Several times I've noticed that machines will not always look to a secondary
DNS server when the primary goes down. Why is this? |

it's my experience that windows 2000 just isn't very good about this. xp and
server 2003 tend to work just fine. What's your specific set up? "Absolutely" <abs@spam.never> wrote in message news:%232H34jFQGHA.2828@TK2MSFTNGP12.phx.gbl... > Several times I've noticed that machines will not always look to a > secondary DNS server when the primary goes down. Why is this? > |

2 2000 Servers (SP4), one with AD, the other member. DC is primary DNS and
member is secondary. Member is also mail server (IMail) and DHCP. Workstations are 2000 and XP. At some point last week the primary stopped responding to DNS queries (restarting the DNS service cured it), but even though the secondary was running fine, nothing would look to it for answers.

To add to the below - bear in mind that a client will consider a DNS server
alive so long as the server can be contacted (via an ICMP ping). That means, that if the DNS service has hung, clients will *not* revert to the secondary server, since the primary is still available. This is as per RFC 2182 behaviour. hth, neil "Kevin D. Goodknecht Sr. [MVP]" wrote: > Absolutely wrote: > > 2 2000 Servers (SP4), one with AD, the other member.

What is happening is that the primary is hanging and connectivity to it is
lost (perhaps a bad NIC, but haven't determined that yet). If I try to go into the properties of the secondary I just get a warning that it can't load the zone.

Also if attempting nslookup when the hanging on the primary occurs, I get
this from the workstations: DNS request timed out. timeout was 2 seconds. *** Can't find server name for address 192.168.25.20: Timed out *** Can't find server name for address 192.168.25.40: Server failed *** Default servers are not available Default Server: UnKnown The two IPs are the DNS servers.

Didn't try to query, but I don't believe either server would resolve
anything. The way I found out about this is that my mail server was returning messages as undeliverable. When I looked further I found it could not resolve the names of receiving mail servers. Forwarders are set to my circuit provider's DNS servers on both the primary and secondary. The only firewall is between the WAN and LAN. DNS servers and mail server is on the LAN. "Kevin D.

Ok, so how do I determine if the workstations are in fact using the
secondary? And, even if they are, what would be the issue? All I know is that as far as I can tell I have everything configured correctly and if the primary goes down, things stop working. "Kevin D.

Make sure the DNS server is listening on the correct IP address, has a good gateway address in TCP/IP properties, and can contact the forwarder and root servers on port 53 UDP. Post the ipconfig /all from the Alternate DNS server machine and a client. Do this to see if the Alternate DNS can resolve names. nslookup <hit enter> server <AlternateDNSIP> <hit enter> www.microsoft.com <hit enter> You should also try nslookup from the machine that hosts the Alternate DNS against the forwarder and root servers. -- Best regards, Kevin D.

In news:%23V1PLmjWGHA.1084@TK2MSFTNGP04.phx.gbl,
Absolutely <abs@spam.never> typed: Do you think my question is unimportant? Does nslookup resolve any queries after the initial "can't find server name for address 192.168.25.40"? Nslookup reports this message because it is performing a reverse lookup on the DNS server IP address. Also, you have a second IP address that is not on the same subnet, it has no gateway, and as DNS servers often do, that will try to connect to the primary from this second address, which causes zone transfers to fail. You should not have IP address on the same NIC on different subnets. > > DNS server is listening on all addresses, the gateway is good and can > contact the forwarder and root servers.

Wow, it has been over a month since originally asked about nslookup, this thread has been going on for 6+ weeks now, I can you resolve this, but it is like pulling teeth to get information from you. I had to go back and refresh my memory on what's been done and tried, with all due respect, I can't you if you dodge every question. What kind of firewall? Are there any rules on the firewall that would prevent either of the servers from using recursion? Does your ISP's DNS support recursion? Do you have recursion disabled?(Advanced tab) Can you nslookup the ISP's DNS from the DNS server machines? Replace the Root hints file. 249868 - Replacing Root Hints with the Cache.dns File: http://support.microsoft.com/default...roduct=win2000 As for the secondary zones not loading when the primary is down, increase the expire time on the zone, 1 day is generally not enough if you are using a secondary zone, 2 to 4 weeks is the recommendation. Create a reverse lookup zone and PTRs for the DNS server's IPs so it will stop the nslookup message. -- Best regards, Kevin D.

Sorry for the delayed responses. I have very limited time to work on this.
I'll review what you've sent and let you know. Thanks. "Kevin D.
