  • "Recursive" Wildcard DNS for Amazon Route 53

    - by Brian
    The title of the question might be misleading because I'm not an expert and I'm trying to learn the proper terminology. That being said, I'm wondering if it's possible to setup a wildcard DNS record for any number of dot separation in domain names and have them all point to the network root. This is for WordPress multisite, users will have the option of choosing a mapped domain name, I want to configure my DNS so that both mysite.co.uk.network.com and mysite.com.network.com are valid (I realize this is a but ugly, but WordPress multisite requires that each site have a unique site_url and I'd prefer to preserve the period-delimited appearance if it's possible).

  • Setting up dynamic DNS for linked router

    - by cherrun
    I have a 'main' router that receives the internet signal from the ISP and another one in my room, connected with a cable. The main router is running its original firmware and is very limited in its features, unfortunately I can not change this router, since my phone company has some hardcoded stuff in there and the internet will only work with this router. My second router is running DD-WRT firmware. Now I need to set up dynamic DNS, so I can access my NAS machine remotely, which is connected to the second router. As mentioned, this can't be done with the main router, due to its limited features. DHCP is turned off on the second router, since it gets its IP from the main one. Is there a possibility to set up dynamic DNS on the second router, without changing any (or much) on the main router? Maybe as a side note: I live in Germany, don't know if the set up of the routers are different in other countries.

  • DNS PTR record when domain on shared IP address

    - by Marco Demaio
    Hello, I own a typical shared IP hosting plan and domain. I can modify the DNS of the domain from the control panel. The mailserver shares the same IP address, so my typical DNS config is: www.mydomain.com A -> IP mydomain.com A -> IP ftp.mydomain.com A -> IP mail.mydomain.com A -> IP mydomain.com MX(10) -> IP I read some Q&A on this site where they suggest to add PTR record mainly for mailserver. I would like to add PTR record to my domain, I have got two questions: 1) can PTR record be added even if the hosting/mailserver are on a shared IP address? Or do I need a dedicated IP. 2) How do I setup PTR record, I mean does it look like A record: mydomain.com (PTR) -> myip

  • Hosted application, DNS server setup?

    - by Ward Loockx
    Currently I'm allowing users to have an hosted application. Currently they have to point A-records to our servers (sometimes this is to hard or get's messy). I've seen other players using 2 dns servers, so that the user only needs to change these. I'm willing to implement this, but a lot of questions come up. What should I use for this? Can I use bind? The records need to be generated from a mysql database What type of servers do I need? Is a DNS server taking a lot of load? Currently having around 80K daily visitors. Thanks!

  • Is DHCP required on a Win2003 secondary DNS server?

    - by Mark
    We have a secondary DNS server and we've been noticing that the DNS.exe process is getting rather large. (Like, rebooting the server large) I read something somewhere that 2k3 has two relevant memory leak issues, one is the DNS (supposedly fixed in 2007), and another for DHCP. DHCP is running on this server, but I don't see why. Hence my question. Is the DHCP service required for (secondary) DNS to function? Server has: 24 cores (X5650), 8GB RAM

  • Using a secondary DNS when lookup fails in primary? [migrated]

    - by Huckle
    I use a VPN to connect my development machine to my school's CS dept. The development machine is Ubuntu as we do C programming in Unix. I used vpnc to do that. The school uses some DNS entries that only resolve on their DNS servers, i.e., internalserver.csdept.school.edu I am normally attached to the VPN whenever booted for convenience. However I noticed the other day that when I disconnect the VPN all my DNS queries fail. This obviously means that vpnc set up the school's DNS to be used. However I'd rather not use their DNS all the time (tracking and privacy and whatnot). Is there a way I can restore my ISP's DNS and then if the lookup fails, have it use my school's DNS?

