DNS Resolve Problem

[Paula.Deal at MitchellRepair.com]

I am running Bind 4.9.7 on an NT 4.0 server, SP4.

I have had no real problems resolving addresses until last week.
I have one specific domain name that will not resolve, which is
MCIWORLD.COM
When I use nslookup, I get DNS request time outs.
When I set debug, my domain name is appended to MCIWORLD.COM.

I can not see any problems with my resolve.conf file.
I have the following 2 entries:
	domain	mitchellrepair.com
	nameserver	207.212.82.35

Any help would be appreciated
