Does NLB also works as fail over?

I have 2 WFEs and Windows NLB. I want to know if NLB also works as fail over i.e. if one of the WFE goes down, will it detect and then never send request to that WFE until it comes back online?
I am asking because I stopped IIS on one of the WFE and now the SharePoint site won't open. Looks like NLB is sending request to that WFE which is down.

I am using Windows NLB and I have come to know that it doesn't check whether IIS on particular server is running or not. It simply checks if the server itself is up and if it is then it sends request even though IIS is down.

  • Does AirPrint work with all kinds of printers with modern usb capability? Does it also work with android based devices?

    Just as the question says

    Does AirPrint work with all kinds of printers with moden usb capability.
    AirPrint works if you have an AirPrint compatible printer.  See this Apple support document for details on compatible models.
    http://support.apple.com/kb/HT4356
    If the printer is not AirPrint compatible, it still might be possible to enable printing by installing an App like Print Central on the iPad, iPhone, or iPod.

    Does it also work with android based devices?
    I would be surprised if it did, but best to ask that question on an Android support forum.

  • Extension Mobility not working during fail over

    Hello All
    I am John.   I have a cluster that has 2 subscribers and 1 publisher.  We are running 8.5.1.  Yesterday I had a case where my one subscriber had failed and everything failed over to the other subscriber.  Everything but extension mobility seemed to work.  I checked all my certs, I checked the services, I checked the url for the services.  Everything seemed to check out correctly.  The url is pointed to the publisher and the publisher was available. 
    What i saw during failover:
    When the services button was activated I received the requesting notice.  after a while the message changed to Host not found.  Then the next message was select service. 
    I did a restart on the extension mobility service with no effect.  The other web applications (such as corp directory) all seem to be working correctly.  Extension Mobility is the only service I have running.
    When the failover ended and my lost subscriber was available, extension mobility and the services started working again. 
    Any help or ideas would be greatly appreciated.
    Thank you
    John

    Hi John,
    As suggested by iptuser55, switch on the EM service on both the nodes. This is the only way failover would work. There are 2 services in CUCM, Extension Mobility and EMApp. The EMApp runs on all the nodes, and its job is to keep a list of the nodes with the EM service activated. When the top node in that list goes down, the EMApp will then point to the next node in the list, which will act as the Failover.
    Here's the architecture of the EM service.

  • How robust is PDF-Password protection? Does it also work for PDF/A?

    Several sources say that PDF passwords can be removed with appropriate software. Is this true?
    Can I also protect a PDF/A with a password? If not, how can I be sure that I can still open a regular password protected PDF in 10 years from now?
    Many thanks.

    Actually PDF/A is specifically designed to guarantee that the documents can be read in the distant future (barring global destruction, end of reality as we know it, alien sheep invasions, etc.)
    While we cannot predict which vendor will be providing the software to do it, or how the data will be stored by then (holographic data mice are still in beta) the PDF/A standard is designed to do two very important things:
    The standard is open, so the structure of a PDF/A file can be interpreted by anyone who can open it and compare the contents to the standard (which itself is also published in PDF/A). It's basically a text file with lots of symbols in it.
    PDF/A forbids any encryption or licensed algorithms (e.g. H.264) that could be impossible or illegal for a future viewer to use, for example if a password is lost or the inventor of a proprietary algorithm goes crazy and cancels all the licenses.
    Combined, these points make PDF/A impossible not to be parsable. It may end up projected directly into your brain by the aforementioned holographic data mouse, but you'll be reading it all the same.

    As to your ability to open a secured password in 20 years from now? Heck there is no guarantee that your non-secured pdf file will be readable in 20 years. With PDF/A your chances are pretty good as it uses standards based file format, but there is no guarentee that Adobe or any other company doing business today will be in business 20 years from now.

  • For the Creative Suite 6 Master Collection Student and Teacher Edition it says the platform is Windows. Does it also work for Mac?

    I have a Mac Book Pro, and i need this collection but it say's on the order sheet(after you press buy) that it is a Windows platform. Can this be made to work for a Mac platform as well?

