Stand alone DNS server on 2003 not working, Am I nuts or is it buggy

I have a very simple setup:

At home I have a PC with Windows 2003 srvr install, DNS and Symantec AV for SMTP installed.  The purpose is if my main network goes down, mail can spool at home and just send when the main netwokr comes up (HINT - This stops TONS of spam, as most spams try mail servers in reverse order).

I have the server at home static IP 192.168.199.3
I have a D-Link router on the cable connection with ports 53 and 25 mapped to 192.168.199.3

I have 3 public DNS servers at the office (1 stealth (on firewall), 2 visable (ns1. and ns2. both on 2003)  I have my home IP registed as ns3.

Mail works 100%, but all of a sudden my home PC stopped getting dns updates from the stealth server.

I've try all the following:

1. set ns3 to get update from ns1 and ns2 (with ns1&ns2 told to all transfer from ns3)
2. on Ns3 I can load nslookup and do a full LS of the doamin from the stealth server, and ns1
3. Reinstall 2003, only added DNS, added the domain back (std secondary) with all 3 other dns servers set as my source
4. check event viewer for any errors, NONE

This should be plain simple (was the first time I set it up).  I've seen before where the other DNS server refuse the transfer, but that gets listed in the event log.

Any ideas on what I can do / try?  or a 3rd party free dns server I could use?

thanks

Your Stealth Server is running what OS?  and, are you running ISA 2004 on that server as your firewall?

My Firewall is an SEF V9.0 firewall - That is working fine as the other 2 2003 DNS server seem to be able to get the info.

I almost wonder if it is something to do with my d-link router.  But like I said, I can do an NSLOOKUP to the firewall IP, and the other name server.

If it was running fine up until some point, then there must have been a change to it somehow.  Is the router on the border or the firewall?

If the router is not between the firewall and the other DNS servers then I can't imagine it is interfering with things.

Could you explain this statement a little more clearly? "...but all of a sudden my home PC stopped getting dns updates from the stealth server"  -  I'm not sure exactly what you are trying to say.

Cheers.

The DNS server ran fine for a good year, but then I had an update to make to the www entry.  I noticed (after much ado) that ns3 did not get the update for the www entry.  I tried to force it - no change. since then I have not be able to get the home dns server to update.

I'm going to try upgrading and wiping the dlink box and set it up from scratch if that somehow is blocking.  

but if the requests are being blocked or rejected, the DNS server should log that.  I'm sure it's something small, but the DNS server should have better logging.

How are the zones configured?  Are they Primary/Secondary or AD Integrated?

The main server is non Windows, so it's just a primary,

all the other servers are Secondary.

Ok, so I assume you have rechecked the secondaries to make sure they are still accepting zone transfers from the Primary?  Also, is the Primary inside or outside the D-Link?

Not sure you know, so excuse the next statement - Secondaries can't be updated directly, they must receive a transfer from the Primary - I assume you know that though.

One thing to check, since your Primary is not a Windows DNS server you must disable fast zone transfers - simply check the option for Bind Secondaries in the Advanced server properties of DNS.

I upgraded the D-link to new firmware and everything started to work (after re-installed my config to the dlink).  The DNS updated in seconds. ( Now my IPSEC pass through does not work)


Lessions:

1. Dlink - not so good for this use.
2. Win 2003 DNS error logging is lacking (should have loged that no response was received)
