DNS Server Problem

Hi,
I'm running Windows Server 2008 R2 and Windows 7 Enterprise on Virtual Box both are 64bit versions.
I setup the AD DS and the DNS Server role on the server and set the server IP addresses as follow:
IP: 10.0.2.16
Subnet: 255.255.255.0
Default gateway: 10.0.2.2
DNS: 127.0.0.1 (to itself)
On the Win7 machine I let the IP addresses be obtained automatically and set the DNS server IP manually as 10.0.2.16 (the IP of the server machine). IP addresses from the Win7 machine:
IP: 10.0.2.15
Subnet: 255.255.255.0
Default gateway: 10.0.2.2
DHCP Server: 10.0.2.2
DNS: 10.0.2.16
But I still can't ping to the server. It says "request timed out" once and then "reply from 10.0.2.15: destination host unreachable"
I'm trying to join the Win7 machine to the domain on the server. But I get the error "the domain could not be contacted" every time. The details of the error is that the DNS server are not responding.
My guess: there is some problem with the DNS server setup but I don't know exactly what it is and how to resolve it.
Thanks for any help!

Thanks a lot!
I changed both machines to bridged mode.
I can now ping the DNS server from the Win7 machine. That was just stupid from me, got me stuck for 2 days...

  • DNS Server problem with AX

    my network only consists of the AX, my macbook, and my PC (which is rarely used anymore). At least once a week, sometimes more often, my AX reports a DNS server problem. I've plugged it in to the ethernet and the settings are they same and there is no other router involved. The AX is connected directly from the cable modem. I confirmed with my ISP that the DNS server numbers are correct and they show up in the proper fields as well. What may cause this and how can I fix it?

    Welcome to the discussion area!
    Since the Express can only use the information that it receives from the ISP,
    you might want to try the Open DNS settings to see if that will help. Just be sure to make note of your current settings in case you need to revert to them.

  • DNS Server problems with ASA 5505

    Hi guys,
    we setup a new ASA 5505 which is mainly used as our VPN gateway. The ASA is configured and controlled by our ISP (and this is where the problem starts )) and they somehow cannot manage to get the VPN settings really working.
    So, here is our problem.
    our machines(Windows 7) are configured to get the network settings through DHCP (Windows 2012 Server).
    Before I connect with AnyConnect to our VPN gateway, the DNS Server setting in the network settings for the adapters(IPv4) are set to 'dynamic'
    When I now connect, this setting is changes to a statc entry (which is our DNS server).
    When disconnecting, it is not reverted back, which means I have to do this always manually.
    What I do not understand is the fact, that the DNS server is set for all the adapters, shouldtn't it be only set to the anyconnect adapter?.
    The interesting thing is, that when I connect to a different ASA, this does not happen. The ISP is now saying, that the machines are configured exactly the same and that they cannot reproduce, but I can't believe this.
    This issue shows up at every machine which connects to our vpn, so it is not only a single machine which might be misconfigured.
    Do you have any idea what might cause this issue?
    btw, the second ASA (which works) is from our partner company, so we cannot simply copy the config
    THanks in advance
    Patrick

    Nice to see someone from BT has addressed your issue 
    I have this exact same problem, seems completely bizarre, I'm pretty sure I had the same problem with the original home hub (i have the latest one now). Can you confirm whether the problem does affect anyone with a bt home hub and not just the one that the dyndns is pointing at? I'll try and confirm by hitting your domain from my home connection.

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

    Hello I'm having this same problem:

    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.

  • WRT54GS v6 DNS Server problem

    Running this router for 2 years without any problems (even on Windows7 since las year), recently it won't let me conect to the internet, Network and Sharing Center say that the pc's configuration are alright but no DNS Server response is present.
    (Windows 7 Ultimate x86 RTM, Bellsouth/AT&T ISP in Florida, US. DSL conexion, brand new ethernet cables and hardware kept in the best shape, Network Adapter: Realtek RTL8102E/RTL8103 Family PCI-E Fast Ethernet NIC (NDIS 6.20)(v7.2)
    ================================================================================
    What I tried:
    Resetting the router and/or modem (connected to a Westell 6100), setting both to default settings over and over (Web based reset and reset buttons)
    IP Flushing in CMD
    Getting to the web based configuration for my WRT54GS v6, releasing DCHP, renewing, default settings, etc...
    Upgrading firmware to v1.52.7 (latest) to no avail, going back to original 1.52.6.
    Device manager shows hardware working properly.
    Windows 7 shows me a link to look at the properties of my WRT54GS, when I right click on it, I can also see the option "Enable", but everytime I use it I get "Connection Failed!"
     ===========================================================================================
    I'm not much of a tech guy, and reading the forum didn't help me much, so I'm asking for some help please.
    Ps: Installed default CD for it with its old EasyLink Advisor to no avail, also tried the latest Lela 2 EasyLink Advisor to no avail.
    Also, there was no Default Gateway looking at an IPCONFIG in CMD, and now there is (192.168.1.1), which I use to get into its web based configuration.

