Air port won't resolve DNS server

I have been having problems getting my internet to connect automatically. It won't resolve the DNS servers on its own and I am having to keep entering them manually once the IP address have been found. Is there a way to fix this? I think I have all the settings on automatic.

Try using non-automatic servers.
In your DNS servers box in your network setup try these two 208.67.222.222, 208.67.220.220.

I have an Imac running snow leopard and have recently installed a cannon i-sensys lbp7750Cdn printer since then I can't get the printer working and the air port has lost the DNS servers; if it ever had them!!! but it dose not look happy. Can any one help

I have an Imac running snow leopard and have recently installed a cannon i-sensys lbp7750Cdn printer since then I can't get the printer working and the air port has lost the DNS servers; if it ever had them!!! but it dose not look happy and it is telling me so. Can any one help please?

Snow Leopard breaks quite a few drivers - my Canon exhibited the same problem.
I eventually found updated drivers on the Canon website. You can try that with the HP, but if the all-in-one is more than a year or so old, don't hold your breath.
You can also try Software Update to see if it will offer new drivers, or failing that go to the Support Downloads site and search for HP updates.
In fact there's a new one for HP at the top of the list just now.
You may not necessarily want the latest one, though - check the specs to see if your model is covered; if not, search for the previous update etc.

Air port extreme and windows home server

How do I set up my Airport Extreme to allow me to remotely access my Windows Home Server 2003?

The following are the basics for setting up an 802.11n AirPorts for port mapping/forwarding:
AEBSn - Port Mapping Setup
To setup port mapping on an 802.11n AirPort Extreme Base Station (AEBSn), either connect to the AEBSn's wireless network or temporarily connect directly, using an Ethernet cable, to one of the LAN port of the AEBSn, and then use the AirPort Utility, in Manual Setup, to make these settings:
1. Reserve a DHCP-provided IP address for the WHS.
AirPort Utility > Select the AEBSn > Manual Setup > Internet > DHCP tab
On the DHCP tab, click the "+" (Add) button to enter DHCP Reservations.
Description: <enter the desired description of the host device>
Reserve address by: MAC Address
Click Continue.
MAC Address: <enter the MAC hardware address of the WHS>
IPv4 Address: <enter the desired IP address>
Click Done.
2. Setup Port Mapping on the AEBSn.
AirPort Utility > Select the AEBSn > Manual Setup >Advanced > Port Mapping tab
Click the "+" (Add) button
Service: <choose the appropriate service from the Service pop-up menu>
Public UDP Port(s): <enter the appropriate UDP port values>
Public TCP Port(s): <enter the appropriate TCP port values>
Private IP Address: <enter the IP address of the host server>
Private UDP Port(s): <enter the same as Public UDP Ports or your choice>
Private TCP Port(s): <enter the same as Public TCP Ports or your choice>
Click "Continue"

Air port won't connect sometimes

Hi. I have a 15" MBP. Today i was trying to connect to wifi at a cafe, and even with almost full signal, I couldn't get online. I tried restarting several times, but still nothing.
Any ideas?
thanks

I also got the same problem, I just bought this new MacBook Pro yesterday. I use AirPort to connect my home internet router, it shows full connection but everytime after around 20 to 30 mins, all the connection goes off but the AirPort still showing full connection.
Then I have to switch off the AirPort first then on it again, the connection will be back to normal.
But every time I have to do this.
My room mate using a normal computer also connect to the same router but he has no problem of the connection. Only my MBP got this problem.
Now I use wire plug to the router and never get disconnect.
Will try to contact the Apple care tomorrow and see what they will say.

Internal DNS - emailsrvr.mydomain won't resolve, IP does - www works.

