.0.2 - - Entry exist in host file with the computer name
Now during installtion where we have to configure IPs of node its says:
"The following Public IP do not resolve to a valid hostname. Enter Valid IP that maps hostname to continue"
How to rectify this error to continue....
Please Help.

Node 1
# Copyright (c) 1993-1999 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
10.0.0.2     bss-training71
bss-training71.beaconhouse.edu.pk is the public name of this node
192.168.0.142 is public IP Registerted in DNS
192.168.0.143 is Virtual IP Registerted in DNS
