unable to get a nslookup on windows client

[Agnello George]

HI
I am trying to test my DNS ( bind- dlz ) server ( 192.168.03.244)   from a
remote windows client ( 192.168.0.209 ) . I have a domain  called sample.com
. The hostname of my r DNS server  is testserver.com .
When i do a nslookup on the server for sample.com it returns me the
following :
[root at bind ~]# nslookup sample.com
Server:         127.0.0.1
Address:        127.0.0.1#53

Name:   sample.com
Address: 192.168.0.244

when i do a nslookup for 192.168.0.244 i get the following on my DNS server

[root at bind ~]# nslookup 192.168.0.244
Server:         127.0.0.1
Address:        127.0.0.1#53

244.0.168.192.in-addr.arpa      name = ns1.testserver.com.

but wheni try to do a nslookup for 192.168.0.244 on my windows client i get
the following i can how ever ping to 192.168.0.244

C:\Documents and Settings\Admin>nslookup ns1.testserver.com
*** Can't find server name for address 192.168.0.244: No response from
server
*** Default servers are not available
Server:  UnKnown
Address:  192.168.0.244

*** UnKnown can't find ns1.testserver.com: No response from server

On my DNS server using the command "elinks" i can view the webpage for
sample.com hosted on another remote machine.

I have disable iptables a did a setenforce to 0 , but still get the same
above resulth on a remote windows client.
Where exactly am i goiing wrong ?

Thanks for al the help
