DNS: Can't find server & forwarders not working

Dear fellow linux experts and users,

I have set up my own DNS server for resolving names in my private domain
(192.168.168.xxx). Also I want to use service of the name servers suggested
by my ISP to resolve names on the internet. (I have set up the PPP and it
seems to be working ok.) I tried two things, both unsuccessful.
1. I put the suggested name server address in resolv.conf

Content of my resolv.conf is:

----------------------------------------------------------------------------
--------------------------------------
nameserver 203.17.73.5
nameserver 203.17.73.6
nameserver 127.0.01

----------------------------------------------------------------------------
--------------------------------------

Starting nslookup, it says:

----------------------------------------------------------------------------
--------------------------------------
***Can't find server name for address 203.17.73.5 : Non-existent
host/domain
***Can't find server name for address 203.17.73.6 : Non-existent
host/domain
Default server : local host
Address : 127.0.0.1
>

----------------------------------------------------------------------------
--------------------------------------

However when I queried the name server 203.17.73.5 directly in nslookup, it
works fine. I did this by changing the server in nslookup and then ask it
to resolve sunsite.unc.edu:

----------------------------------------------------------------------------
--------------------------------------
>server 203.17.73.6
Default server : xxxxxxxxxxxxxxx [can't remember the exact response here]
Address : 203.17.73.6
>sunsite.unc.edu
[proper answer then returned from the name server]

----------------------------------------------------------------------------
--------------------------------------

Is there something wrong with the suggested name servers or is it my set up?

2. I added the "forwarders" line to the local name server with the two name
server addresses provided by the ISP.

Since nslookup cannot use the suggest server as default, I tried to use my
local named to forward my request to them. However, nslookup failed to
resolve names like sunsite.unc.edu. It said something like "non-existent
host/domain" (from memory, can't repeat the exact wording).

Again is it that the server failed to perform recursive name resolution or
is it my set up.

Also any suggestion of other ways to achieve my primary objective.

Thanks for any help.

Regards
Andy Siu