  • Windows Azure: Backup Services Release, Hyper-V Recovery Manager, VM Enhancements, Enhanced Enterprise Management Support

    - by ScottGu
    This morning we released a huge set of updates to Windows Azure.  These new capabilities include: Backup Services: General Availability of Windows Azure Backup Services Hyper-V Recovery Manager: Public preview of Windows Azure Hyper-V Recovery Manager Virtual Machines: Delete Attached Disks, Availability Set Warnings, SQL AlwaysOn Configuration Active Directory: Securely manage hundreds of SaaS applications Enterprise Management: Use Active Directory to Better Manage Windows Azure Windows Azure SDK 2.2: A massive update of our SDK + Visual Studio tooling support All of these improvements are now available to use immediately.  Below are more details about them. Backup Service: General Availability Release of Windows Azure Backup Today we are releasing Windows Azure Backup Service as a general availability service.  This release is now live in production, backed by an enterprise SLA, supported by Microsoft Support, and is ready to use for production scenarios. Windows Azure Backup is a cloud based backup solution for Windows Server which allows files and folders to be backed up and recovered from the cloud, and provides off-site protection against data loss. The service provides IT administrators and developers with the option to back up and protect critical data in an easily recoverable way from any location with no upfront hardware cost. Windows Azure Backup is built on the Windows Azure platform and uses Windows Azure blob storage for storing customer data. Windows Server uses the downloadable Windows Azure Backup Agent to transfer file and folder data securely and efficiently to the Windows Azure Backup Service. Along with providing cloud backup for Windows Server, Windows Azure Backup Service also provides capability to backup data from System Center Data Protection Manager and Windows Server Essentials, to the cloud. All data is encrypted onsite before it is sent to the cloud, and customers retain and manage the encryption key (meaning the data is stored entirely secured and can’t be decrypted by anyone but yourself). Getting Started To get started with the Windows Azure Backup Service, create a new Backup Vault within the Windows Azure Management Portal.  Click New->Data Services->Recovery Services->Backup Vault to do this: Once the backup vault is created you’ll be presented with a simple tutorial that will help guide you on how to register your Windows Servers with it: Once the servers you want to backup are registered, you can use the appropriate local management interface (such as the Microsoft Management Console snap-in, System Center Data Protection Manager Console, or Windows Server Essentials Dashboard) to configure the scheduled backups and to optionally initiate recoveries. You can follow these tutorials to learn more about how to do this: Tutorial: Schedule Backups Using the Windows Azure Backup Agent This tutorial helps you with setting up a backup schedule for your registered Windows Servers. Additionally, it also explains how to use Windows PowerShell cmdlets to set up a custom backup schedule. Tutorial: Recover Files and Folders Using the Windows Azure Backup Agent This tutorial helps you with recovering data from a backup. Additionally, it also explains how to use Windows PowerShell cmdlets to do the same tasks. Below are some of the key benefits the Windows Azure Backup Service provides: Simple configuration and management. Windows Azure Backup Service integrates with the familiar Windows Server Backup utility in Windows Server, the Data Protection Manager component in System Center and Windows Server Essentials, in order to provide a seamless backup and recovery experience to a local disk, or to the cloud. Block level incremental backups. The Windows Azure Backup Agent performs incremental backups by tracking file and block level changes and only transferring the changed blocks, hence reducing the storage and bandwidth utilization. Different point-in-time versions of the backups use storage efficiently by only storing the changes blocks between these versions. Data compression, encryption and throttling. The Windows Azure Backup Agent ensures that data is compressed and encrypted on the server before being sent to the Windows Azure Backup Service over the network. As a result, the Windows Azure Backup Service only stores encrypted data in the cloud storage. The encryption key is not available to the Windows Azure Backup Service, and as a result the data is never decrypted in the service. Also, users can setup throttling and configure how the Windows Azure Backup service utilizes the network bandwidth when backing up or restoring information. Data integrity is verified in the cloud. In addition to the secure backups, the backed up data is also automatically checked for integrity once the backup is done. As a result, any corruptions which may arise due to data transfer can be easily identified and are fixed automatically. Configurable retention policies for storing data in the cloud. The Windows Azure Backup Service accepts and implements retention policies to recycle backups that exceed the desired retention range, thereby meeting business policies and managing backup costs. Hyper-V Recovery Manager: Now Available in Public Preview I’m excited to also announce the public preview of a new Windows Azure Service – the Windows Azure Hyper-V Recovery Manager (HRM). Windows Azure Hyper-V Recovery Manager helps protect your business critical services by coordinating the replication and recovery of System Center Virtual Machine Manager 2012 SP1 and System Center Virtual Machine Manager 2012 R2 private clouds at a secondary location. With automated protection, asynchronous ongoing replication, and orderly recovery, the Hyper-V Recovery Manager service can help you implement Disaster Recovery and restore important services accurately, consistently, and with minimal downtime. Application data in an Hyper-V Recovery Manager scenarios always travels on your on-premise replication channel. Only metadata (such as names of logical clouds, virtual machines, networks etc.) that is needed for orchestration is sent to Azure. All traffic sent to/from Azure is encrypted. You can begin using Windows Azure Hyper-V Recovery today by clicking New->Data Services->Recovery Services->Hyper-V Recovery Manager within the Windows Azure Management Portal.  You can read more about Windows Azure Hyper-V Recovery Manager in Brad Anderson’s 9-part series, Transform the datacenter. To learn more about setting up Hyper-V Recovery Manager follow our detailed step-by-step guide. Virtual Machines: Delete Attached Disks, Availability Set Warnings, SQL AlwaysOn Today’s Windows Azure release includes a number of nice updates to Windows Azure Virtual Machines.  These improvements include: Ability to Delete both VM Instances + Attached Disks in One Operation Prior to today’s release, when you deleted VMs within Windows Azure we would delete the VM instance – but not delete the drives attached to the VM.  