DNS server configuration and behaivour

Hi all,
I'm looking for detail explanations which can explain how Mac OS X 10.6 *DNS client* works and may be configured.
According to http://discussions.apple.com/thread.jspa?threadID=2227251 nothing is not guaranteed like order and failover.
According to http://support.apple.com/kb/HT4030 failover will take affect when DNS server returns with SERV_FAIL (0x2) error code. What about NXDOMAIN (0x3) error code (which is more interesting scenario)?
What I'm looking for DNS client?
I'm looking for several DNS servers configuration which allow to split DNS domains for several areas. This, for example, may be very useful for VPN connections when VPN DNS server will resolve internal resource and another server (configured before VPN tunnel established) will resolve external resources.
Is there any possible configuration to achieve this requirement for Mac OS?
Thanks in advance,
Oleg.

Thanks Felix for quick response.
In your scenario:
1. You configured to different DNS servers and probably only one of them replied to DNS queries. And this is OK.
2. When non valid IP configured means that DNS server will not reply to DNS query and than failover will query the second DNS server in the list. And this is also OK.
I'm looking 2 different DNS servers configuration when one of them will reply to different domains. For example:
First server will reply to *.mycompany.com.
The second one will reply to any query except mycompany.com domain(since it is not published).
Thanks again,
Oleg.

Time Capsule blinks yellow,when I go to airport utility to set up, it Says This apple wi-fi bse station doesn't have any DNS server addresses and might have trouble connecting to internet. My internet works, but I can't back up anything. What do I do??

Worked fine for about a couple of weeks after my son -law installed the time capsule. I can access the Internet both from my wife's I phone and from my desktop. I think that I need to get the DNS server numbers and put them in the two blanks; but where do I get them? Thanks, Jim

If the modem is also a router, either use the modem in bridge and run pppoe client on the TC.. that is assuming ADSL or similar eg vdsl. If it is cable service.. and the modem is a router, then bridge the TC.. go to internet page and select connect by ethernet and below that set connection sharing to bridge.
Please tell us more about the modem if the above gives you issues.

"Back to my Mac isn't working properly because your DNS server isn't responding. Contact your ISP for an alternate DNS server address, and enter it in Network Preferences".

Hi, i am trying to setup back to my mac at home but I get the error "Back to my Mac isn't working properly because your DNS server isn't responding. Contact your ISP for an alternate DNS server address, and enter it in Network Preferences".
There is no documentation on how to solve this anywhere.
I have an Arris router set to bridged mode which is connected to a 5th generation airport extreme. I have tried using the google dns servers instead of the one assigned by the cable company in the AE but I still get the same error.
Any help would be much appreciated

New to BTMM, I got stung today with the silly DNS problem message. Solution:
1) Flush DNS cache with:
dscacheutil -flushcache;sudo killall -HUP mDNSResponder
2)System preferences > iCloud > untick BTMM then tick it again. The warning should have disappeared.
Edit #1
Apologies for the noise. The warning has come back
Edit #2
Just found out that BTMM is not compatible with double NAT. That's not helpful.

InDesign Server configuration and fonts

When you start multiple instances of InDesign Servers you specify the different configuration names.
Is it possible that 2 instances of InDesign Servers running on the same server with different configuration names have different fonts installed?
I.e. can I install some fonts of configuration level, not for the entire server?

There is no document titled "InDesign Server Installation and Configuration Guide". This was an error in the CS2 version of Introduction to InDesign Server.
You'll find the CS2 version of Introduction to InDesign Server in the InDesign Server CS2 ESD (the server download bundle). Even better you'll find the CS3 version in the InDesign CS3 Server SDK. Available at the following URL:
http://www.adobe.com/devnet/indesign/
The information about Java/CORBA is specific to CS3, but the information about scripting and SOAP applies to CS2.
Let me know if that helps, or you still need something else.

