  • DNS cache-on-demand server in Win7

    - by Andrew Heath
    I live in a country that enjoys manipulating DNS entries for fun and profit. For various reasons, I cannot surf with a VPN running 100% of the time. Because some sites are only blocked via DNS spoofing, it would be very handy if I could run a local DNS server that I could update on command during active VPN sessions. Is this granularity possible on Win7? Most of the DNS server related posts on SU are regarding the more config-friendly Linux platforms...

  • Windows 7 DNS stuck at manual

    - by Populus
    I am using the google dns servers most of the time, but for one particular wifi connection it blocks that ip so I have to revert back to automatically choosing DNS... The problem now is everytime I connect to this network, I have to change it back to automatic DNS manually (ironically), it's stuck on using the google DNS by default... It's a trivial problem, but would be fab if someone can help me out here...

  • DNS error only in IE

    - by Le_Quack
    Our Intranet page has stopped working on some machines/some user accounts. The error I am getting points to a DNS issue but If I ping the site from the command line the it responds fine. The error I'm gettting on IE is Error: The web filter could not find the address for the requested site Why are you seeing this: The system is unable too determine the IP address of intranet.example.com I'm not quite sure why it mentions the web filter as there is a proxy exception for the intranet page and if I run a trace route it doesn't go via the web proxy (filtering system). Finally it isn't affecting everyone, just random users, also it doesn't affect the random users on all the client machines they use. I have one user where it happens on any client they log onto where most its just certian clients. It's even "fixed" itself for a few peoples. EDIT: hey Mikey thanks for the fast response. Proxies are correct and automatic configuration is off (both via GPO)

  • Is it possible to set a SRV record with xname.org

    - by Emilien
    According to XName's (not up-to-date) ChangeLog Thu Oct 19 2006 Yann Hirou ([email protected]) Adding SRV records - including modification of dns_records it appears to be possible to set a SRV record for one of your zones. However, I just can't find a way to do this in the UI. I've contacted Yann Hirou, but didn't receive any answer (he is either submerged by emails, or only responds to "paying supporters") It might be that the feature is available in the source code, but that the instance running on XName has not been updated (since 2006?) Has anyone using XName been able to set up such records? Otherwise I might be forced to switch to another free DNS service...

  • Split DNS clarification

    - by RidableCthulu
    I need some clarification if I understood this correctly. I've been reading about Active Directory and naming my domain, and the reason Microsoft didn't suggest using external public domain was DNS Split. If I understood correctly (and please correct me if I did) in this case I have two Domain Name Servers, both doing the same job, but one of them is internal (in my company i.e.) and the other is a public one. Did I misunderstand this and if I did could somebody explain this to me? I hope this question is not too broad for this site! Cheers.

  • Why should one have a secondary DNS server?

    - by Sam Levin
    I'm very confused. I basically understand how DNS works. Here's an example that helps illustrate what I'm having trouble understanding. Right now, I run a small web-server. I use my provider's DNS manager, so I don't have a DNS server hosted on the machine. Let's say for a second, that I don't use my host's DNS, and I decide to set up a DNS server on my server. Hypothetical scenario: my server (entire) server goes down - DNS included. Why do I need backup DNS? If the server is down, who cares if the DNS server is down too, considering that even if I had DNS up (it wasn't on the crashed server), it wouldn't be able to forward requests anyway since the server would be down? Is the point of having secondary DNS, to be able to change the IP addresses that your DNS server points to, so if your webserver was down, you could redirect traffic to a backup? How would you switch to the secondary provider, in the event that your main DNS provider becomes unavailable? Is a backup DNS system basically up all the time? How is it configured? Is it just an exact clone of the DNS server you would have on your server? Do they run simultaneously? Hopefully someone can see what I'm hung up on, and provide some guidance. Thanks

  • Domain Controller DNS Best Practice/Practical Considerations for Domain Controllers in Child Domains