You had to manually delete these yourself from the storage account.  With today’s update we’ve added a convenience option that now allows you to either retain or delete the attached disks when you delete the VM:   We’ve also added the ability to delete a cloud service, its deployments, and its role instances with a single action. This can either be a cloud service that has production and staging deployments with web and worker roles, or a cloud service that contains virtual machines.  To do this, simply select the Cloud Service within the Windows Azure Management Portal and click the “Delete” button: Warnings on Availability Sets with Only One Virtual Machine In Them One of the nice features that Windows Azure Virtual Machines supports is the concept of “Availability Sets”.  An “availability set” allows you to define a tier/role (e.g. webfrontends, databaseservers, etc) that you can map Virtual Machines into – and when you do this Windows Azure separates them across fault domains and ensures that at least one of them is always available during servicing operations.  This enables you to deploy applications in a high availability way. One issue we’ve seen some customers run into is where they define an availability set, but then forget to map more than one VM into it (which defeats the purpose of having an availability set).  With today’s release we now display a warning in the Windows Azure Management Portal if you have only one virtual machine deployed in an availability set to help highlight this: You can learn more about configuring the availability of your virtual machines here. Configuring SQL Server Always On SQL Server Always On is a great feature that you can use with Windows Azure to enable high availability and DR scenarios with SQL Server. Today’s Windows Azure release makes it even easier to configure SQL Server Always On by enabling “Direct Server Return” endpoints to be configured and managed within the Windows Azure Management Portal.  Previously, setting this up required using PowerShell to complete the endpoint configuration.  Starting today you can enable this simply by checking the “Direct Server Return” checkbox: You can learn more about how to use direct server return for SQL Server AlwaysOn availability groups here. Active Directory: Application Access Enhancements This summer we released our initial preview of our Application Access Enhancements for Windows Azure Active Directory.  This service enables you to securely implement single-sign-on (SSO) support against SaaS applications (including Office 365, SalesForce, Workday, Box, Google Apps, GitHub, etc) as well as LOB based applications (including ones built with the new Windows Azure AD support we shipped last week with ASP.NET and VS 2013). Since the initial preview we’ve enhanced our SAML federation capabilities, integrated our new password vaulting system, and shipped multi-factor authentication support. We've also turned on our outbound identity provisioning system and have it working with hundreds of additional SaaS Applications: Earlier this month we published an update on dates and pricing for when the service will be released in general availability form.  In this blog post we announced our intention to release the service in general availability form by the end of the year.  We also announced that the below features would be available in a free tier with it: SSO to every SaaS app we integrate with – Users can Single Sign On to any app we are integrated with at no charge. This includes all the top SAAS Apps and every app in our application gallery whether they use federation or password vaulting. Application access assignment and removal – IT Admins can assign access privileges to web applications to the users in their active directory assuring that every employee has access to the SAAS Apps they need. And when a user leaves the company or changes jobs, the admin can just as easily remove their access privileges assuring data security and minimizing IP loss User provisioning (and de-provisioning) – IT admins will be able to automatically provision users in 3rd party SaaS applications like Box, Salesforce.com, GoToMeeting, DropBox and others. We are working with key partners in the ecosystem to establish these connections, meaning you no longer have to continually update user records in multiple systems. Security and auditing reports – Security is a key priority for us. With the free version of these enhancements you'll get access to our standard set of access reports giving you visibility into which users are using which applications, when they were using them and where they are using them from. In addition, we'll alert you to un-usual usage patterns for instance when a user logs in from multiple locations at the same time. Our Application Access Panel – Users are logging in from every type of devices including Windows, iOS, & Android. Not all of these devices handle authentication in the same manner but the user doesn't care. They need to access their apps from the devices they love. Our Application Access Panel will support the ability for users to access access and launch their apps from any device and anywhere. You can learn more about our plans for application management with Windows Azure Active Directory here.  Try out the preview and start using it today. Enterprise Management: Use Active Directory to Better Manage Windows Azure Windows Azure Active Directory provides the ability to manage your organization in a directory which is hosted entirely in the cloud, or alternatively kept in sync with an on-premises Windows Server Active Directory solution (allowing you to seamlessly integrate with the directory you already have).  With today’s Windows Azure release we are integrating Windows Azure Active Directory even more within the core Windows Azure management experience, and enabling an even richer enterprise security offering.  Specifically: 1) All Windows Azure accounts now have a default Windows Azure Active Directory created for them.  You can create and map any users you want into this directory, and grant administrative rights to manage resources in Windows Azure to these users. 2) You can keep this directory entirely hosted in the cloud – or optionally sync it with your on-premises Windows Server Active Directory.  Both options are free.  The later approach is ideal for companies that wish to use their corporate user identities to sign-in and manage Windows Azure resources.  It also ensures that if an employee leaves an organization, his or her access control rights to the company’s Windows Azure resources are immediately revoked. 3) The Windows Azure Service Management APIs have been updated to support using Windows Azure Active Directory credentials to sign-in and perform management operations.  Prior to today’s release customers had to download and use management certificates (which were not scoped to individual users) to perform management operations.  