    Solved!
    Go to Solution.

    As your ISP is an DSL provider, Most of the DSL Modem has a DHCP on them, so they acts like an Router. So right now you connection type is NAT behind NAT.
    To make your Linksys Router work with an DSL Modem. Login to the Linksys Router setup page and below the setup tab you need to change the "Local IP Address" to 192.168.2.1 and click on Save Settings... 
    Once the settings are saved, unplug the power from Router and Modem, wait for 30sec and then plug the power to the Modem and once all the lights are lid then you can plug the power to the Router and check if you are Online. 

  • 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.

  • Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding [and I'm at my wit's end!]

    I originally posted this question to the community section and was advised to post it here.  Please bear with me as this will be a long post.  I'm including the scenarios involving this reoccurring issue, the trouble shooting steps I've already
    taken and the results of several diagnostic tools and logs.
    I have a Sony VAIOS VPCEBB33FM lap top since 2011.  I have had this issue on an off for a long time.  I'm at my wit's end.  Any new insights or suggestions would be greatly appreciated.
    Scenario Details
    1)  Some times it's on and off through out the day, sometimes it won't work all day, and once in a while it will work fine for the entire day.
    2)  I've had this issue across several wireless services, Clear Network accessed with WiMax, Library Wi-fi, Comcast cable internet using wireless router and Wi-fi, and Comcast Xfinity Wi-Fi, to name a few examples.
    3)  Other devices in the household or library will work with no problems such as my smart phone or my roommates' laptops or desktop computers.
    4) Once in a while,  the built-in wireless adapter is not found and I have to reinstall the driver.  Also the diagnostic tool has had to reset my adapter on an increasing basis.
    5)  I had my hard drive replaced in December 2014 and my system restored from the System Restore disks that came with it when I bought the laptop.  Even though I've been online on an infrequent basis it worked just fine for a while. Now that
    I've been online a bit more I'm having the same issues again.
    Below are my attempts at trouble shooting so far but I still have not been able to consistently resolve my DNS issues
     1) Restarting my adapter
     2) Turning off my laptop and removing the power supply for 5-10 minutes before turning it back on.
     3)  Using the IP Config in Command Prompt
         ipconfig /flushdns
         ipconfig /registerdns
         ipconfig /release
         ipconfig /renew
     4) Using the NetSh reset in Command Prompt and restarting my laptop
         netsh int ip reset c:\resetlog.txt
         netsh winsock reset
         ipconfig /flushdns
         [restart laptop]
     5)  Configuring the TCP/IP in several settings
        Select Internet Protocol Version 4 (TCP/IPv4), and then click Properties.
        I have used the following settings:
           a) Obtain an DNS server address automatically
           b) OpenDNS
               208 67 222 222
               208 67 220 220
           c) Google DNS
               8 8 8 8
               8 8 4 4
     6) Updating the driver for my Intel Centrino(R) Advanced-N 6250 AGN and Intel Centrino(R) WIMAX 6250 from the Intel website previous having my laptop wiped clean in 2014.  It still did not resolve the issue.  My laptop
    manufacturer as not come up with an driver update for my adapter since 2010.  I haven't tried to update the adapter driver from Intel's website since having my laptop repaired due to the fact that Intel strongly recommending using the manufacturer's updates
    instead and frankly it didn't make much of a difference when I did it the first time.
     7) The last one I've tried as of today is going into Services and changing the start up type to automatic for the following:
           Computer Browser [changed from manual to automatic]
           DHCP Client [already set to automatic]
           DNS Client [already set to automatic]
           Network Connections [already set to automatic]
           Network Location Awareness [changed from manual to automatic]
           Remote Procedure Call (RPC) [already set to automatic]
           Server [already set to automatic]
           TCP/IP Netbios helper [already set to automatic]
           Workstation [already set to automatic]
    ...and I'm still having DNS issues.
    My only guessing are that my laptop came with a lemon adapter that needs to be replaced, some advanced setting(s) that I'm not aware off, or my firewall/anti-virus is interfering. I've used Symmantic Anti-virus and Firewall in the past and currently
    Avast Anti-Virus with Microsoft Network Firewall.  I've had DNS issues with both anti-virus/firewall set ups.
    Below are the results from the diagnostics and tests that I've ran.

