Exchange 2013 Split DNS, how to get WAN clients to use public Split DNS IP when inter-office link is DOWN?!

Hello,
I have an Exchange 2013 deployment and a LAN/WAN setup, we have many small remote WAN linked offices that can resolve to the Exchange Server's internal IP.
Outlook clients in remote WAN offices work fine as long as the link is UP since the Split Brain DNS for Exchange will resolve the internal clients to the internal IP of the Exchange server, Outlook connects up without issues.
However, in the event of loosing connection to our remote sites, they will no longer be able to resolve to the internal Exchange IP, but they still have a backup public internet that they can use. So should the inter-office connectivity fail we have it setup
so clients in remote offices can still browse the internet, etc.
However, their Outlook fails to connect because it has a cached DNS record for our Split Brain Exchange DNS setup and tries to resolve it to its internal IP, instead of refreshing the cache and grabbing the public IP of the Exchange server since now they
would be resolving it over the public internet.
Is there anything I can do with my existing configuration to allow the client to pick up the public IP of the Split DNS setup when our inter-office connection is down and the client is no longer able to use the internal IP they have cached for Exchange?
I guess I could lower the TTL on the DNS record to something like 1 minute so it does not cache the DNS record / IP for long? Is this the best approach?

http://public.wsu.edu/~brians/errors/lose.html
I would suggest that the best approach is to either improve the reliability of the WAN link or to configure DNS to always use the Internet path.  You might want to work with your network guy, perhaps there's a way to have your gateways automatically
switch to an Internet VPN backup when the WAN link is down or something like that.

  • How to get W530 laptop to use only the Quadro GPU when using 2 display panels?

    QuestionI just purchased a W530 and it has both video card -  Quadro 1100M and Intel Graphics 4000 graphics. 
    From the control panels for each of the graphics cards it seems that the laptop display is connected to the Intel Graphics card whereas the Quadro is connected to my external monitor.  Is there a way to configure this setup so that the laptop display uses the Quadro as well just like the external monitor does?
    AnswerUnfortunately the Optimus set up is that no matter which card is used, the Intel HD4000 card powers the display.
    However, if you want to always use the nVidia discrete card, you can turn optimus feature off in the BIOS by setting the Graphics setting to "Discrete". Please bear in mind that this will drain the battery very quick if no power AC adapter is attached.

    The Bios trick does the job, however then you will be stuck with a really low cpu speed on battery power unless you disable the cpu speedstep from bios. I had the w530 with quadro 2000m for two years and i had the optimus disabled since day one. The battery last little over two hours with optimus disabled, if you also disable speed step then you only have about an hour of battery power. I had to do this a few times when i had to render something quickly out of media encoder with battery power.

  • How to get web application to use Tuscany without conflicting with SAP SDO

    Hi,
    We are attempting to run a web application on SAP NetWeaver CE 7.1 SP1 which uses Tuscany SDO.  As it now stands We must use Tuscany because the web application will not run with the SAP SDO implementation provided by Netweaver. To ensure that Tuscany is loaded with priority, we have packaged the Tuscany JAR files and their dependencies as a heavy resource, as described here:
    http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/60642a88-95fe-2b10-d387-a245d48fc257?overridelayout=true
    The final check showed that Tuscany was correctly deployed as a heavy resource and included the following JAR files:
    common-2.2.3.jar
    ecore-2.2.3.jar
    ecore-change-2.2.3.jar
    ecore-xmi-2.2.3.jar
    tuscany-sdo-impl-1.1.1.jar
    tuscany-sdo-lib-1.1.1.jar
    tuscany-sdo-tools-1.1.1.jar
    xsd-2.2.3.jar
    We also verified that the web application using Tuscany has a hard reference to the Tuscany heavy resource.
    However, when we try to run the web application, the following error is logged:  java.lang.LinkageError: Class commonj/sdo/DataGraph violates loader constraints
    The issue is definitely due to some kind of classloading conflict with the SAP SDO library, as the application runs normally when SAP SDO is manually removed from the classpath. Doing this on a production system is unfortunately not an option, though.
    So the question is: how to get web application to use Tuscany without conflicting with SAP SDO?

    I took a look at the "printerReady" example.  Looks like I may be able to use the InetPing (...) function to ping through a range of IP addresses looking for a response.
    Any ideas on how to find the MAC address associated with the IP addresses that respond?
    We may have multiple units responding and the MAC address will allow the operator to determing which unit to connect to.
    I'll try the InetPing to see how it works,

  • Since I upgraded to os 5.1 for my iPhone I can no longer type in reminders. Any suggestions how to get around having to use siri for reminders?

    since I upgraded to os 5.1 for my iPhone I can no longer type in reminders. Any suggestions how to get around having to use siri for reminders?

    Unfortunately, I have a very similar problem. Since I upgraded to os 5.1 on my new iPhone 4S the reminders screen will not add new reminders or scroll up and down. What's more strange is the screen will still scroll side to side allowing access to the Completed list, and both the Completed list and Date functions work normally so this must be an upgrades glitch.

    Hi,
    The events of BDT can be used to default some fields on creating a partner.
    For this create a function module for ISDAT. attach that event in BUS7.
    In the ISDAT funtion modulethe following code should be used.
    For example to set the nationality:
    I_BUSDEFAULT-NATIO = 'DE.
    CALL FUNCTION 'BUP_BUPA_FIELDVALUES_SET'
    EXPORTING
    i_busdefault = I_BUSDEFAULT

  • In iphoto how to get the gold you delete a photo warning message when you check the box not ask

    in iphoto how to get the gold you delete a photo warning message when you check the box not ask

    Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder.
    (On 10.7 or later: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)
    (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
    What's the plist file?
    For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.

    I have a JVC video camera and it records the video to a .mod format (which Apple devices don't support). I figured out how to get them to iPhoto using iMovie but I want to be able to get the videos on my iPad 2 but it won't let it sync. Any help?

    Thanks for that. Much more constructive than the last comment. It's only the restriction code I can't recall, not the access passcode. So I can currently access the device, just not age restricted content. Does that's make a difference? I also wondered if anyone knew how many attempts you get to try to get it right. Now tried 21 times and so far nothing bad has happened but I am concerned I'll eventually be completely locked out of the device. That doesn't seem in the spirit of things though. Surely it's foreseeable that a child could repeatedly try to guess the code so I can't see that it would be right to lock the device down completely in that circumstance, particularly if the access code is being typed in correctly every time.
    Thanks

    1) Whenever you pivot rows to columns, no matter what version of Oracle and no matter what method you use, you have to decide in advance how many columns you are going to have and what the names of the columns are. This is a requirement of the SQL standard.
    2) I use the WHERE clause to get just the data for this year
    3) With EXTRACT, I get just the month without the year.
    4) Using DECODE, I put every month's data into the correct column
    5) Once I do all that, I can just GROUP BY order_code while SUMming all the data for each month.
