Well I am getting a bit long in the tooth (Solaris 7) but it sounds like you
might have an error in /etc/nsswitch.conf

Do you have a line which says:

hosts: files dns ....etc?

If this is the case, the system should check the hosts file for name
resolution first. If the "files" bit is missing, it won't check it.