Internal Mail won't resolve to emailserver domain, but LAN ip is fine
Hey gang, longtime reader first time poster.
After wrestling with this issue, i'm about out of ideas.
Here's my setup.
Leopard server 10.5.4, running OD master (all rocking),
AFP, Firewall, DNS, (mobile) network home directories.
I'll call this "xserve.mydomain.com "
Its NAT'd IP is 192.168.1.102.
It's a FQDN, kerberos is running and happy, all is well.
There are about 12
clients, each with a desktop (imac) and laptop (macbook).
I have a second (windows 2003 sbe) server hosting the following
services: Exchange and Web (for now).
I'll call this winsbe.mydomain.com
Its NAT'd IP is 192.168.1.101
My External DNS setup is this.
Our DNS hosting is done by our registrar (network solutions).
We own 4 static IPs from our ISP.
One IP is for our router/firewall providing NAT
to internal clients, and the xserve is on DMZ, with
its OSX firewall service turned on.
One IP is for the
windows server. (the last two, if you've been counting, are unused .
Via Network Solutions "advanced DNS", I have our zone
configured. "xserve.mydomain.com" points to its WAN
IP (66.xxx.xxx.198).
www points to 66.xxx.xxx.194.
MX records refer to "winsbe.mydomain.com" via
WAN IP 66.xxx.xxx.194 as well.
All outside services resolve correctly.
IE, i can hit the website and send/receive email from mydomain.com.
My internal DNS as setup as this:
primary zone= mydomain.com
nameserver= xserve.mydomain.com
mx record= winsbe.mydomain.com
xserve.mydomain.com has an A record to LAN IP.
winsbe.mydomain.com has an A record to LAN IP.
www is a CNAME record to winsbe.mydomain.com. <----i'm not sure about this one but it works.....
My forwarder IP points back to my Router (which seems to give me better performance than using ISP
DNS from here..)
I know this is working fine insofar as the webserver, as
an nslookup (www.mydomain.com) internally resolves www to 192.168.1.101.
mydomain.com and www.mydomain.com hit the webserver internally
on client browsers. rock.
Again, forward AND reverse nslookups internally resolve to winsbe.mydmain.com/92.168.1.101
Here is my guess as to my problem,
my internal hostname + a record for the windows server the same as the MX record
which has an alias from www.
I think it's getting effed in there somewhere?
If I setup email clients with the windows server LAN IP rather than
the domain "winsbe.mydomain.com" it all works fine.
I'd frankly be willing to half-*** it with this solution,
but each client will require a mobile computer, so we can't have that
I feel like i'm on the right track, but
just can't make the breakthrough.
Am I barking up the wrong tree here?
Here is a last question,
I have my firewall/router as the "Forwarder IP Address"
in the last page of Settings in server admin. When i put
my ISP's DNS servers, i always get a 2 second delay
for any web query on any client.
I have "127.0.0.1" as the first DNS entry in xserve Network Preferences.
The xserve is the only DNS entry in the client computers.
This isn't a "bad practice" or anything is it?

For the curious, my named.conf below (haven't messed with it):
// Include keys file
include "/etc/rndc.key";
// Declares control channels to be used by the rndc utility.
// It is recommended that 127.0.0.1 be the only address used.
// This also allows non-privileged users on the local host to manage
// your name server.
// Default controls
controls {
inet 127.0.0.1 port 54 allow {any; }
keys { "rndc-key"; };
options {
include "/etc/dns/options.conf.apple";
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
// query-source address * port 53;
// a caching only nameserver config
logging {
include "/etc/dns/loggingOptions.conf.apple";
// Public view read by Server Admin
include "/etc/dns/publicView.conf.apple";
// Server Admin declares all zones in a view. BIND therefore dictates
// that all other zone declarations must be contained in views.

