Are Registrar pool and Front end pool one and the same?

Hi,
What is the RegistrarPool parameter which is used in Enable-CsUser command? 
Is it same as Front end pool because whenever I search for information on Registrar pool, I end up with the links explaining about Front end pools? 
Are there any msdn or technet links which talk about this?
Thanks in advance,
Sandeep

Hi Sandeep,
The registrar pool is the pool where user's Lync account is homed.
So if you have a single pool in your Lync environment, then the registrar pool will be same as front end pool. If you have multiple front end pools and you want to find out a user's registrar pool, you can
1. either check the user account in control panel 
2. Check the parameter RegistrarPool for a user by running "get-csuser -identity useralias" 
Hope this helps.
Regards,

    My Apple ID (email address) is somehow registered to the US store even though I live in the UK. Is there any way I can close the US account and open a UK one with the same ID/email?

    No, but you can change the country of your iTunes Store account. Sign into your iTunes Store account and click the "change country" link. You'll need a valid UK credit card to complete the change. If you have any credit balance remaining, you'll need to contact the iTunes Store to clear that for you before you'll be able to change the country.
    Note that if you purchased anything from the US iTunes Store, you probably will not be able to re-download it nor update apps once you change the country. So you may prefer to set up a new email address so you can create a new account in the UK iTunes Store. You can change the email address to which receipts and other notices are sent to your actual email address, if you prefer.

  • Admin and Task servers as one in the same

    I open up the Remote Desktop software, and select 1 computer from the list. I then click on the "Install" icon and drag a .pkg file inside of the "Packages" area. I check off the radio button that says "Run this task from: The Task Server on this computer" and click the "Install" button.
    I get a progress bar that runs infinitley and a message that says "The targetd computer, "<computer name>", is currently idle. It doesn't matter if the computer is up and running, or if it is offline. It says the same thing regardless and never installs the package.
    If I decide not to "Run this task from: The Task Server on this computer" and instead "Run this task from: This application" then it works prefectly. I just can't seem to install from the local task server, which means I have to wait until this machine is online before I can manually run it, which means there's a problem with the way I set up the Task server.
    Does anyone have any idea what's wrong with my installation? I have gone into "Remote Desktop -> Preferences -> Task Server" and made sure "Use Task Server on this computer" was selected, and it is. I am NOT using 2 different serial number for 2 different and separate copies of ARD3 for both an Admin + Task Server. I am, however, expecting the Task Server and Admin Server to run as one in the same. If this is not possible then perhaps the Documentation needs updating? From http://images.apple.com/server/docs/ARDTaskServer.pdf I read: "You can run the Task Server on either the administrator computer or a dedicated remote computer. The default Task Server is the administrator computer on which you installed Remote Desktop.". This means the Admin and Task Servers can run as one in the same, no? Please let me know if this is incorrect.

    Update: Please refer to the post with the title of "Possible to run both an Admin Server and Task server from the same host?". Basically the answer to this problem is that there isn't one. I've called apple support and it's been confirmed that an Admin server and Task server CANNOT be run from the same installation on the same host. I suppose you could say the answer is to buy another license of ARD3 and run it in a separate host, but for some of us this isn't an option - especially for a very small startup.

  • New Macbook Air i5 wireless is very slow and disconnect again and again. Any one has the same issue or some help??

    I recently bought a new 13 inch Macbook air and wireless internet is really slow and disconnect again and again. However I hav another windows laptop at the same place and that never disconects or looses signals? wireless on this mac is too slow that I cannot even use to make a skype call. I am new mac user and getting a bit disappointed because of this bad performance.I googled about this issue and found that lot of people are having the same issue with macbook air. I switched off the bluetooth adaptor but still no progress. Any help will be appreciated. Thanks

    I am experiencing something similar with my MBA 13"/i5/256GB.
    To take it one step further, I started up a Terminal session and ran a ping against my wireless router. I see the same pattern repeated over and over: I get about 5 or 6 pings through, then 4 or 5 misses, then it reconnects again. When it reconnects, the first ping or two have times in thousands of milliseconds, where normal is maybe sub-millisecond to 4ms for the remaining few seconds.
    I have other wireless devices, including iPhone, iPad, and an older MacBook - all work fine. The MBA is the only Lion device.