We still support this management certificate approach (don’t worry – nothing will stop working).  But we think the new Windows Azure Active Directory authentication support enables an even easier and more secure way for customers to manage resources going forward.  4) The Windows Azure SDK 2.2 release (which is also shipping today) includes built-in support for the new Service Management APIs that authenticate with Windows Azure Active Directory, and now allow you to create and manage Windows Azure applications and resources directly within Visual Studio using your Active Directory credentials.  This, combined with updated PowerShell scripts that also support Active Directory, enables an end-to-end enterprise authentication story with Windows Azure. Below are some details on how all of this works: Subscriptions within a Directory As part of today’s update, we have associated all existing Window Azure accounts with a Windows Azure Active Directory (and created one for you if you don’t already have one). When you login to the Windows Azure Management Portal you’ll now see the directory name in the URI of the browser.  For example, in the screen-shot below you can see that I have a “scottgu” directory that my subscriptions are hosted within: Note that you can continue to use Microsoft Accounts (formerly known as Microsoft Live IDs) to sign-into Windows Azure.  These map just fine to a Windows Azure Active Directory – so there is no need to create new usernames that are specific to a directory if you don’t want to.  In the scenario above I’m actually logged in using my @hotmail.com based Microsoft ID which is now mapped to a “scottgu” active directory that was created for me.  By default everything will continue to work just like you used to before. Manage your Directory You can manage an Active Directory (including the one we now create for you by default) by clicking the “Active Directory” tab in the left-hand side of the portal.  This will list all of the directories in your account.  Clicking one the first time will display a getting started page that provides documentation and links to perform common tasks with it: You can use the built-in directory management support within the Windows Azure Management Portal to add/remove/manage users within the directory, enable multi-factor authentication, associate a custom domain (e.g. mycompanyname.com) with the directory, and/or rename the directory to whatever friendly name you want (just click the configure tab to do this).  You can also setup the directory to automatically sync with an on-premises Active Directory using the “Directory Integration” tab. Note that users within a directory by default do not have admin rights to login or manage Windows Azure based resources.  You still need to explicitly grant them co-admin permissions on a subscription for them to login or manage resources in Windows Azure.  You can do this by clicking the Settings tab on the left-hand side of the portal and then by clicking the administrators tab within it. Sign-In Integration within Visual Studio If you install the new Windows Azure SDK 2.2 release, you can now connect to Windows Azure from directly inside Visual Studio without having to download any management certificates.  You can now just right-click on the “Windows Azure” icon within the Server Explorer and choose the “Connect to Windows Azure” context menu option to do so: Doing this will prompt you to enter the email address of the username you wish to sign-in with (make sure this account is a user in your directory with co-admin rights on a subscription): You can use either a Microsoft Account (e.g. Windows Live ID) or an Active Directory based Organizational account as the email.  The dialog will update with an appropriate login prompt depending on which type of email address you enter: Once you sign-in you’ll see the Windows Azure resources that you have permissions to manage show up automatically within the Visual Studio server explorer and be available to start using: No downloading of management certificates required.  All of the authentication was handled using your Windows Azure Active Directory! Manage Subscriptions across Multiple Directories If you have already have multiple directories and multiple subscriptions within your Windows Azure account, we have done our best to create a good default mapping of your subscriptions->directories as part of today’s update.  If you don’t like the default subscription-to-directory mapping we have done you can click the Settings tab in the left-hand navigation of the Windows Azure Management Portal and browse to the Subscriptions tab within it: If you want to map a subscription under a different directory in your account, simply select the subscription from the list, and then click the “Edit Directory” button to choose which directory to map it to.  Mapping a subscription to a different directory takes only seconds and will not cause any of the resources within the subscription to recycle or stop working.  We’ve made the directory->subscription mapping process self-service so that you always have complete control and can map things however you want. Filtering By Directory and Subscription Within the Windows Azure Management Portal you can filter resources in the portal by subscription (allowing you to show/hide different subscriptions).  If you have subscriptions mapped to multiple directory tenants, we also now have a filter drop-down that allows you to filter the subscription list by directory tenant.  This filter is only available if you have multiple subscriptions mapped to multiple directories within your Windows Azure Account:   Windows Azure SDK 2.2 Today we are also releasing a major update of our Windows Azure SDK.  The Windows Azure SDK 2.2 release adds some great new features including: Visual Studio 2013 Support Integrated Windows Azure Sign-In support within Visual Studio Remote Debugging Cloud Services with Visual Studio Firewall Management support within Visual Studio for SQL Databases Visual Studio 2013 RTM VM Images for MSDN Subscribers Windows Azure Management Libraries for .NET Updated Windows Azure PowerShell Cmdlets and ScriptCenter I’ll post a follow-up blog shortly with more details about all of the above. Additional Updates In addition to the above enhancements, today’s release also includes a number of additional improvements: AutoScale: Richer time and date based scheduling support (set different rules on different dates) AutoScale: Ability to Scale to Zero Virtual Machines (very useful for Dev/Test scenarios) AutoScale: Support for time-based scheduling of Mobile Service AutoScale rules Operation Logs: Auditing support for Service Bus management operations Today we also shipped a major update to the Windows Azure SDK – Windows Azure SDK 2.2.  It has so much goodness in it that I have a whole second blog post coming shortly on it! :-) Summary Today’s Windows Azure release enables a bunch of great new scenarios, and enables a much richer enterprise authentication offering. 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

