Lync 2013 - Number of FE servers in paired pools

Hi,
We have an Ent. Edition Lync 2013 pool with 4 FE servers, we would like to implement a second pool at a different location for disater recovery.
Does the DR pool which will be paired with production one need to have exactly the same number of FE servers or can it have less (i.e. 3) ?
Thanks for your help,
Luca

You can have 1, or 3, or whatever number, it just has to be Enterprise to match Enterprise, you can't use Standard Edition with Enterprise for example.
Per: http://technet.microsoft.com/en-us/library/jj204697.aspx
"Each pool in a pair should have the capacity to serve all users from both pools in the event of a disaster."
That's not a statement on the number of servers, just the capacity to do what you need to do if you fail. It's sort of an obvious statement that speaks to load sharing among pools. Don't max out two pools and expect to be able to fail over to
one and run at full capacity.
In a DR situation, you may not need full capacity, so the amount of resources you'll be giving it will be based upon your own internal best practices.
Edit: And finally, yes I've done exactly what you're asking, it's fine.

Maximum number of Edge servers within a Pool for Lync 2013

I see no reference as to the maximum number of Lync Edge servers within a pool. Does it follow the same as that of the Front End, and so, no more than 12 per pool?
Also, can you have more than one edge pool within the same data center? I don't see why not, though validation is needed.
Thanks,
Christian
Christian Frank

Maximum no. Edge Servers 12,000 concurrent remote session

Merge Lync 2013 Edge servers in same pool

Hi guys.
- We had Lync 2013 FE STD version.
- We have added one more Lync 2013 FE STD and done front end pool pairing.
- We had single Edge Pool, soo only 1 EDGE server being in 1 POOL.
We wish to add another Edge server and put previous and this new Edge server in one pool.
This is a printscreen of our current Edge Deployment.
Because we have a federation enabled with external partners who had put in their lync configuration
to trust to our public external address of current edge server: LyncEDGESIP.domain.com, we would like to avoid sending them new address and we have decided to keep that public address and make it EDGE POOL NAME where both edge servers would be inside.
Now we are little bit confused/amused what to do next.
If use LyncEDGESIP.domain.com to be FQDN of EDGE POOL with 2 two edge servers, what would we need to do with our current edge server.
What to put for:
Access Edge Service public address on both edge servers
Web Conferencing Edge Service public address on both edge servers
A/V Edge Service public address on both edge servers.
bostjanc

Go with cutover migration if you can take downtime. Here is the high level summary for your reference;
Remove existing edge server from topology and publish the changes.
Create a new edge server pool in topology builder.
Make sure that access edge , web conference edge and AV edge name remains the same.
Publish the topology and run the setup on both edge servers. You need to configure external and internal IP addresses based on Lync topology.
Replicate the configuration change and run the deployment wizard.
Import the certificate and start the services.
Create additional DNS A records for load balancing externally.

Lync 2013 High Availablity in Pool

Hi MS recommends to have 3 FE servers in Lync 2013 Pool. I have few questions to clarify
1. why MS says if we have 2 FE servers then it will work as Lync 2010. what makes the differences between Lync 2010 (with 2 FE servers and Lync 2013 with 3 FE servers)
1. with 2 FE servers in Lync 2013 pool, what will happen if my BE server goes down?
3. I know the quorum used in Lync 2013 High availability (windows fabric) . Where the quorum will be stored? what model it is using?
Thanks

