It's hard to piece together what exactly you've tried from this email,  
so please forgive me if you've already done the things below.

Okay, so you're debugging from the point of view of the squid proxy.

On that server, what address(es) are in the resolv.conf file?  Is it  
just the serveriron?

Testing against the address(es) in your resolv.conf, what happens if  
you use dig to try and do the same lookups?  That should give you an  
idea where to start looking.

% dig IN ANY training.in-tend.co.uk @<nameserver address>

Assuming the address above is the serveriron, does your network  
configuration allow you to go around it and try to do lookups against  
the 3 name servers directly?  Use the dig statement above.  If that  
succeeds for all three then you know the problem is with the  
serveriron config, and you should talk to Foundry.  If it fails for  
any, then it's likely a problem with your named.conf, and you'll need  
to debug that.

Hope this helps a bit..