    - by joeqwerty
    I'm setting up several child domains in an existing Active Directory forest and I'm looking for some conventional wisdom/best practice guidance for configuring both DNS client settings on the child domain controllers and for the DNS zone replication scope. Assuming a single domain controller in each domain and assuming that each DC is also the DNS server for the domain (for simplicity's sake) should the child domain controller point to itself for DNS only or should it point to some combination (primary VS. secondary) of itself and the DNS server in the parent or root domain? If a parentchildgrandchild domain hierarchy exists (with a contiguous DNS namespace) how should DNS be configured on the grandchild DC? Regarding the DNS zone replication scope, if storing each domain's DNS zone on all DNS servers in the domain then I'm assuming a DNS delegation from the parent to the child needs to exist and that a forwarder from the child to the parent needs to exist. With a parentchildgrandchild domain hierarchy then does each child forward to the direct parent for the direct parent's zone or to the root zone? Does the delegation occur at the direct parent zone or from the root zone? If storing all DNS zones on all DNS servers in the forest does it make the above questions regarding the replication scope moot? Does the replication scope have some bearing on the DNS client settings on each DC?

  • windows xp mode for windows 7 - save text input language settings

    - by Gero
    When I change the 'default language' in 'text services and input languages' in windows xp mode from EN-US to DE-DE the settings are reverted with the next logoff / reboot - EN-US is the default language again. Is there a way around this behaviour? I'm using the default 'XPMUser' in windows xp mode. I also checked 'turn off advanced text services' and disabled the language bar and windows xp remembers these settings - just not the default language..

  • Windows Server 2008, IIS7 and Windows Authentication

    - by Chalkey
    We currently have a development server set up which we are trying to test some Windows authentication ASP.NET code on. We have turned on Windows Authentication in IIS7 on Windows Server 2008 R2 fine, and it asks the user for a username and password as excepted, but the problem is it doesn't appear to accept any credentials. This code for example... Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Page.Title = "Home page for " + User.Identity.Name End Sub ...always returns an empty string. One theory we have is that we dont have Active Directory installed as of yet, we are just testing this by logging on via the machine name not a domain. Is this type of authentication only applicatable to domains (if so we can probably install Active Directory and some test accounts) - or is it possible to get the user identity when logging in using the machine name? Ideally we would like to be able to test this on our local machines (Windows 7 Pro) using our own accounts (again these aren't on a domain) and IIS but this has the same issue as our dev server. Thanks,

  • Windows Server 2008 (sp2) stops responding on network share requests from Windows Vista and 7 client

    - by Peter LaComb Jr.
    I have two Windows Server 2008 SP2 machines (TFS and TFSBUILD). Periodically, the TFSBUILD server shares (\TFSBUILD\ShareName or \TFSBUILD\C$) become unresponsive to requests from Windows Vista (Server 2008) and Windows 7 client requests. Windows XP machines are still able to connect. No events in the server log indicate any problem. A simple restart corrects the issue temporarily, but it always returns. No, it is not this http://support.microsoft.com/kb/976266 (we aren't using that software). All anti-virus software has been disabled, firewall is disabled by policy. No other network activity is affected. Any help would be greatly appreciated.

  • Install windows XP alongside Windows 8

    - by user01
    I have a 64 bit (AMD)CPU but it has 32 bit Windows 8 installed. Could I somehow trickily install another Windows XP 64 bit alongside to that ? I want to do this because I almost never use the Windows 8 apps & majorly use this machine for java development. So I would like to run a lightweight OS implementation. Additionally, With 64 bit version of Windows XP, I would be able to take advantage of my 64 bit CPU. So, how do I do it? (I hope there's some way to do this:)

  • Have a legitimate Windows 7 license and the Windows 7 key but don't have the DVD

    - by sonicboom
    I just booted up my 'old' PC that's been lying around for the last two years. I have Windows 7 on it and I'm looking to format the drive and do a fresh install of W7. I have the key for Windows 7 in a text file. However I don't have the Windows 7 DVD or image. So is there any way of burning off a Windows 7 DVD considering that its the operating system I'm currently using? If not...well I have a W7 key, will this key work with any W7 DVD or is it particular to the W7 image that came with the key?