Enterprise Edition pools now are recommended to have a minimum of three, yes THREE front-end servers. This is due to the "Windows Fabric" replication architecture based on Azure. The back-end SQL database is no longer the store for real-time data.
If you BE Server down, Lync will work for 10 min. then become down
In order to function the Windows Fabric needs to achieve a status of Quorum. This means a certain number of servers (Voters) must be able to communicate with each other to ensure that the pool is capable of maintaining consistency (Quorum). There are 2
different pool states in which we must maintain\achieve quorum which differ in how many voters must be available.
Cold Pool Startup\Quorum Lost – when a pool is first starting or after quorum has been lost, that pool must have roughly 85% of its servers available to achieve quorum1.
Operating Pool – after a pool has been started we need at least 50% of the servers available to maintain quorum2.
1 This means that when defining a pool within topology builder only add the servers that will be deployed at that time, not in the future. If you put 6 servers in a pool within topology builder and only deploy 3, we will never achieve quorum because
we don’t have approximitley 85% of the servers operational. Thus, the front end services will never start.
2 If quorum is lost then all Front End services will be shutdown to protect the cluster from data loss.
To identify the Quorum voters a given servers Windows Fabric identifies check C:\ProgramData\Windows Fabric\Settings.xml. This file is updated when the Windows Fabric Host service starts up, thus any changes to pool members requires a service restart on
all Front Ends in the pool, one at a time. The To-Do list in topology builder lets you know that after publishing the topology. If this isn't completed your servers will have a skewed view of the topology which could cause issues. Depending on the number
of servers within the pool, this will dictate which voters are required.
Even # Server Pool (Figure 1) – each server will have 1 vote and the SQL instance will have 1 vote. The SQL server will act as a tiebreaker.
Odd #Server Pool (Figure 2) – each server will have 1 vote.

Lync 2013 DNS records

Hello,
Have been working on my Lync 2013 deployment for a while and until today I am still not quite sure about some DNS entries, especially confused by MS planning tool DNS Report. Here is my setup:
2013 enterprise, 3 FE servers in a pool (lyncpool01.domain.local), 3 BE SQL servers, 1 WAC server in a farm (wacfarm.domain.local) , Kemp HLB (cswebint.domain.local and wacfarm.domain.local), TMG server as reverse proxy and 1 edge server ( lyncedge01.domain.local)
in a pool ( lyncedgepool.domain.local)
sip domain name: domain.com
Please help to clarify, in "domain.com" zone on my internal DNS server
1) lyncdiscoverinternal.domain.com:
MS planning tool does not have it in DNS report. Should I point it to lyncpool.domain.local as a CNAME record, or 3 A records pointing to the FE servers, or point to the reverse proxy server external DMZ address?
2) _sipinternaltls._tcp.domain.com
MS planning tool says pointing to lyncpool01.domain.local, should I point it to sip.domain.com?
3) cswebint.domain.local and cswebext.domain.com
Should I point both to the VIP of the kemp HLB?
4) lyncdiscover.domain.com
Should I create 3 A records pointing to the FE servers, or one CNAME record pointing to lyncpool01.domain.local?
Thanks in advance.

Let me see if I can help you make sense of what you have:
1. LyncDiscoverInternal
You don't really need this record as lyncdiscoverinternal just will re-direct you back to lyncdiscover.
2. _sipinternalts
This should be in your internal DNS SRV records point to lyncpool.
3. Are you using your Kemps for HLB for all Lync services and/or Lync Web Services?
I'm going to guess below without knowing:
cswebext = your external DNS A record for Lync Web Services connectivity point to your reverse proxy solution. If that is the Kemp in this case, then the DMZ VIP.
cswebint = you internal DNS A record for Lync Web Services. This would point to you internal VIP.
4. LyncDiscover
This should be an external DNS A record pointing to your reverse proxy, which is the same external VIP as cswebext.
Hope this helps,

Lync 2013 standard number of Backends required and pool paring setup?

Hi
I am in the process of putting together a lync 2013 implementation. The plan is to use lync 2013 standard as IM and Presence are the only requirement we have approx. 3000 users
we have two sites
Site A (Primary)
x 2 FE-A1 FE-A2 Lync 2013
x1 BE-A1 Lync 2013
Site B (D.R)
X 2 FE-B1 FE-B2 Lync 2013
X1 BE-B1 Lync 2013
what I want to know is
1. If Site A has two FE servers each will require there own pool if I pair FE-A1 with FE-A2 can I also pair FE-A1 with FE-B1 and the same for 2?
2. Can the servers FE-A1 and FE-A2 use the same BE server or should I be using a separate server for each?
3. In this design I was thinking of using two edge servers 1 at each site that would be published using TMG, would this be correct, this would be for IPhone mobile users to use.
thanks in advance
J