LDAP-Server configuration and using

Hi,
can anyone tel me how it function with the LDAP-Server in the Adobe LiveCycle Es?
What i have to do? and how can i get user data from the logged user via LDAP?
Thank

LiveCycle ES has an administrative console you can get at http://localhost:8080/adminui. You can log in with administrator/password.
Under the Settings section, you can go to User Management and then Domain Management.
In there you can define a new Enteprise Domain and create a new Authorization and Directory for that new domain.
In the Authorization, you can select LDAP. Under the Directory, you'll be taken through a wizard that will help you configure the LDAP connection to get the list of users and groups.
Then go back to Domain Management and select "Synch Now". You can set that synchronization to occur periodically.
Once you can connect to the LDAP server properly and get the list of users, you should be able to log to the different interfaces using users from the LDAP system.
You might need to give them LiveCyle roles to access some of the interfaces like adminui, workspace, etc. You can add roles under Settings/User Mangement/Role Management

DNS Server (Nameserver) and Webhost

I just had a quick question about DNS services. I currently have a Mac Pro that is running as a web server. Is it possible to run this as a DNS server as well, or should I just throw up a second machine to do that for me? I know the latter is preferred, but I'd prefer to run only one server at the moment if possible.
If that is possible, is it possible to make the dns server the same domain as the website. So if the server is server1.example.com, and hosts dns services, can it also host a website for example.com?
Thanks for the help. I've never really had to deal with trying to put everything on one machine, and this is my first attempt at a Mac Server (though I get the majority of it because I'm coming from Unix servers.)

Is it possible to run this as a DNS server as well
Sure. DNS is a pretty lightweight service. It won't tax your server, even if you're serving millions of page views per day.
is it possible to make the dns server the same domain as the website
Sure. Why wouldn't it?
There is no relationship whatsoever between the domain(s) hosted by the DNS server and the web sites hosted by the web server. They can be the same, they can be different, none of it matters.

DNS server configuration

I used the following commands to enable DNS server on my 2651XM router running IOS 12.4(1a - C2600-ADVENTERPRISEK9-M):

Discovery Server - configuration and abap changes allowed?

Hello -
We are thinking about deploying a ESA Discovery Server, specifically for exploring ERP 2005. We may use this as a way to get one of our project teams busy doing proto-types, while we build out a true ERP 2005 Dev/Qual/Prod environment for them.
I anticipate that some of our project team members will want to create transports of config and/or ABAP code. And, would ultimately like us to export/import this into a DEV system, once it is built.
Is anyone aware of any restrictions for using the ESA Discovery Server, in a fashion like this? Or, any restrictions about importing transports into the ERP 2005 instance within Discovery Server (except the obvious version compatibility issues, etc.)
thank you,
Steve

Hi Steve,
As long as you ahve the appropriate ABAP development licenses you should be fine. The software which is installed is the exact same software which you will later download from service marketplace or obtain via DVD from SAP. Therefore, technically it should work fine. Of course, you will need to ensure the transport mechanism is configured properly for your environment.

My Airport base station has a status message that says "This AirPort base station doesn't have any DNS server addresses and might have trouble connecting to the internet." What does this mean and how can I fix it?

My internet is still working, but it's very intermittent. This happened after I updated the firmware a few days ago.

Did you remember to completely power cycle the entire network?
You would want to do this after any update or change to the network.
If you did not do this yet......things are out of sequence.
Power off everything on the network.....all devices.....power down order is not important
Wait a few minutes
Start the modem first and let it run a minute or two by itself
Start the next device connected to the modem the same way
Work your way out on the network starting each device about a minute apart
Check the network

DNS Issues - Can ping server name and IPs but not FQDNs.

Hi All,
Hopefully some one can help me here, I am having an issue where one of my domain attached servers cannot ping any FQDNs in the environment but it can ping the host names and the IPs and look up the host names from a reverse look up.
We have done the following troubleshooting:
Flushed and registered DNS cache.
Restarted the DNS client and net logon services on the effected server
Preformed standard checks and commands such as:
Checked the event logs and found there were warnings for DNS registration.
Compared the DNS settings in the network adapters across the rest of the servers in the environment and found that they were all the same. DNS Suffixes are added in the correct order and are set to register.
Pinging FQDNs which is not giving any results.
Tracert FQDNs which is also not giving any results.
Nslookup which is querying the DNS server directly and giving results as expected
Ran the command which reported successful: dcdiag /test:registerindns /dnsdomain:sub.domain.net /v
Checked and updated the permissions on DNS for the affected server to give the server full control of its own DNS entry.
Replaced the DNS Client service DLL with one from a server that is working as expected.
Also worth noting is that the affected server (as well as every other server in the environment) has 2 NICs, one that communicates with DNS and AD and the other does not have any DNS IPs set.
Not this is not the first time this happened, a reboot fixed the issue before but it seems to be a reoccurring problem now.
If any one can shed some light on this issue I would be grateful.
Regards,
Steve.