  • DNS NAmeserver Aname and cname records

    - by David
    Hi - I am inexperienced in the configuration of DNS and have an issue with dominan hosting set up. I have two domains 'www.mydomain1.com' and 'www.mydomain2.com', with mydomain2 pointed at the same place as mydomain1. The domains were passed to me recently by the person who previoulsy controlled them. I have an account with fasthosts in the uk. When I accepted the domains I could not access the DNS settings and enquired with fasthosts as to why. The replied saying 'The delegate hosting option for both domains were enabled and this is the reason why you were unable to find the option to edit the advanced DNS records. I have now disabled the delegate hosting option so you can now edit the advanced DNS records for both domains in your account.' When i log into the fasthost control panel now i can access the DNS controls but both domains have no A Record of Cname record set up. I am concerned that fasthosts have blatted the previous Nameserver entries and set me up on theirs but not added any record. 'www.mydomain1.com' currently still works but 'www.mydomain2.com' does not find the site anymore. i am worried i will lose mydomain1 to as teh dns changes filter through the system. my webhosting is at 'xxx.xxx.xxx.xxx/mydomain1.com/' and this is where I want both domains to point. Any advice would be much appreciated. one thing which is confusing me is that because I am on a shared server I have to put 'xxx.xxx.xxx.xxx/mydomain1.com/' to get to my site rather than just 'xxx.xxx.xxx.xxx'. The form on fasthosts for the aname record only allows an IP to be entered - does it add the mydomain1.com/ onto the end itself? Thanks for any help given - I'm quite worried about this David