    You have to remember either the BlackBerryID password, or the secret question answer. Without either, you're stuck.
    Your choices are:
    --Use another email account to create an entirely new BlackBerryID (with which you will lose access to any purchased apps using the "forgotten" first BlackBerryID, or
    --Find the initial email you were sent to confirm the initial BlackBerryID, and in it is a link to click to cancel and delete the account. Click on that, delete the account and then you can use that same email to create an entirely new account.

  • Lync 2013 On Prem - Front End Pool - Second server in pool becomes unavailable when first server is offline

    We have one front end pool, that contains 2 front end servers running Lync Server 2013.
    When the first server, LFE01 goes offline (to be restarted for instance), the second front end server LFE02 in the same pool's Lync services will suddenly stop and will refuse to start until LFE01's Lync services have started again.
    During this time, the Lync client will go from full functioning mode whilst LFE01 is up and running, to reduced functionality (when LFE01 is restarting), to the user being signed out of Lync and not able to log back in. As soon as LFE01 comes back up, users
    can log back in to Lync.
    We'd ideally like LFE02 to take over the front end server role whilst LFE01 is restarting, and vice-versa.
    Checking the event logs on LFE02, I can see the following errors when LFE01 is offline:
    This process was not able to update its health status
    The Audio-Video Conferencing Server failed to send health notifications to the MCU factory at https://frontendpool.contoso.com:444/liveserver/mcufactory/. 
    Failure occurrences: 30, since 7/11/2013 3:40:38 PM.
    Cause: Either the Front End service is not running, or poor network connectivity.
    Resolution:
    Verify that the Front End Service is available, and its machine is visible over the network.

    Failure occurrences: 30, since 7/11/2013 3:40:42 PM.
    Cause: Either the Front End service is not running, or poor network connectivity.
    Resolution:
    Verify that the Front End Service is available, and its machine is visible over the network.
    Server startup is being delayed because fabric pool manager is initializing.
    Cause: This is normal when Pool is bootstrapped and indicates that the Front-End is waiting for a quorum of other Front-Ends to be started.
    Resolution:
    If this event recurs persistently, ensure that 85% of the Front-Ends configured for this Pool are up and running. For 2 or 3 machine Pools, initial cold-start of the Pool requires all machines to be started. If multiple Front-Ends have been recently
    decommissioned, run Reset-CsPoolRegistrarState -ResetType QuorumLossRecovery to enable the Pool to recover from Quorum Loss and make progress.
    Does the first server in the pool need to be up at all times for the second server to be running? If so, I may need to re-plan my redundancy.

    I can't believe how inaccurate these statements are. 
    Yes as per Microsoft it is best practice to have 3 FE in a pool but that absolutely does not mean that if you have 2 FE server in a pool that your pool will stop working!!
    In case when you do have 2 FE servers in a pool your Back End primary database server will act as a vote to keep the quorum for single server still left in a pool and all your clients will keep operating in a pool with one FE still running. 
    The problem with having 2 FE in a pool as per Microsoft documentation is as follows:
    If one of the two Front End Servers goes down, you should try to bring the failed server back up as soon as you can. Similarly, if you need to upgrade one of the two servers, bring it back
    online as soon as the upgrade is finished.
    If for some reason you need to bring both servers down at the same time, do the following when the downtime for the pool is finished:
    The best practice is to restart both Front End Servers at the same time.
    If the two servers cannot be restarted at the same time, you should bring them back up in the reverse order of the order they went down.
    If you cannot bring them back up in that order, then use the following cmdlet before bringing the pool back up:.
    http://technet.microsoft.com/en-us/library/gg412996.aspx
    I tested this in my environment which I currently am running with 2 FE servers and I can categorically confirm that pool will continue operating. 
    However, with all this said I did notice that clients with connection to FE server that is shut down take anywhere from 2-9 min to reconnect. I was trying to figure out why such a long delay until clients reconnect. Possibly it might be because there are
    2 FE servers in a pool and Back End server is taking a while to vote in turn delaying auto reconnect process for clients. Second possibility that I'm looking into is that we deployed HLB for sip traffic internally as well and I'm curious if using DNS LB would
    fix this delay.
    I'm just so disappointed how inaccurate some of these accepted answers above are.

