This file is wrong. You also need:
search domain.com
Your "dig @solaris solaris" command showed that you are not resolving correctly. Dig did not return an answer.
Just to confirm, my /etc/resolv.conf looks like this
# generated by NetworkManager, do not edit!
# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
#
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# SEARCH=lab.foo.com bar.foo.com
domain domain.com
nameserver 192.168.X.X