Resolving arabic domain name in Solaris DNS server

Hi..
I just quickly want to know how can i define arabic font domain name to get resolve in my DNS server?
I tried to put entry with arabic name but editor making it abnormal, i recently get arabic locale installed on server through north Africa region. Locale is now showing me "AR" ..
Thank you

Sorry my bad.... slight mistake in my question...Here is my corercted query--
After successfully connecting to the internet, when I do NSLOOKUP on the DC, the DNS doesnt resolve my internal domain/site but instead resolves external sites on the internet.
My computer FQDN is nri.wwe.com
Domain dns name is wwe.com
The above should get resolve internally but it searches on the internet.
This is how it should work
& it works perfect when I disable the other NAT network adapter (i.e. disable internet connectivity on my virtual DC)
C:\>nslookup nri.wwe.com
Server: nri.wwe.com
Address: 192.168.1.11
Name:    nri.wwe.com
Address: 192.168.1.11
But when I again enable internet connectivity, this it what happens.
C:\nslookup www.wwe.com
DNS request timed out.
    timeout was 2 seconds.
Server: UnKnown
Address: 192.168.12.2
DNS request timed out.
    timeout was 2 seconds.
Non-authoritative answer:
DNS request timed out.
    timeout was 2 seconds.
Name:    www.wwe.com.nsatc.net
Address: 64.152.0.124
Aliases: www.wwe.com
And when I again nslookup, this is what I get,
C:\>nslookup www.wwe.com
DNS request timed out.
    timeout was 2 seconds.
Server: UnKnown
Address: 192.168.12.2
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to UnKnown timed-out
Now this 192.168.12.2 is VM assigned DNS via VM Natting with its own DHCP. If we do it manually, none of the virtual machines can connect to the internet. So I cannot fiddle with it anymore as I have already that as well.

DNS won't resolve SRV records with recursion disabled

I have DNS installed on a Windows Server 2008 R2 server. I have a standard zone created (no AD integration). I have recursion disabled. When I use NSLookup to lookup any of the A records or CName Records the results are returned as
expected. However, if I attempt to lookup any SRV or MX Records, the list of root hints are returned (which is what I would expect if I was attempting to lookup a domain not hosted on this server). Now I enable recursion and run the same exact
commands and I get the results I'm expecting.
I'm stumped.....
DB

Reader's digest version: Putting a period at the end of my record, resolved the issue. This seems to be a difference between Windows 2003 and Windows 2008R2
Long version:
Thanks for the debug tip. That confirms the issue. So to backup a little, I had a Windows 2003 box running DNS. I planned on decommissioning this box; therefore, I stood up the second server, made a secondary DNS zone, once all records
transferred, I flipped the primary and secondary roles.
The real problem is this zone cannot find any of the TXT records such as SRV and MX. When I run NSLookup with recursion disabled, my results are:
    HEADER:
        opcode = QUERY, id = 18, rcode = NOERROR
        header flags: response, want recursion
        questions = 1, answers = 0, authority records = 13, additional = 3
That makes perfect sense why recursion is working. If I run the same results on the secondary DNS server (the original server) the results are expected:
    HEADER:
        opcode = QUERY, id = 20, rcode = NOERROR
        header flags: response, auth. answer, want recursion, recursion avail.
        questions = 1, answers = 4, authority records = 0, additional = 4
SO THE REAL QUESTION is why can't the new server find these records, especially since it's a copy of the zone from the old server. I flipped the servers back, deleted the DNS zone (and files) on the new server, restarted DNS service, created the zone
again, and allowed the content to copy over from the old server and I STILL get the same results.
The last thing I did was created a new SRV record on the new server and performed another NSLookup, but still get the same results.
So then I remembered
MuhammadUmar's post about putting a period at the end of my nslookup command. I honestly didn't that that was going to change the results, but BAM. I was wrong. When I put in the request with a period at the end of the record, I get the
results I'm expecting.
Thanks all for helping me on this one!

Just resolved Back to my Mac issue called Apple Suppport in the UK and they were really helpful if the error DNS server not responding the problem is with Apple server not your server ( I had tried to reboot by router, restart my laptop etc.