  • External DNS server not replicating records to secondary after migration from 2003 to 2012

    Hi
    I have a query relating to 2012 Server and DNS.
    Last week we de-commissioned our primary external DNS server (Windows 2003 Server) and moved the role over to a new Windows 2012 server.
    Since this point replication to our secondary server (3rd party hosted) does not seem to occur and our DNS records seem to have expired on the secondary server as we cannot look these up via nslookup.
    I cannot see any failures in the event log of the server; I have checked our external firewall logs and nothing is being blocked inbound/ outbound as far as I can see. And the server’s local firewall has been disabled.
    The server is a standalone server in a workgroup with a standard filebased primary zone, with no AD integration and recursion disabled.
    When I created the zone I copied the .dns file from the old server and selected this in the interface during the creation of the zone on the new server.  The new server has the same internal and external IP as the old server and the old server is off-line.
    I have also manually increased the serial number of the zone and still no joy.
    One thing that I have noticed is when I open the zones properties/Name Servers and click edit on the external nameserver I get the infamous "The server with this IP address is not authoritative for the required zone" error.
    Any help Would be appreciated, thanks in advance

    Nice to hear that you are close in finding the problem. So in short:
    You have enabled Zone transfers in DNS management console for the applicable zone
    You have verified that your DNS is listening to the correct interfaces
    You have enabled firewall rules to accept TCP and UDP traffic to port 53
    You have checked if "BIND secondaries" option is applicable to your case
    You have initiated a zone transfer from the secondary server

    Hi -- I am not terribly experienced with DNS and I am running into an issue that I can't seem to resolve. My company.com DNS information is hosted by an outside ISP for email, web, etc... but I have configured an A record there to point to the public IP to my mac os x server (server.company.com).
    We have a cisco router configured with one to one NAT from the public IP to the internal IP for our server in a 192.168.15.x subnet. The same router is running DHCP and and NAT on that subnet under a different public IP provided by our ISP.
    Our server is running DNS with recursion and has a "company.private" zone set up for internal services and machine names. Thus, the server is accessible via "server.company.com" from the outside and "server.company.private" from the private LAN.
    The problem is that I would like to be able to access some services simply via "server.company.com" both inside and outside the private network. Now, accessing the "server.company.com" services from the private lan does not work because the name resolves to the external IP and the external IP cannot be used internally due to NAT.
    Is there a way to configure my internal DNS server to respond with the appropriate private address when receiving a query only to "server.company.com" and forward requests on for anything else on "company.com"?
    I know that I could manually duplicate all entries for our domain from my ISP and host the same entries for internal clients, but it would be much easier to only have our server handle requests for itself. The server is running OS X Server 10.4.11.
    Thanks

    Is there a way to configure my internal DNS server to respond with the appropriate private address when receiving a query only to "server.company.com" and forward requests on for anything else on "company.com"?
    Ordinarily, no. Once your server thinks it is responsible for a zone (e.g. company.com) then it will answer all queries for that domain and never pass them upstream. Therefore you'd have to replicate all the zone data, including all the public records, and maintain them both.
    The one possible exception to this (I haven't tried) is to create a zone for server.company.com that has your internal address. In theory (like I said, I haven't tried this), the server should respond to 'server.company.com' lookups with its own zone data and defer all other lookups (including other company.com names since they're not in a zone it controls). Might be worth trying.

  • How do I have a cRIO register its IP address with the DNS server, clearing any previous entries?

    I've run into a problem when I try to move a cRIO-9073 from one network segment to another (say 10.1.33.x to 10.1.36.x):  The old IP address remains registered on our DNS server, so trying to access the cRIO by its DNS name fails as the DNS server tells my PC to look for the old IP address.
    When I search the DNS server from my PC using "NSLOOKUP" with the old IP address, it finds the DNS name of the device.  If I repeat the search with the new IP address (MAX finds the device with its new address, but I hate to have users use MAX to find it), it again returns the DNS name, so it appears the DNS name is registered under two IP addresses on our DNS server.  I've also repeatedly tried to flush my PC's DNS cache using command "IPCONFIG /FLUSHDNS", but it still tries the old IP address.  I also see in MAX that the cRIO is using the same DNS server my PC uses.
    Our IT people say that I have to tell the device to re-register its DNS name.  They told me a command to do it from Windows (command "ipconfig /registerdns"), but obviously this is VxWorks on the cRIO.  Is there a command to do this on the cRIO or a setting in the "NI-RT.INI" file I can change?  I honestly don't think this is the issue (as it successfully registered the new IP address under its name), but I want to try it if it's possible.
    Thanks!
    Erik
    ps - Our IT dept. won't let me use static IPs unless I get them assigned by both their MAC address AND the network jack they're connected to, so that's out.