Hi Steve,
First, we should confirm if this issue is caused by DNS.
When you ping the FQDN, does the server show the correct corresponding IP address?
If no, there should be some error messages. If it is possible, please post the screenshot of this issue.
To check the process about how does server resolve the FQDN, please follow the steps below:
clear local DNS cache with command ipconfig /flushdns
perform the network capture
ping the specified FQDN
Check the DNS traffic

Besides, have you tried to update the NIC driver to the latest version?

Hello I'm having a no dns server problem on my time capsule

Hello I'm having this same problem:
Sammy Stefanki
Apr 11, 2012 2:20 PM
Hi everyone,
I just bought a new AirPort Express and Comcast is my ISP. I ditched my old Belkin wireless router, connected the Comcast modem directly to my AirPort Express, and it appears to be working great. I can access the internet wirelessly and also play music using AirPlay through my stereo speakers.
However, when I open the AirPort Utility, the utility tells me that I have two problems with my AirPort Express:
Apparently I have no internet connection (the utility tells me that "Your AirPort base station does not have a valid IP address."), even though I can access the internet just fine.
I don't appear to have any DNS server addresses (the utility tells me that "This AirPort base station doesn't have any DNS server addresses and might have trouble connecting to the internet.")
Does anyone know if these are serious problems that I need to address, or can they be ignored? I don't want to start tinkering with the AirPort Express's settings until I am better informed, because right now everything is working as far as my access to the internet is concerned.
and I tried to :

Anytime you change networking hardware, it is always a good idea to perform a complete power recycle of your networking components.
I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.
BUT NOTHING IT STILL SHOWS NO INTERNET CONNECTON on my capsule and NO DNS SERVER ...
I have tried to HARD RESET it resets ( with a Network Name (SSID) of Apple Network NNNNNN) and it connects to internet, it also says setuo complete in airport utility but once I go back into Airport utily cause Time capsule is still flashing amber it says NO INTERNET CONNECTION and NO DNS SERVER ...
anyone has any suggestions PLEASE and Thank you

Check the Ethernet connection to the AirPort Express. Make sure that the Ethernet connection from the Comcast modem is connected to the WAN port on the back of the AirPort Express. The WAN port is the one with the circle of dots shown over the port.
It sounds like you are connected to the Ethernet LAN port.

Can't override DNS Server settings - can only append!

See this thread for a similar question:
http://discussions.apple.com/thread.jspa?messageID=3555096
I have also filed this with Apple (Problem ID 5159216). Here is the text of the report (with a few bits removed - not crucial to understanding the report).
If anyone has suggestions/clues to resolve, please advise. Thanks!
Summary:
This problem concerns AirPort Extreme (802.11n) at revision 7.1. I will summarize with a comparison between AirPort and MacOS X.
MacOS X and Airport Extreme (referred herein as "AE") both permit editing of DNS server settings whether in DHCP or Manual mode.
When MacOS X DNS server settings are set manually by the end-user, the new server IPs are used (good). When AE's DNS server settings are overridden by the end-user, the new server IPs are NOT used (not good)! Rather, the DHCP-supplied DNS server always pre-empts whatever is given in the AE Configuration UI.
Steps to Reproduce:
1. Using AirPort Extreme (802.11n) at revision 7.1 and MacOS 10.4.9 on a MacBook Pro (Core 2 Duo). The AE has been previously configured for IPv4 using DHCP and the MacBook is successfully connected and resolving domain names through the AE.
2. Visit "Apple Menu > Location > Network Settings" and check the AirPort TCP/IP settings. For purposes of this test, make sure the "DNS Servers" field is EMPTY so MacOS X defaults to the AE's DNS settings, then close System Preferences.
3. Run "AirPort Utility" (the newer version, not "Airport Admin Utility") and configure the AE under test. Pick the "Internet" icon in the toolbar and note the Internet Connection settings.
4. In this test, Configure IPv4 is set to "DHCP" and the DNS Server(s) field contains two DNS IPs assigned by the Internet Service Provider. In my case that's Cablevision's Optimum Online service. You may or may not see IP addresses here, but in my case they are visible.
5. As the DNS Server(s) are editable, and they both show ISP-supplied addresses, they can be changed to whatever alternate IPs you wish. For instance, change them to these alternate DNS IPs from OpenDNS.com: 208.67.222.222 and 208.67.220.220. (You could use any alternate set of IPs but for the purpose of this test use the OpenDNS IPs.) Update the AE and restart.
(For additional reference, http://www.opendns.com/start/airport.php shows instructions for the older AirPort Admin Utility, but the concept is exactly the same.)
6. Normally you shouldn't have to restart the MacBook Pro since we're just using the AE settings, but go ahead and do that just to be consistent with this test.
Expected Results:
Now for the moment of truth! We want to verify that we're using the OpenDNS IPs for our DNS Servers. One nice feature OpenDNS has is automagic redirection for certain domain name typos.
Here's an example. Drop to shell (Applications > Utilities > Terminal) and try this command (excluding the $ prompt, natch):
$ dig craigslist.og
The "og" typo is deliberate. We really want to go to craigslist.org. If you're using the new OpenDNS IPs, you will STILL get an Address (A) record with an IP like so:
;; ANSWER SECTION:
craigslist.og. 0 IN A 208.69.32.130
If you had entered "craigslist.og" in Safari, you would end up at 208.69.32.130 (an OpenDNS server) and then redirected to craigslist.org.
Actual Results:
Alas, that's not what happens! Instead, you get NO IP address, like so:
;; QUESTION SECTION:
;craigslist.og. IN A
This means we're not actually using the OpenDNS IPs. What's happening?
To find out, I spoke with the AirPort support group (Case # xxx-xxx-xx). I learned that, despite being allowed to edit and override the IP addresses provided via DHCP, the AE still uses the DHCP-provided DNS server if available.
Again, the user interface suggests that I'm allowed to override the DHCP-provided DNS IPs as shown in the UI. Even though I can do this, the AirPort will still keep note of any DHCP-provided DNS Server IPs and use those first.
True, I can switch to Manual network settings (and then my own DNS Server IPs take effect). Of course this is problematic when the ISP renews my IP address (which it does from time to time).
Another workaround is to use the "DNS Servers" settings noted in step 2 (above). However this is also problematic if I want to keep my network settings simple. It requires a "Home Network" location and an "Office" location. Still not preferable, but it's a workaround.
Regression:
n/a
Notes:
I would like AirPort's DNS settings to be overridden in the same way OS X allows DNS settings to be overridden. The user interfaces suggest this is possible but it is not. It's only possible in the OS X case. Having the same flexibility on the AirPort would be most welcome.