  • Test All Features of Windows Phone 7 On Your PC

    - by Matthew Guay
    Are you developer or just excited about the upcoming Windows Phone 7, and want to try it out now?  Thanks to free developer tools from Microsoft and a new unlocked emulator rom, you can try out most of the exciting features today from your PC. Last week we showed you how to try out Windows Phone 7 on your PC and get started developing for the upcoming new devices.  We noticed, however, that the emulator only contains Internet Explorer Mobile and some settings.  This is still interesting to play around with, but it wasn’t the full Windows Phone 7 experience. Some enterprising tweakers discovered that more applications were actually included in the emulator, but were simply hidden from users.  Developer Dan Ardelean then figured out how to re-enable these features, and released a tweaked emulator rom so everyone can try out all of the Windows Phone 7 features for themselves.  Here we’ll look at how you can run this new emulator image on your PC, and then look at some interesting features in Windows Phone 7. Editor Note: This modified emulator image is not official, and isn’t sanctioned by Microsoft. Use your own judgment when choosing to download and use the emulator. Setting Up Emulator Rom To test-drive Windows Phone 7 on your PC, you must first download and install the Windows Phone Developer Tools CTP (link below).  Follow the steps we showed you last week at: Try out Windows Phone 7 on your PC today.  Once it’s installed, go ahead and run the default emulator as we showed to make sure everything works ok. Once the Windows Phone Developer Tools are installed and running, download the new emulator rom from XDA Forums (link below).  This will be a zip file, so extract it first. Note where you save the file, as you will need the address in the next step. Now, to run our new emulator image, we need to open the emulator in command line and point to the new rom image.  To do this, browse to the correct directory, depending on whether you’re running the 32 bit or 64 bit version of Windows: 32 bit: C:\Program Files\Microsoft XDE\1.0\ 64 bit: C:\Program Files (x86)\Microsoft XDE\1.0\ Hold your Shift key down and right-click in the folder.  Choose Open Command Window here. At the command prompt, enter XDE.exe followed by the location of your new rom image.  Here, we downloaded the rom to our download folder, so at the command prompt we entered: XDE.exe C:\Users\Matthew\Downloads\WM70Full\WM70Full.bin The emulator loads … with the full Windows Phone 7 experience! To make it easier, let’s make a shortcut on our desktop to load the emulator with the new rom directly.  Right-click on your desktop (or any folder you want to create the shortcut in), select New, and then Shortcut. Now, in the box, we need to enter the path for the emulator followed by the location of our rom.  Both items must be in quotes.  So, in our test, we entered the following: 32 bit: “C:\Program Files\Microsoft XDE\1.0\” “C:\Users\Matthew\Downloads\WM70Full\WM70Full.bin” 64 bit: “C:\Program Files (x86)\Microsoft XDE\1.0\” “C:\Users\Matthew\Downloads\WM70Full\WM70Full.bin” Make sure to enter the correct location of the new emulator rom for your computer, and keep both items in separate quotes.  Click next when you’ve entered the location. Name the shortcut; we named it Windows Phone 7, but simply enter whatever you’d like.  Click Finish when you’re done. You should now have a nice Windows Phone icon and your fully functional shortcut!  Double-click it to run the Windows Phone 7 emulator as above. Features in the Unlocked Windows Phone 7 Emulator So let’s look at what you can do with this new emulator.  Almost everything you’ve seen in demos from the Mobile World Conference and Mix’10 are right here for you to play with.  Here’s the application menu, which you can access by clicking on the arrow on the top of the home screen, which shows how much stuff they’ve got in this!   And, of course, even the home screen itself shows much more activity than it did in the original emulator. Let’s check out some of these sections.  Here’s Zune running on Windows Phone 7, and the Zune Marketplace.  The animations are beautiful, so be sure to check this out yourself. The new picture hub is much nicer than any picture viewer included with Windows Mobile in the past…   Stay productive, and on schedule with the new Calendar. The XBOX hub gives us only a hint of things to come, and the links to games now are simply placeholders. Here’s a look at the Office hub.  This doesn’t show up on the homescreen right now, but you can access it in the applications menu.  Office obviously still has a lot of work left on it, but even at a glance here it looks like it includes a lot more functionality than Office Mobile in Windows Mobile 6. Here’s a look at each of the three apps: Word, Excel, and OneNote, and the formatting pallet in Office apps.   This emulator also includes a lot more settings than the default one, including settings for individual applications. You can even activate the screen lock, and try out the lift-to-peek-or-unlock feature… Finally, this version of Windows Phone 7 includes a very nice SystemInfo app with an advanced task manager.  We hope this is still available when the actual phones are released. Conclusion If you’re excited about the upcoming Windows Phone 7 series, or simply want to learn more about what’s coming, this is a great way to test it out.  With these exciting new hubs and applications, there’s something here for everyone.  Let us know what you like most about Windows Phone 7 and what your favorite app or hub is.

  • Reason for perpetual dynamic DNS updates?

    - by mad_vs
    I'm using dynamic DNS (the "adult" version from RFC 2136, not à la DynDNS), and for a while now I've been seeing my laptops with MacOS 10.6.x churning out updates about every 10 seconds. And seemingly redundant updates at that, as the IP is more or less stable (consumer broadband). I don't remember seeing that frequency in the (distant...) past. The lowest time-to-live that MacOS pushes on the entries is 2 minutes, so I have no clue what's going on. ... Jan 12 13:17:18 lambda named[18683]: info: client 84.208.X.X#48715: updating zone 'dynamic.foldr.org/IN': deleting rrset at 'rCosinus._afpovertcp._tcp.dynamic.foldr.org' SRV Jan 12 13:17:18 lambda named[18683]: info: client 84.208.X.X#48715: updating zone 'dynamic.foldr.org/IN': adding an RR at 'rCosinus._afpovertcp._tcp.dynamic.foldr.org' SRV Jan 12 13:17:26 lambda named[18683]: info: client 84.208.X.X#48715: updating zone 'dynamic.foldr.org/IN': deleting rrset at 'rcosinus.dynamic.foldr.org' AAAA ... Additionally, I can't find out what triggers the updates on the laptop-side. Is this a known problem, and how would I go about debugging it? One of the machines is freshly purchased and installed. The only "major" change was installation of the Miredo client for IPv6/Teredo, but even disabling it didn't make a change (except that AAAA records are no longer published).