    Normally this is actually a function of your DNS server. It needs to perform a periodic flush of stale records. You can check the RFC for the DNS protocol and build the necessary packet yourself.

  • New HP LaserJet Pro MFP M127fw network connection impacts DNS server of my ISP

    Hi,
    i am not well with english, so please sorry
    I have deliverd new HP LaserJet Pro M127fw to my client who have 3 PC-s Win7 64bit, one 4 port switch, and one TP-link ISDN modem-router.
    I have installed the printer over network and everything is done well. Printer is working in printing/scanning/fax/ and copy.
    In few hurs local ISP has called and said that his DNS server is impacted by something from local LAN. After investigating, i have fount that printer is doing impact to DNS of ISP. When i remove LAN cable from printer, everything is fine with network
    I have installed new frimware from HP.com. also I have change Admin pass. The new up to date software is installed.
    Still have problem, and no solution. For now printer is working with USB connection, but that is not a option.
    HP please help!

    Hi @ITMračunari ,
    I see that you are having issues with the printer connected by a Ethernet cable to the network, the printer is impacting the DNS of ISP. I would like to help.
    Turn the IPv6 off on the printer to see if that will help.
    Go to Setup, Network Setup, Network Services, IPv6 and turn it off.
    This is a Consumer product and has been proving to work with a direct connection to a router.
    I noticed in your post that you are also using a switch, which could possible cause other conflicts.
    Hope this helps.
    Have a nice day!
    Thank You.

  • Airport Extreme invalid IP address, no DNS server

    Hardware: Motorola SURFboard SB6141, Airport Extreme A1408
    I recently set up a new internet service with Cox, plugged in the SB6141 and A1408 and everything set up perfectly, solid green light and wireless was flawless. However, electricity to my house had to be reset, and when the power came back on the green light on the Airport Extreme started to flashing amber. I did several hard/factory resets of the Airport Extreme as well as unplugging the modem and leaving everything unplugged for several minutes and then plugging everything back in. No matter what combination of things I try to do, the Airport Utility always tells me the same 2 errors: invalid IP address and no DNS server. Why was the Airport Extreme able to automatically set up the first time, but not now? Any ideas of what I can do? Thanks!

    I have also looked through other threads about this same problem, but none of the solutions (e.g. posts by Tesserax, followed to the letter) so far have worked.
    Here are other things I have tried:
    1. Called Cox to have them reset my modem, internet works through Ethernet directly from the modem
    2. Downgraded AEBS firmware to 7.6.1 (oddly enough, now I cannot for the life of me update the firmware back to 7.6.4, always says cannot connect to update server)
    I ran through the various solutions from this thread: "No DNS servers" and "Internet connection" problems with Comcast?
    Still getting that pesky blinking amber light.

  • 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.

  • Can't connect to mail server - DNS Server settings?

    Hello:
    Let me preface this question by saying that computer networking is not my strong suit.
    Last week I moved our web hosting from our ISP to Lunarpages; our domain is marshall-arts.net. I set up some POP email accounts on our new mail servers and was able to successfully send and receive email wirelessly using our G4 ibook. However, none of our networked desktop systems could connect to our new mail server, although they could connect to our ISP's mail server; they also have no problem connecting to the web. The mail server and user names were identical between the desktop systems and the ibook. But upon closer examination of the TCP/IP settings of the ibook I found that the ibook had 209.253.113.10 entered into the DNS Servers (optional) field. That field was blank in the desktop systems. Once I entered that address into the DNS Servers field on the desktop systems they had no problem connecting to our Lunarpages mail servers.
    Here's our setup, as best as I can describe it:
    We have an AirPort Extreme connected to our DSL router. It's connected via ethernet, configured manually with a static IP, router and DNS server addresses provided by our ISP. It's set to distribute IP addresses with the AirPort client computers sharing a single IP address using DHCP and NAT (10.0.1.1. addressing). It's connected via ethernet to a Linksys gigabit ethernet switch to which we have connected three desktop Macs running OS 10.3.x and 10.4.x.
    The TCP/IP of the three desktop systems and the ibook are configured Using DHCP.
    As I wrote above, only the ibook had an address entered into the DNS Servers field, 209.253.113.10. This doesn't correspond to anything our ISP provided (those addresses are entered in the AirPort Extreme.) I have no idea where it came from.
    So I have two questions:
    Would that address have been generated automatically while setting up the AirPort connection on the ibook?
    Why would that supposedly optional DNS Server address be required for me to connect to our new mail servers (but not our old ISP mail servers)?
    Thank you.

  • "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.