    Go back and start over... before you commit to the purchase there should be an option to change from Windows to Mac... I know there is for regular CS6, and the Education version should have that same option
    I just changed the platform from Windows to Mac by clicking the little down arrow and selecting

  • How does BPM continue when a fail over ocurrs?

    Hello,
    If a BPM is running inside a cluster of XI, and the node  running the BPM fails, Would the other nodes continue processing or the BPM will finish with a error?
    Best regards,
    Luis Carlos

    Hi Luis,
    There is no automatic failover mechanism is there , if BPM fails. Rather if you consider your Scenario, then BPM will be a part of your end -to-end scenario. So it should execute sequentially.
    It is just my view...

    They work pretty good, & are across the device. Read here:

  • After adding 2nd WiSM and failing over AP's some apps don't work

    We have a dual core made up of 2 6513's. In 6513#1 we have WiSM#1 which we have had for sometime now. We have added a 2nd WiSM in 6513#2 for redundancy purposes also we are going to be re-configuring the WiSM in 6513#1 to more match that of the new WiSM in 6513#2. We have installed the new WiSM and failed over the AP's from 6513#1 so we can re-configure it's WiSM. The failover went great and no issues, with the exception that a web application or two didn't function from wireless clients and users were having issues getting to some mapped drives. The only difference from the new WiSM config vs the old WiSM is that on the old WiSM the AP's were in the same VLAN as the controller management interfaces. Now with the new WiSM it's configuration has the controllers AP mgt interfaces ip addresses in a different VLAN from the AP's, we are doing this based on Cisco best practices. If we revert the AP's back to the original WiSM/controllers the PC's where they are on the same vlan/subnet the applications and shares that were having issues the other way work. We have placed a call with Cisco TAC and they say our configs look good and we even sent them some packet captures and they said everything looks normal. The wireless clients can ping and resolve the server hosting the application database just fine.
    Thanks

    We did create the mobility groups, and we are using DHCP opt 43. The AP's find the 2nd WiSM#2 just fine and associate to the controllers and all the WLAN's work just fine. The only issue is that after the AP's are on the new WiSM and controllers there is an application or 2 that is having trouble locating it's database server and that some share's are not working. Again the only difference in this new setup in that now the AP's are on a different subnet/vlan from the controller mgt addresses where as before they were in the same subnet/vlan and the application and shares worked fine. It's almost like it is a bit of a routing issue?
    Thanks

  • Firefox Proxy Fail-over is not working correctly

    I am in a corporate environment, where we must use a complex auto-proxy, by configuring an automatic proxy configuration of http://proxyconf/proxy.pac. I am seeing an intermittent failure with Firefox 3.6.13, where the same site will load after a delay in IE (e.g. it works for half an hour, then fails for a while, etc.).
    By using Wireshark and tracing the packets, I have identified that a proxy server is intermittently failing, and Firefox is failing to try the second proxy. The auto proxy rule that is being invoked is:
    if (!isResolvable(host)) return "PROXY 172.16.39.201:8080; PROXY 10.241.32.28:8080";
    The problem is that Firefox is never failing over - it tries the 172 address 6 times in a row, then gives up and displays the "The proxy server is refusing connections" "Firefox is configured to use a proxy server that is refusing connections." "* Check the proxy settings to make sure that they are correct." "* Contact your network administrator to make sure the proxy server is working." error message. It continues with this behavior regardless of how many attempts, reloads, restarts are tried.
    IE on the other hand will try and fail with the 172 address, and then start using the 10. address (which works correctly). Several other applications also work correctly, such as IRC clients.
    Obviously the corporate proxy that is failing must be fixed, however Firefox is failing to utilitize the 2nd proxy after the first one fails.
    Seems like a bug.
    Is there some easy way for me to replace the proxy file with my own file? E.g. replace http://http://proxyconf/proxy.pac with file://c:\..., or use some add-on?
    It must be an autoproxy script, as there is no single proxy that I can use for all addresses.

    You can correct this issue by forcing the file blocklist.xml to update or wait until Firefox updates the file.<br />
    That update will remove the severity="0" flags in the file that cause the problem.
