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.
But when I tried to look at it from a Win2K machine with nslookup:
Default Server: ns1.abd.com
DNS request timed out.
timeout was 2 seconds.
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.
