Are you able to look up names in other domains that those servers host?
For instance, can you look up www.actechnologies.net?

If not, here are two reasons I can think of:

1) There's a communication problem between your server and the network
that ns1.us.dellhost.com and ns2.us.dellhost.com are on.  Can you ping them
from your nameserver?

2) Your server may, somehow, have incorrect addresses for those server
names.  If you look them up, they should be 209.235.107.14 and
209.235.107.16.  If not, you need to check all your files to see where you
may have these names entered.

To troubleshoot further, turn on tracing with "ndc trace", try to look up
www.yorko.com, and then check the trace file to see what it was doing.
