had a similar problem (not in workplace) last month when trying to mount an NFS 
exported directory from one linux machine (say exporter) on another linux 
machine (say mounter). mounting used to fail with same message "No route to 
host" . We checked the routing table - it was fine.  mounter could mount 
exported directories from other machines though.
I don't remember it now, perhaps ping or some other utility we tried then used 
to give 'unreachability' messages for exporter.
finally we tried tcpdump on mounter and found that some transactions were 
happening b/w exporter and mounter. they couldn't have happened if there was 
problem with routing/dns etc.
on further investigation we found the source of problem - the mounter had a 
linux distro (from one of the computer magazine CDs) installed and had some 
default application running with default settings. if i remember it correctly, 
it was iptables. we updated the default configuration to one for the setup and 
things worked fine.

above experience might help you. examine the settings at your linux end 
(server). tcpdumping at linux end will help you