  • If i cancel an account can I create a new one with the same e-mail address?

    I made an account with Game Center and I wanted to use it to get some free apps on the iTunes Store. When I tried to sign in on iTunes (for Windows) it said I had to review my details. I didn't have a credit card so I couldn't complete it and there wasn't any option for no credit card.
    I wondered if I could cancel my account and create a new one with the same e-mail address. There was a discussion that you could create a new account on the iTunes Store and have the choice to not have a credit card.
    Any help will help!
    SuperHoops

    No, it does not, not if the creation of the Apple ID was completed, which unless you are referring to a different Apple ID I presume it did since you are posting here. And once created, you can't get apps without providing a payment method; setting up for just free apps requires a very specific procedure or a payment method is necessary. Creating an account via Game Center does not work.
    If you can create a new email address (Gmail or Yahoo mail will work), take a look here:
    http://support.apple.com/kb/HT2534
    Read the steps carefully as the order in which you follow them is critical. Note that you can do this only when creating a new Apple ID. You cannot use an existing ID. 
    You will of course not be able to get anything other than the free apps without entering in some sort of payment method (credit card, prepaid iTunes card, gift certificate, etc.)

  • Lync Server 2013 Front End Pool Mediation Service only works on one node

    Hello, I'm currently experiencing an interesting issue with a Lync 2013 Front End Pool implementation on a customer, and I don't know if this is by design or am I missing something.
    We implemented 3 Enterprise Front End Servers in a Pool with a hardware load balancer and we have them configured also as a mediation Pool.
    We have a SIP trunk to an Avaya PBX which was perfectly working before on a Lync 2010 Implementation that we migrated to these new 2013 Front End Pools.
    Now the SIP traffic is only working when configured directly to one node of the pool. If we configure it to any other node the calls fail. We also tried configuring the HLB for port 5060 for the pool and pointed the PBX to that IP but the calls also fail.
    Searching around I read something about that the PBX has to be Lync certified in order to use DNS load balancing to send SIP traffic to the mediation pool, however, I don't think DNS load balancing will work because the other nodes doesn't connect the calls
    from the PBX, only one node appears to be listening for the SIP Trunk.
    I also restarted the mediation service on one  non-working mediation server node and the event viewer on the working mediation server node showed events that it restarted the service, Not the non-working one, it's like only one server from the pool
    is doing as mediation server. 
    So even if I get a Lync Certified PBX/Media Gateway, the mediation service doesn't appear to be load balanced, or how does it work in order to do that?
    Thanks.
    Eduardo Rojas

    Just a few things about what should be happening.  Each front-end server should be listening on the port configured in topology builder for the mediation service. So if that is port 5060, verify that you see that port listening on all front-end servers
    by running a netstat -ano.  From a local workstation, also make sure you can connect to that port via a telnet IPAddress 5060.  As you say, you should be able to send any of the three mediation servers an inbound call.
    Outbound calls will round robin out of the enterprise pool.  So you shouldn't see all of the calls coming out of a single server.
    A few other items I would look into:
    - Make sure your ports are right.  Ensure that you are matching ports on the Avaya and Lync.  It's not a hard requirement but makes life easier to troubleshoot.  So if the Avaya is 5060, just make sure TCP/5060 enabled in your mediation pools
    and that your gateways/trunks are also set to TCP/5060.
    - Look outside the Lync Event Viewer and see if anything strange (.net errors) are being tossed anywhere else during startup of the mediation service.  I once had to remove the mediation server installer (Program and Features | Remove) and rebootstrap
    the server because something went sideways during an install.
    Thanks,

  • Could you tell me if it would be supported to pair a two node enterprise edition front end pool inc mirror sql with a one node enterprise edition front end pool inc single sql?

    Hi all,
    Could anyone tell me if it would be supported to pair a two node enterprise edition front end pool inc mirror sql with a one node enterprise edition front end pool inc single sql?
    MUCH THANKS.

