DNS (BIND) setup problem?

I tried to configure the BIND in Fedora core 1. It seems to work fine with Linux machine with nslookup:

[root@localhost root]# nslookup
Note:  nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead.  Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
> scada.net
Server:          66.100.135.166
Address:        66.100.135.166#53

Name:   scada.net
Address: 135.200.1.67

But when I tried to look at it from a Win2K machine with nslookup:

C:> nslookup
Default Server: ns1.abd.com
Address: 66.100.135.166

> scada.net
Server: ns1.abd.com
Address: 66.100.135.166

DNS request timed out.
       timeout was 2 seconds.
Name: scada.net
Address:  135.200.1.67

And the problems:

1) SMTP and POP3 servers quite often have problem identifying scada.net. Mail client will time out.
2) IE quite often cannot identify the site scada.net.

Please help.

Below is the output from a dig on my web server.  First thing is to dump nslookup for troubleshooing.  Dig gives you all the info you need.  

It looks like scada.net is at a new IP address.  I would recommend restarting bind/named and nscd to flush cache.

The timeout from the XP box is pretty standard on the first resolution.  Just saying hey it took a couple secons to resole the address.

Here is the output from the dig.

bash-2.03$ dig scada.net

; <<>> DiG 9.2.1 <<>> scada.net