I was having problem with my Back to my Mac as message was saying DNS Server not responding . I tried to turn my WIFI off, then my router to no avail. Decided to call Apple Support line in the UK . I got a call back immediatly and great support. The advisor took over my screen and we check that my laptop was synchronising with I phots and it was. The adviser also told that when the message DNS server is not responding next to Back to my Mac is has to do with Apple Server not mine , router etc... Hope this save others some time! Rather than spending time truining on and off changing IP address etc...

Thanks for your thorough post. I too need to use BTMM on almost a daily basis for my job, and it has fallen short countlness times. I too have taken great pains to check all of the typical trouble shooting steps within iCloud and in the Apple keychain on each Mac etc, but after the latest rounds of system updates from Apple a few weeks ago to Mountain Lion, BTMM on one of my Macs is completely broken and unusable. I would concur that if you need remote access for "real" mission critical use, just bite the bullet and pay for a service like LogMeIn. You won't regret it and you will get real software support.

DNS Server - How does it resolve queries that aren't in it's zones?

Footy wrote:
Also if you have multiple DNS servers pointing at each other and no root hint or forwarders you get stuck in a loop of the two machines querying each other over and overNo. It doesn't. If the DNS server has no forwarders or root hints then it doesn't know how to get any further answers to the query so it returns a negative response. Read RFC 2308.

So I'm trying to learn more about the basics of DNS, specifically DNS servers as that's what I'm having trouble with in my environment and trying to learn more about to fix.I know what DNS is and I think I have a pretty good handle on how it does what it does, but where I'm having trouble keeping up is figuring out how it resolves things outside of my local domain.For example, everything I've seen in searches says that if you've got two DCs on your domain you should have it set up like this:On DC1:DNS1: DC2DNS2: DC1On DC2:DNS1: DC1DNS2: DC2And you should have the workstations in your environment set with DC1 and DC2 as their primary and secondary DNS servers. Is that correct?If it is correct, then what happens when someone in the network goes to say www.google.comconsidering I don't have that name or IP address in my server's lookup...

DNS Server does not resolve new generic Top Level Domain names- CNR configuration issue?

Hi all,
I am not sure if this is the correct community to post this question, but I will give it a try. I noticed that the users of my network cannot resolve web sites using new top level domain names, like ".education", ".international", etc. I have an internal DNS server made by Infoblox and a Cisco CNR v6.3.3.1 as an external DNS server. Infoblox uses CNR as its forwarder and CNR uses the root DNS servers for queries.
I would think that CNR was the problem because it is an obsolete product but after speaking with a fellow engineer at another organization where they still use an older version of CNR than mine, they have no problems at all. So now I am thinking it is a setting either on Infoblox, or on CNR I need to change. I can see Infoblox is forwarding the requests to CNR but that's about it. I am not sure if CNR is discarding the request. When I do an nslookup from a PC in my network it does not matter if I set my DNS server to be the Infoblox or the CNR. Neither resolves the URL.
Then again, no matter what I lookup using the CNR as my DNS, I only get a response with the root DNS names and IPs!
Any help is appreciated!

Hi Constantinos,
Have you taken a look at the infoblox community site? We've just reposted your question there and alerted some internal SMEs that should provide a solution soon.

How a router can resolve dns without ip name-server command?

Hello everyone,
A question about the command "ip name-server *.*.*.*"
If I didn't put in the DNS server, the router can still resolve the domain name. You can see the domain server is 255.255.255.255.
Why does this happens?
R4#ping www.cisco.com
Translating "www.cisco.com"...domain server (255.255.255.255) [OK]
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 184.31.192.170, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms

Hi,
There is a name server inside the LAN. Before searhing in the DNS server, it checks the name server in the LAN to reduce the time for searching. The name server of the LAN is like a cache which stores the results coming from the DNS server.
So, it is name server of the LAN which is resolving the IP address.
Thank you.

