Your net mask is almost certainly wrong.  No one has a class B on an
ethernet segment anymore!  My guess is you can't see the name servers
because your VMS system is trying to send directly to them and it
needs to go through your router.

Can you ping the router (137.222.187.250) by address?  If not,
your LAN might be subnetted to smaller than a /24 and you should
have a local router to get to the rest of it.  But most likely,
your netmask should be 255.255.255.0 (/24).  Ask your network
people...