  • Find DNS server automatically

    - by jdickson
    I've got a Windows 2012 server set up as a domain controller and DNS server in my basement. On my laptop, if I set it to use the IP address of my server as the DNS server, then it works as expected. The problem with that is that I use my laptop outside my home network and I need to switch it back to automatic. Setup is like this: ISP Router running DD-WRT Win 2012 DC/DNS and other network computers How can I have my laptop find the DNS server automatically instead of using my ISP's DNS servers?

  • Very long DNS lookups inside my network

    - by Nuno Cordeiro
    Ever since I installed DD-WRT (v24-sp2 08/07/10 std-usb-ftp) on my router (RT-N16), my browsing got substantially slower. Using FirePHP I figured out that it's being caused by VERY long DNS lookups (~30 seconds). When the domain name was very recently accessed then speed is very good. I tried changing DNS on the computer and I tried messing around with the options on DD-WRT. I have tried to configure the router with Google DNS and/or OpenDNS. My current DNS output after using ipconfig -all is: 192.168.1.1 208.67.220.220 8.8.8.8 208.67.222.222 Can someone help me debug and solve this problem? I'd like to snoop the requests themselves. How can I know which DNS requests are being sent and which are failing/succeeding? Note: I don't expect this to be relevant but my router is connected to the internet through an ONT.

  • Sort order in Windows Explorer

    - by Haim H.
    The behaviour described below occurs on Windows-7 systems and on Windows XP. We operate in a dual-language environment - English and Hebrew. When in Windows Explorer we sort files by name, the order in which they are listed is not what we would expect. Here is a list of file names as sorted by Windows Explorer (all of the files have a .pdf suffix): 1G110033H-PP 19C050G-PP-ORB 19C050H-PPRM 19C100H-PPRM 19C-MBPS-PP 19C-MBPS-PP-1 29AAC050-PP 29AAC100-PP 29AAC100-PPUL 29B004064-PP 101AC050-PP 101AC100-PP 101B100-PPE 1091003G-PPFSUL 10108033G-PPSA 10125033H-PPM It looks to me that first the items are sorted according to the position of the first alphabetic character in the name, and then, within those groups, they are sorted in "normal" alpha-numeric order. That is, all the files with an alpha character in the first position are on top of the list, followed by those with the first alpha character in the second position, followed by those with the first alpha character in the third position, and so on. An alternate way of looking at this is that, in a file name composed of numbers and letters, the sort treats the first group of numbers in the name as the major sort node, with the rest of the name being the secondary sort node. Now that I understand the sequencing logic, it's not a big problem, but I was wondering why this happens?

  • BIND split-view DNS config problem

    - by organicveggie
    We have two DNS servers: one external server controlled by our ISP and one internal server controlled by us. I'd like internal requests for foo.example.com to map to 192.168.100.5 and external requests continue to map to 1.2.3.4, so I'm trying to configure a view in bind. Unfortunately, bind fails when I attempt to reload the configuration. I'm sure I'm missing something simple, but I can't figure out what it is. options { directory "/var/cache/bind"; forwarders { 8.8.8.8; 8.8.4.4; }; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; zone "." { type hint; file "/etc/bind/db.root"; }; zone "localhost" { type master; file "/etc/bind/db.local"; }; zone "127.in-addr.arpa" { type master; file "/etc/bind/db.127"; }; zone "0.in-addr.arpa" { type master; file "/etc/bind/db.0"; }; zone "255.in-addr.arpa" { type master; file "/etc/bind/db.255"; }; view "internal" { zone "example.com" { type master; notify no; file "/etc/bind/db.example.com"; }; }; zone "example.corp" { type master; file "/etc/bind/db.example.corp"; }; zone "100.168.192.in-addr.arpa" { type master; notify no; file "/etc/bind/db.192"; }; I have excluded the entries in the view for allow-recursion and recursion in an attempt to simplify the configuration. If I remove the view and just load the example.com zone directly, it works fine. Any advice on what I might be missing?

