DNS Server problem - nslookup DNS request timed out

Hi

I had a Win2003 DC, sometimes it don't answer DNS requests, even to it self.
everything else seems to work, I can logon remotely to the server etc.

I then made a new DC, now it has the same problem.

The event logs don't have any related errors.

Perfmon tells me that the servers are doing nothing

Any idear how I can solve this?

Re: DNS Server problem - nslookup DNS request timed out

Hello Andersen DK AndersenDKdiscussions.microsoft.com,

So Hamlet is a client i assume? Why does it have 2 DNS entries, when you
have only one DNS server?

Re: DNS Server problem - nslookup DNS request timed out

Hi Meinolf

Hamlet.dk is the AD domain the 2 Ipconfig's are from the 2 DC + DNS servers,
where I have seen the problem. I do have one more DC where I have not seen
the problem (yet.)

(And yes I know the AD domain has a domain name also used on the internet, I
did not make the AD.)

Re: DNS Server problem - nslookup DNS request timed out

Hello Andersen DK AndersenDKdiscussions.microsoft.com,

So srvdc01 and bernardo are both DC's and DNS server? Do you use AD integrated
zones, if not i would change to it when the DNS servers are all on the DC.

Then change the ip configuration to this:
bernardo
IP Address. . . . . . . . . . . . : 192.168.1.6
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
DNS Servers . . . . . . . . . . . : 192.168.1.6
192.168.1.4

srvdc01
IP Address. . . . . . . . . . . . : 192.168.1.4
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.1.1
DNS Servers . . . . . . . . . . . : 192.168.1.4
192.168.1.6

After the change run ipconfig /registerdns on both DC's and netdiag /fix.

Best regards

All DNS is AD integrated.

Hello Anderson,

I believe what is happening here is that you do not have a reverse zone
created for 192.168.1.x. This is actually not an error, but rather just a
message saying it cannot find a reverse entry for the IP address of the DNS
server it is using.

When nslookup initializes, it looks for a PTR in the reverse zone for the
DNS server that it is using for lookups. In this case, it is using
192.168.1.4. If you do not have a reverse zone, or if one exists, but there
is no reverse entry for 192.168.1.4, it will give you this message. Nslookup
will still work for resulting local forward lookups, and other lookups on
the internet, but it will give you this message each and everytime until a
reverse zone is created.

Re: DNS Server problem - nslookup DNS request timed out

Hi Ace

The reverse zone and ptr record is there. What could it be?

Re: DNS Server problem - nslookup DNS request timed out

If you receiving the message saying:
> *** Can't find server name for address 192.168.1.4: Timed out
> Default Server: UnKnown
> Address: 192.168.1.4


It means nslookup cannot find the PTR record in DNS. Apparently nslookup is
using 192.168.1.4 as it's DNS server. You mentioned that the reverse zone is
present along with a PTR for 192.168.1.4.

Did you confirm that PTR record exists on the DNS server located at
192.168.1.4? Curious, which "A" record is the PTR pointing to? Does that "A"
record exist in the Forward Lookup zone?

If you ping:
ping -a 192.168.1.4
Does it resolve the A record (the hostname)?

If you just created the PTR, exit nslookup, and try it again.

Also, do me a favor. Along with the above responses, please post an unedited
ipconfig /all of the machine you are trying this from, as well as from the
DNS (DC) at 192.168.1.4.

Thanks,

Ace

Re: DNS Server problem - nslookup DNS request timed out

Hi Ace

The DNS/DC is 192.168.1.4 and resolves fine using ping. I did find that the
PTR reccord was missing on 1 of 3 DC/DNS servers, event they should
replicate, with AD integrated zones. How can this happen?

Re: DNS Server problem - nslookup DNS request timed out

Hello Andersen DK AndersenDKdiscussions.microsoft.com,

For srvdc01 configure at least one of the other DNS as secondary DNS server.

For 4015 see here:

Hmm, the ipconfigs look fine. So there is a replication problem, it appears,
or maybe not. Do you see any errors in the directory service and NTFRS logs?

Curious, what replication scope are the zones set to? Please check all three
servers. The scopes must match. If they are different, then indeed it would
cause problems, specifically it will create duplicate zones in the AD
database, which can be one of the many causes of 4015's, 4515's, etc.

To check if you have duplicate zones, you can use ADSI Edit. Check the
DomainNC, DomainDnsZones and ForestDnsZones partititions. The following link
explains how to use ADSI Edit. I have more specifics concerning this issue
and can post the info, that is if this is the case.

Hi Ace

OK

Replication is set to "All Domain Controlers in the AD Domain", Allow Zone
Transfere to Servers in the Name Servers Tab, and notify servers in the NAme
servers tab. this is the same on all 3 servers.

The "To all domain controllers in the Active Directory domain" Option 3 from
the link.

however I did find a zone for a external domain, in both DomainDNSZones and
ForestDNSZones. would this be a problem?
