confguring etchosts with different machines having same na..

Hai,

I am trying to setup a PC to collect data from two different networks
(class addressing of both are the same - 192.168.1.xxx).

There's a problem I am facing now:
Network1 is analogues to Network2 in terms of PC names. The networks
have PCs (UNIX based) with same names but different IP addresses.

For example:

In network1,
I have PC1 with IP address 192.168.1.1

In network2,
I have PC1 with IPaddress 192.168.1.101

Now I need to connect this third PC (windows based) into the network
to read data from the two PCs above. How do I configure the \etc\hosts
file with these PC names and addresses. There would be a clear
conflict or rather the machine mentioned first in the hosts file will
only be accessed. Is there some work around to this?

Thanks in advance.