  • Weird DNS bug - external server resolves to internal IP

    - by emilecantin
    I have a server that is hosted by my university. I have root access, but no control over network setup, firewall, etc. This server's DNS resolves to an internal IP here on campus (10.x.x.x), and an external IP outside campus. I also have a few servers hosted at Amazon, and they mostly work well. However, one of them started to resolve the university server by its internal IP address. This causes problems, as 10.x.x.x on Amazon EC2 is someone else. I have connected to the Amazon server with SSH agent forwarding a few times in the past, to access a Git repository on the university server. Any idea what could cause this?

  • Windows Azure: Announcing Support for Windows Server 2012 R2 + Some Nice Price Cuts

    - by ScottGu
    Today we released some great updates to Windows Azure: Virtual Machines: Support for Windows Server 2012 R2 Cloud Services: Support for Windows Server 2012 R2 and .NET 4.5.1 Windows Azure Pack: Use Windows Azure features on-premises using Windows Server 2012 R2 Price Cuts: Up to 22% Price Reduction on Memory-Intensive Instances Below are more details about each of the improvements: Virtual Machines: Support for Windows Server 2012 R2 This morning we announced the release of Windows Server 2012 R2 – which is a fantastic update to Windows Server and includes a ton of great enhancements. This morning we are also excited to announce that the general availability image of Windows Server 2012 RC is now supported on Windows Azure.  Windows Azure is the first cloud provider to offer the final release of Windows Server 2012 R2, and it is incredibly easy to launch your own Windows Server 2012 R2 instance with it. To create a new Windows Server 2012 R2 instance simply choose New->Compute->Virtual Machine within the Windows Azure Management Portal.  You can select the “Windows Server 2012 R2” image and create a new Virtual Machine using the “Quick Create” option: Or alternatively click the “From Gallery” option if you want to customize even more configuration options (endpoints, remote powershell, availability set, etc): Creating and instantiating a new Virtual Machine on Windows Azure is very fast.  In fact, the Windows Server 2012 R2 image now deploys and runs 30% faster than previous versions of Windows Server. Once the VM is deployed you can drill into it to track its health and manage its settings: Clicking the “Connect” button allows you to remote desktop into the VM – at which point you can customize and manage it as a full administrator however you want: If you haven’t tried Windows Server 2012 R2 yet – give it a try with Windows Azure.  There is no easier way to get an instance of it up and running! Cloud Services: Support for using Windows Server 2012 R2 with Web and Worker Roles Today’s Windows Azure release also allows you to now use Windows Server 2012 R2 and .NET 4.5.1 within Web and Worker Roles within Cloud Service based applications.  Enabling this is easy.  You can configure existing existing Cloud Service application to use Windows Server 2012 R2 by updating your Cloud Service Configuration File (.cscfg) to use the new “OS Family 4” setting: Or alternatively you can use the Windows Azure Management Portal to update cloud services that are already deployed on Windows Azure.  Simply choose the configure tab on them and select Windows Server 2012 R2 in the Operating System Family dropdown: The approaches above enable you to immediately take advantage of Windows Server 2012 R2 and .NET 4.5.1 and all the great features they provide. Windows Azure Pack: Use Windows Azure features on Windows Server 2012 R2 Today we also made generally available the Windows Azure Pack, which is a free download that enables you to run Windows Azure Technology within your own datacenter, an on-premises private cloud environment, or with one of our service provider/hosting partners who run Windows Server. Windows Azure Pack enables you to use a management portal that has the exact same UI as the Windows Azure Management Portal, and within which you can create and manage Virtual Machines, Web Sites, and Service Bus – all of which can run on Windows Server and System Center.  The services provided with the Windows Azure Pack are consistent with the services offered within our Windows Azure public cloud offering.  This consistency enables organizations and developers to build applications and solutions that can run in any hosting environment – and which use the same development and management approach.  The end result is an offering with incredible flexibility. You can learn more about Windows Azure Pack and download/deploy it today here. Price Cuts: Up to 22% Reduction on Memory Intensive Instances Today we are also reducing prices by up to 22% on our memory-intensive VM instances (specifically our A5, A6, and A7 instances).  These price reductions apply to both Windows and Linux VM instances, as well as for Cloud Service based applications: These price reductions will take effect in November, and will enable you to run applications that demand larger memory (such as SharePoint, Databases, in-memory analytics, etc) even more cost effectively. Summary Today’s release enables you to start using Windows Server 2012 R2 within Windows Azure immediately, and take advantage of our Cloud OS vision both within our datacenters – and using the Windows Azure Pack within both your existing datacenters and those of our partners. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • DNS lookups failing somewhere between firewall and router