  • Multiple IP addresses on one NIC register twice in DNS server

    - by Brad B.
    Hi, We've got a build server (Windows Server 2008 SP2, 64-bit) which has one NIC and two IP addresses registered to that NIC (192.168.1.30 and 192.168.1.31). The build server is registering two identical Host (A) records for itself in our DNS server: buildserver.example.com = 192.168.1.30 buildserver.example.com = 192.168.1.31 I know in the "Advanced TCP/IP Settings" window for the build server's NIC, under the "DNS" tab, there is a check box labeled "Register this connection's addresses in DNS". I only want ONE of the IP addresses (ending in .30) to be registered in DNS not both of them. Can that be done? My best guess is to disable the "Register this connection's addresses in DNS" and manually add the Host (A) record to our DNS server. Thanks for any help!

  • Resolving DNS queries for two disconnected, private, networks

    - by Mikeage
    I'm trying to setup two PCs (one Windows, one Linux, but my understanding is that this problem is more DNS and less OS) as follows: Home network: 192.168.1.0/24 VPN (via OpenVPN server not within the home network): 192.168.2.0/24 . I would like a PC on both networks to be able to access three different types of site: Internet addresses Addresses on the home network Addresses on the vpn However, I'm not sure how/which DNS servers to use. If I prioritize my home DNS server, I can resolve (1) and (2), but not (3). If I prioritize my VPN DNS server, I can't resolve addresses of type (2). Of course, looking up addresses via nslookup and explicitly setting the correct server works, so I know my local DNS servers are OK. Is there any way I can set up my PCs to fallback on the second DNS server if there is no response? Alternatively, is there any way I can tell different queries to go to different servers [maybe by setting up different subdomains; foo.local.something vs. bar.vpn.something]? Thanks