Air Port Express as print server

Hi,
I am looking for a system that allows me to print wirelessly from two macbooks and one vista to my dell USB printer. I have a wireless G network running (dlink router) and I was wondering if an an air port express could be used as a print server?
So would it pick up the signal from my router so that I can print wirelessly?
thanks,
Alexander

Yes. The only issue is printer compatibility. Check out this link:

Default DNS server unknown its coming while resolving`

Hi
i have windows 2012 domain controllers, able to successfully resolve dns queries.
But the problem is while resolving default server field its coming unknown. i created reverse lookup for dns server(Domain controller) after that host name is coming..
But after one day again hostname disappeared, default server field unknown coming..
If anybody knows this issue..

Hi,
Have you checked if the reverse lookup record is still present in the reverse lookup zone. Domain Controllers use dynamic registration to register A/PTR records for itself. Make sure Enterprise Domain Controllers group has permissions over the records so
these can be updated. This is found in on the security tab at the record/zone propetties. If you manually created the PTR record then it should have no timestamp therefore it will not be scavanged in case you enabled that function.
Hope this helps.

Calin

[URGENT!!!] DNS won't resolve. PLEASE HELP!!! [DESPERATE]

guys,
i googled, read the DNS & BIND book (very useful), but still haven't solved my problem and this is killing me as i have spent days and the darn thing simply refuses to work!!! i am desperate and need your help.
i am trying to set up a DNS server on my dual NIC x86 Solaris 10.
1. i am getting confused with naming interfaces. i seem cannot have two network ifaces named like m1.example.com. each one must have its own unique name, right? [pls advise here]
so i name them m1.example.com and m2.example.com respectively. m1 is for router and m2 is for switch (LAN).
m1.example.com - 10.0.0.2
m2.example.com - 192.168.16.1
2. secondly I cannot get the SOA record. what interface should be used as SOA?? i tried m1 as it is "primary" (iprb0) and connects to the internet. however, it didn't work.
i even tried m3.example.com trying to combine two interfaces as below (still won't work):
my db files (excerps, server is down, writing from home) :
DB.EXAMPLE.COM
$TTL 3h
@ IN SOA m3.example.com. admin.example.com. ( 1 3h 1h 1w 1h)
IN NS m3.example.com.
localhost IN A 127.0.0.1
m1.example.com IN A 10.0.0.2
m2.example.com IN A 192.168.16.1
example.com IN MX 10 m3.example.com
m3 IN A 10.0.0.2
IN A 192.168.16.1
DB.10.0.0$TTL 3h
@ IN SOA m3.example.com. admin.example.com. ( 1 3h 1h 1w 1h)
IN NS m3.example.com.
1 IN PTR m3.example.com
DB.192.168.16$TTL 3h
@ IN SOA m3.example.com. admin.example.com. ( 1 3h 1h 1w 1h)
IN NS m3.example.com.
2 IN PTR m3.example.com
DB.127.0.0$TTL 3h
@ IN SOA m3.example.com. admin.example.com. ( 1 3h 1h 1w 1h)
IN NS m3.example.com.
1 IN PTR localhost.the previuous incarnation of the files contained m1 instead of m3 as SOA and NS, but like i mentioned already, it didn't work either.
i am able to ping router 10.0.0.1, but can't surf.
when i nslookup m3.example.com it gives:
Server: 127.0.0.1
Address: 127.0.0.1#53
Name: m3.example.com
Address: 10.0.0.2
Name: m3.example.com
Address: 192.168.16.1and if i nslookup m1.example.com and m2.example.com it gives proper addresses (10.0.0.2 and 192.168.16.1 respectively).
DNS is running and files don't return errors after named-checkzone.
the idea is to make DNS server work for local network (192.168.16/24) and install postfix on top. however i am stuck with DNS at the moment.
please, anybody point me in the right direction - need to get this working by tomorrow!!!!!
many thanks for your replies.

Whats your named.conf look like? Also, google DNS forwarder/forwarding....