Afraid of the answer...sheesh...you must be a child. This has nothing to do with masquerading anything. The issue being discussed here is that people want to manually assign a dns server address via the new AEBS, while maintaining DHCP for IP address assignments through their ISP. For example, I would like to have opendns.com take care of all dns addressing at the router level, even though I have "Configure IPv4" set to "Using DHCP". If you do not understand why one would want to use something like opendns.com, please visit their website and enlighten yourself. The fact that the dns server address fields are editable when set to "Using DHCP" leads one to believe that you can manually assign a dns server in this configuration; however, under firmware 7.1.1, you still cannot. The previous iteration of the airport hardware can do it, as can nearly any router you pull off the shelf. In addition, this is something that can easily be done at the individual-computer level in OS X; however, many people would prefer to administer their network at the router level. That is the issue being discussed here. Either you can't read or you are purposely derailing the thread.

How to use DNS server for name resolution for items which don't exist in active directory domain controller DNS

Dear Experts,
In our office we have a domain controller call it 'Office.com', all computers and corporate servers e.g. exchange, antivirus etc. are member of this 'office.com', it is also having a DNS. All users in office have there preferred DNS set to the corporate
DNS
We are working for ministry and offering services to them from our data center so have many servers which are for ministry but they are in our data center. For all these servers we created another DNS server which contains all entries for these servers in
forward and reverse lookup zones. In this DNS we also created a forward lookup zone for our corporate servers and zone name is 'office.com'
What we are trying to have is name resolution of all servers which are listed in other DNS build in our office on Win 2008 R2 for ministry servers
If the user change his preferred DNS to ministry DNS he can resolve the ministry server but then we can not control any thing through group policy since they are using other DNS and not the corporate DNS.
How this can be done ? like any group policy applied to corporate domain controller must take effect on users and in addition to this user must also be able to resolve server names in ministry project DNS
Please assist ASAP.
regards,

Hello,
ok so the GPO setting doesn't apply in any case.
Clients machines use the first DNS server in the list of configured ones on the NIC. If that one is available search for additional DNS servers will stop.
What i can not really understand is your description about the second DNS server. This should normally either another DC with AD integrated DNS, so everything is replicatedwithin AD replication or you use a secondary DNS on domain member server that pulls
the informations from the Master.
It sounds for me that you have configured a machine with DNS server role and created manually the zone with the same name as the domainand manually create there the required A records?