  • Change the order of DNS lookup when connected in the VPN

    - by qwerty2010
    Using Windows 7 Pro here. I have my LAN network adapter with DNS server 8.8.8.8 (Google's DNS). I also have OpenVPN client to connect to my company's network. If I type "nslookup" while disconnected from the VPN, I get 8.8.8.8 (from my LAN network adapter). If I type "nslookup" while connected in the VPN, I get the DNS IP from my company's network. That makes me think that when connected to the VPN all DNS's resolution are routed first to my company's DNS. How can I change this order, and make the DNS resolution be routed to 8.8.8.8 first, when I'm connected to the VPN? Thank you

  • DNS Server Behind NAT

    - by Bryan
    I've got a Bind 9 DNS server sitting behind a NAT firewall, assume the Internet facing IP is 1.2.3.4 There are no restrictions on outgoing traffic, and port 53 (TCP/UDP) is forwarded from 1.2.3.4 to the internal DNS server (10.0.0.1). There are no IP Tables rules on either the VPS or the internal Bind 9 server. From a remote Linux VPS located elsewhere on the internet, nslookup works fine # nslookup foo.example.com 1.2.3.4 Server: 1.2.3.4 Address: 1.2.3.4#53 Name: foo.example.com Addresss: 9.9.9.9 However, when using the host command on the remote VPS, I receive the following output: # host foo.example.com 1.2.3.4 ;; reply from unexpected source: 1.2.3.4#13731, expected 1.2.3.4#53 ;; reply from unexpected source: 1.2.3.4#13731, expected 1.2.3.4#53 ;; connection timed out; no servers could be reached. From the VPS, I can establish a connection (using telnet) to 1.2.3.4:53 From the internal DNS server (10.0.0.1), the host command appears to be fine: # host foo.example.com 127.0.0.1 Using domain server: Name: 127.0.0.1 Address: 127.0.0.1#53 Aliases: foo.example.com has address 9.9.9.9 Any suggestions as to why the host command on my VPS is complaining about the reply coming back from another port, and what can I do to fix this? Further info: From a windows host external to the network >nslookup foo.example.com 1.2.3.4 DNS request timeout timeout was 2 seconds Server: UnKnown Address: 1.2.3.4 DNS request timed out. timeout was 2 seconds 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 This is a default install of bind from Ubuntu 12.04 LTS, with around 11 zones configured. $ named -v BIND 9.8.1-P1 TCP Dump (filtered) from internal DNS server 20:36:29.175701 IP pc.external.com.57226 > dns.example.com.domain: 1+ PTR? 4.3.2.1.in-addr.arpa.

  • Change the order of DNS lookup when connected in the VPN

    - by qwerty2010
    Hi, Using Windows 7 Pro here. I have my LAN network adapter with DNS server 8.8.8.8 (Google's DNS). I also have OpenVPN client to connect to my company's network. If I type "nslookup" while disconnected from the VPN, I get 8.8.8.8 (from my LAN network adapter). If I type "nslookup" while connected in the VPN, I get the DNS IP from my company's network. That makes me think that when connected to the VPN all DNS's resolution are routed first to my company's DNS. How can I change this order, and make the DNS resolution be routed to 8.8.8.8 first, when I'm connected to the VPN? Thank you

  • how to configure my internal dns to resolve external resources

    - by Ralph Shillington
    I have an internal DNS as part of my AD setup. I have an hosted DNS for public resources (which are typically at some data centre somewhere) Occasionally while on our internal network I need to get to a public resource --- for example www.ourcompany.com since there isn't a www record in our internal DNS I cant get the name resolved. How do I configure my DNS to forward names it doesn't recognise to the public DNS. Update: As per the comment yes I have a "split-horizon" dns (which seemed like a good idea at the time) This AD setup is less than 24 hours old, and can be redone if need be -- (although I would rather not)

  • Change the Default Number of Rows of Tiles on the Windows 8 UI (Metro) Screen

    - by Lori Kaufman
    By default, Windows 8 automatically sets the number of rows of tiles to fit your screen, depending on your monitor size and resolution. However, you can tell Windows 8 to display a certain number of rows of tiles at all times, despite the screen resolution. To do this, we will make a change to the registry. If you are not already on the Desktop, click the Desktop tile on the Start screen. NOTE: Before making changes to the registry, be sure you back it up. We also recommend creating a restore point you can use to restore your system if something goes wrong. HTG Explains: Why Do Hard Drives Show the Wrong Capacity in Windows?