    The answer from TechNet found at http://technet.microsoft.com/en-us/library/jj204697.aspx Is, and I quote:-
    Enterprise Edition pools can be paired only with other Enterprise Edition pools. Similarly, Standard Edition pools can be paired only with other Standard Edition pools.
    Also, "Neither Topology Builder nor topology validation will prohibit pairing two pools in a way that does not follow
    these recommendations. For example, Topology Builder allows you to pair an Enterprise Edition pool with a Standard Edition pool.
    However, these types of pairings are not supported."

  • Front End pool failed over

    Hi all,
    1. I setup a pool with three Front End servers (FQDN of pool is pool.site1.sip96x2.com and it's pointed to IP address of three Front End servers). Everything works fine. But When I disable network interface on FE1 and FE2, the Lync clients are disconnected.
    I haven't understood clearly how the Lync clients failed over in a pool? Please clarify to me.
    2. I have two central site (Root site and Primary site, they have different domain sip96x2.com and site1.sip96x2.com). The simple URL dialin is pointed to Front End server at Root site. So if the link between Root site and Primary site is down, how can the
    users at Primary site connect to dialin URL? 
    3. In building topology for Front End pool, I checked Override FQDN internal web service and the FQDN is "poolint.site1.sip96x2.com". I created three A records "poolint.site1.sip96x2.com" and pointed to three IP addresses of Front End
    servers. Is it right?
    Thanks so much!

    Ah ok, well first thing if I am reading this correctly, pool pairing Standard with Enterprise is not supported. You should only pair Standard with Standard and Enterprise with Enterprise (even though topology builder won't stop you) Take a look here for
    support scenarios http://technet.microsoft.com/en-us/library/jj204697.aspx
    To deal with the simple URLs in the event of failover you need to add them using Powershell. Take a look at this article which explains and gives an example: http://blogs.perficient.com/microsoft/2012/01/configuring-simple-urls-for-multiple-lync-pools/

  • Lync 2013 Edge server compatibility with Lyn 2010 Front end Pool

    Hi All,
    Technet article (http://technet.microsoft.com/en-us/library/jj688121.aspx) says the following:
    If your legacy Lync Server 2010 Edge Server is configured to use the same FQDN for the Access Edge service, Web Conferencing Edge service, and the A/V Edge service, the procedures in this section are not supported. If the
    legacy Edge services are configured to use the same FQDN, you must first migrate all your users from Lync Server 2010 to Lync Server 2013, then decommission the Lync Server 2010 Edge Server before enabling federation on the Lync Server 2013 Edge Server.
    Can you tell me why it is you have to change the External Lync Web services URL during a migration to Lync 2013 from Lync 2010. What purpose does this serve?
    Also can you clarify this and explain why this is required, why would you have to migrate all of your users, would a Lync 2013 Edge not talk to a Lync 2010 front-end?
    Any help would be much appreciated. MANY THANKS.

    Thank you very much for all your inputs.
    We still have few questions:
    Questions:
    Can you tell me if Lync 2010 users will be able to login using mobility if we repoint the reverse proxy (TMG) web services publishing rule to the Lync 2013 server? Remember both systems Lync 2010 and 2013 are using the same web
    services URL so they will both end up at the Lync 2013 server. Alternatively if not we will migrate all users to 2013, this is not a problem
    In addition to this I cannot find anything that states how Exchange UM will operate when you are running from a backup pool and the exchange UM contacts are not available because they are homed on the server that is down. This
    configuration is 2 x standard edition servers pool paired. How can we make sure Exchange voice mail works during a pool failover?
    Call Park is not clear to me I read the following:
    Lync Server 2013 provides new disaster recovery mechanisms in the form of failover and failback processes. These failover and failback processes support recovery of Call Park functionality by allowing
    users who are homed in the primary pool to leverage the Call Park application of the backup pool when an outage occurs in the primary pool. Support for disaster recovery of the Call Park application is enabled as part of the configuration and deployment of
    paired Front End pools.
     Is this saying we need to deploy Call Park in the DR pool and use a different range of orbit numbers, or can we use the same range in the DR pool?
    Further, I can see that Common Area Phones will be fine as they will log into the DR pool automatically. Response Groups need to be exported and imported to the DR pool. Incidentally these did not migrate well at all and have
    caused us a big headache!
    Any inputs will be greatly appreciated. Thanks again for all of your time.
