We are running Linux on 56 Solaris servers.

All but two of the servers are working fine. They are all cloaned.

On two servers we cannot ping the default gateway:

# ping 192.168.32.3
PING 192.168.32.3 (192.168.32.3) 56(84) bytes of data.
From 192.168.32.127 icmp_seq=0 Destination Host Unreachable
From 192.168.32.127 icmp_seq=1 Destination Host Unreachable
From 192.168.32.127 icmp_seq=2 Destination Host Unreachable
From 192.168.32.127 icmp_seq=3 Destination Host Unreachable
From 192.168.32.12# ssh 192.168.32.3

Attempts to SSH result in:

ssh: connect to host 192.168.32.3 port 22: No route to host7 icmp_seq=4 Destination Host Unreachable

My next step is to compare all of the files under /etc with those of a good server. Any help? Thanks!

Divide and conquer:
Can you boot off another operating system and see if they are working fine hardware wise? Are they getting DHCP served addresses - maybe the pool is full? Can you re-clone to see if it is a configuration issue?
Good luck