  • How to Skip the Start Screen and Boot to the Desktop in Windows 8.1

    - by Mark Wilson
    For almost everyone who made the upgrade, Windows 8 proved to be something of a disappointment for one reason or another. Windows 8.1 (or Windows Blue) was released to address many of the issues users had complained about including reintroducing the ability to boot straight to the desktop. Being able to boot to the desktop rather than the Start screen is something that people have been clammering for ever since the first preview versions of Windows 8 were unveiled. There have been various third-party tools released as numerous workarounds used to get around the problem, but now it is an option that is built directly into the operating system. You’ll need to have downloaded and installed the update in order to proceed, but once you have done this, things are very simple. When you have Windows up and running after the upgrade, right click an empty section of the taskbar and select properties to bring up the newly named “Taskbar and Navigation properties” dialog.  Move to the Navigation tab and look in the “Start screen” section in the lower half of the dialog. Check the box labelled ‘Go to the desktop instead of Start when I sign in” and click OK.

  • DNS setup problems with Windows Azure VPS

    - by jbigelow
    What is the proper to setup the A record (or CNAME) for a Windows Azure VPS? I can't connect to my website after setting up IIS and believe I don't have the correct DNS setup. I created a small VPS instance with the default Windows Server 2012 configuration. I RDP'd in and added the Webserver role. In my DNSMadeEasy control panel I added an A record with my Public Virtual IP Address. In IIS I went to the default website and added bindings for the hostname of my website, so I should be able to type mywebsite.com and see the IIS 8 splash screen, but instead my browser cannot connect. I attempted to navigate to the site by typing in my Virtual IP address into the browser and still cannot connect. I RDP'd back into the machine and turned off Windows Firewall. No change, still cannot navigate to my website. From within IIS I double checked my binding. If I click "browse *:80" I can bring up my website in IE with the http:// localhost address. If I click "browse mywebsite on *.80" IE says "This page cannot be displayed.", from within the RDP session I can view the site if I navigate to http:// 127.0.0.1 but not if I navigate to my Virtual IP, nor can I view the page if I try navigating to http:// mywebservername.cloudapp.net I'm thinking I must be fundamentally not understanding how do DNS setup with Azure VPS but my initial Google searches aren't turning up any helpful information. (spaces added after the http:// so serverfault doesn't try and render them as valid urls.)

  • Advance DNS - Redirecting Emails to new webhost

    - by Martin
    I am not to sure if this question belongs here but I will surely find out soon enough. I have two web hosts (Not sure why it has been setup this way but it has). I do not want to use the original web host to handle the emails as the Data that we get from them is 500 mb which is already full with hosting the website. The second web host has an unlimited data plan and was created so we could use this host for the email accounts. Now the problem is I have reset the Advance DNS Zone records on both accounts and I am not sure what they were before. (Silly me should have taken a backup of how it was setup before hand I know) Emails were working before and going to the second hosts server now they are going to the first host but it has no email addresses setup for use so all emails are bouncing saying that the address does not exist. Host 1 IP: 192.185.96.110 Host 2 IP: 27.54.88.66 So far I have changed the Advanced DNS Zone record on Host 1 with the following: A Record: mail.australisinstitute.qld.edu.au - 27.54.88.66 I have not made any changes on Host 2 and both hosts have the default MX Records. If I need to provide any more information I can but I just hope someone can decipher what I have said haha. Cheers in advance!

  • DNS Problems with .pt configuration

    - by Tony S.
    Hello everyone! I have a hosting service with aplus.net, however I had a need to register a .pt domain, but aplus doesnt have this service, so I contacted a .pt registar, called hostingbug.net, to do this. So now I'm owner of a .pt domain, lets say, example.pt. I gave hostingbug the aplus nameservers needed for propagation. And here began the problems. When hostingbug tried to configure, the following error was displayed: <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> @64.29.151.221 click.pt. NS +norecurse (1 server found) global options: printcmd connection timed out no servers could be reached And they told me that aplus.net needed to create a new dns zone for .pt domains. So I contacted aplus.net, and they didnt understand this issue, and told me that everything was fine with their servers, and sent me back to hostingbug. So I'm felling like a ping pong ball right now... How can I configure this "new dns zone" for .pt domains? Anyone have clue of how to do this so I can tell them? Or should I cancel aplus services? Thanks in advance
