ip works dns doesn't

I have just set up an nt 4 box with IIS on our school lan. Here is the
db. file from our unix system:

> cat db.vrjc.cc.tx.us
;
; Forward resolution for local names
;
; This file is machine generated by the configdns program.  You should
; use that program to make changes if you want to continue using it
; in the future.  If you make changes here, they will be lost the

Inside my firewall i can't reach the library.vrjc with the name or
with the ip address.  Outside (from home) I can reach it with the ip
address, but not with the name.  If I set the ip address to
206.254.36.16 Then I can get to the library.vrjc server from inside or
from home but only with the IP address.  

When I run nslookup I get:

> nslookup library.vrjc.cc.tx.us
Server:  chaps.vrjc.cc.tx.us
Address:  0.0.0.0
 
Name:    library.vrjc.cc.tx.us
Address:  206.254.36.34
 
> nslookup 206.254.36.34
Server:  chaps.vrjc.cc.tx.us
Address:  0.0.0.0
 
Name:    library.vrjc.cc.tx.us.36.254.206.IN-ADDR.ARPA
Address:  206.254.36.34

any help would be appreciated.