    - by TessellatingHeckler
    we have a setup of ADSL line - Cisco 837 ADSL router - Zyxel ZyWall 35 firewall/NAT - Switch == Intel load balanced NICS in a server. It has been fine for years, suddenly DNS resolution stopped working on the server. No changes that I know of, so I can't work backwards from there. It was configured with the ISP's DNS servers, neither network device does DNS relaying. Wireshark shows the request go out but nothing comes back. The server networking stack seems OK though, because if we query an internal DNS server on a remote site, that works. I can logon to the Cisco, and DNS resolves OK from the command line. I can logon to the ZyWall, and DNS does not resolve from the command line. So the problem seems to be the firewall, patch cable or router, yes? On the router: interface Ethernet0 ip address aaa.bbb.ccc.ddd 255.255.255.ddd ip tcp adjust-mss 1450 hold-queue 100 out On the firewall: DNS server set to 8.8.8.8 (Google's), DNS traffic allowed LAN-WAN. What else should I look for? Update: Following This guide I've got traffic logging on the Cisco. I have also got access to a public DNS server which I can run tcpdump on to see things from the other side. And as per the below comments, I've tested with Dig and see that DNS over TCP works, and over UDP does not. Currently: DNS request from the server using TCP shows up in the firewall log, and in the Cisco log, and in tcpdump on the DNS server, the answer comes back, it works fine. DNS request from the server using UDP shows up in the firewall log, and in the Cisco log, does NOT show in tcpdump on the DNS server, times out. DNS request from the cisco (using UDP) does show up in tcpdump on the DNS server, answer received, works fine. Ping requests from the server and the cisco to the DNS server show up in tcpdump on the DNS server. DNS request from the server using UDP does show up on the firewall. Summary: TCP seems fine throughought. UDP works over the ADSL and to the Cisco, and it works from the server to the Cisco, but it doesn't cross the Cisco properly, it seems. I did see the Cisco showing as connected at 10Mb/full-duplex internally, and the firewall showing as 100Mb/full-duplex externally. I have forced the firewall to 10Mb and rebooted both devices. That seemed to help get UDP traffic (server-firewall-cisco) instead of (server-firewall), but did not fix it. Update: Sanitized Cisco config: version 12.2 no service pad service timestamps debug datetime msec service timestamps log datetime msec service password-encryption ! hostname cisco ! logging queue-limit 100 enable secret 5 {password} enable password 7 {password} ! ip subnet-zero ip domain name example.org ip name-server {nameserver_IP} ! ! ip audit notify log ip audit po max-events 100 no ftp-server write-enable ! interface Ethernet0 ip address {Inside_public_IP} 255.255.255.248 ip tcp adjust-mss 1460 hold-queue 100 out ! interface ATM0 no ip address no atm ilmi-keepalive pvc 0/38 encapsulation aal5mux ppp dialer dialer pool-member 1 ! dsl operating-mode auto ! interface Dialer1 ip unnumbered Ethernet0 encapsulation ppp dialer pool 1 dialer idle-timeout 0 dialer persistent no cdp enable ppp chap hostname {ADSL_Username} ppp chap password 7 {ADSL_Password} ! ip classless ip route 0.0.0.0 0.0.0.0 Dialer1 no ip http server no ip http secure-server ! access-list 23 permit {IP} dialer-list 1 protocol ip permit no cdp run snmp-server enable traps tty ! {con, vty} end