1) If site A has to FE servers, and you go with Standard edition, they would be their own pools. If you wanted HA you could put three enterprise servers together into a single pool and load balance them. If you pair FE-A1 with FE-A2, those
two pools cannot be paired with any other pool. You also can't Pair FE-A1 to FE-A2, then FE-A2 to FE-B1.
2) Your diagram looks like Lync 2013 for the back end, it would actually be SQL, and this would specifically apply if you're using Lync enterprise. If the Lync front end servers are in the same pool, they can use the same backend, if they're not they
need separate back ends.
3) Edge servers would be published with a standard firewall, if TMG is your firewall that would work. If TMG is only being used as a reverse proxy, you would use it to publish your web services on your front end servers. Either way, you'll need
to also publish the web services on your front end servers to the Internet for mobile clients to function.

Lync 2013 updating databases after updating Front End servers

We have a front-end server pool consisting of 3 Lync 2013 servers and a back end of 2 SQL servers using SQL mirroring. All servers are Windows 2008 R2.
Following the instructions in
http://support2.microsoft.com/kb/2809243 , I verified that the servers were all ready for updates, then I ran the
Stop-CsWindowsService -Graceful cmdlet to stop the Lync services on the first FE server, then I ran LyncServerUpdateInstaller.exe to install the updates. After the updates were installed, I restarted the server, waited for Lync services
to all start, then repeated the process on the next 2 servers in turn. This was all successful.
I am now looking at step 2 in this document, applying the back-end database updates, and I have a problem and some questions. The problem is that all the databases had the principal copy on the mirrored SQL server. I ran the recommended Invoke-CsDatabaseFailover
-NewPrincipal Primary cmdlet repeatedly, using all the database types I could find, but I still have two databases (database names
xds and lis) on the mirrored server. Since the cmdlet requires a database type, what type of databases are the xds and the lis databases?
Once I get that done, I an still unsure of exactly what to run to update the databases. The KB article states to run Install-CsDatabase -ConfiguredDatabases -SqlServerFqdn FEBE.FQDN -Verbose .  Do I type this in exactly
as stated, or is FEBE.FQDN a variable for our SQL server or some other entity in our environment? If I do use the actual SQL Server name in that, do I run it twice, using the name of the mirrored SQL server the second time?
Thank you very much for your help.

Hi Logan Burt,
Central Management store database files
Data file or log purpose
                Xds.ldf
Transaction log file for the Central Management store
                Xds.mdf
Maintains the configuration of the current Lync Server 2013 topology, as defined and published by Topology Builder
                Lis.mdf
Location Information service data file
                Lis.ldf
Transaction log for the Location Information service data file
And you could verify if Lync Server 2013 database updates have completed successfully.

Outlook 2010 contacts not showing phone number in Lync 2013 client

Hi,
We have Lync 2013 with Exchange 2010. Recently we started upgrading Lync clients from 2010 to 2013.
A few users started reporting that their local Outlook contacts does not show phone numbers in Lync 2013 (working with 2010)
I have installed the august patch which should solve this issue
981751 - Lync 2013 does not display telephone number of an Outlook 2010 contact in the contact card
Any idea where to look next?

Hi Tobias Borgen Nielsen,
Lync expects all the phone numbers to be in the E.164 format, meaning they should be +1-111-11111111 etc. If they’re not like this, you will have to normalize them if you want Lync
to publish them.

What is best recommendstion for DNS LB for lync 2013 Edge servers

What is best recommendation for DNS LB for lync 2013 Edge servers ?. We have F5 LB for edge and want to decide if we can go with DNS base LB for Edge servers.
Anil MCC 2011,ITIL V3,MCSA 2003,MCTS 2010, My Blog : http://messagingschool.wordpress.com

It will be better to Use Hardware Load balancing (F5).
If you choose to use DNS load balancing for a pool but still need to implement hardware load balancers for traffic such as HTTP traffic, the administration of the hardware load balancers is greatly simplified. For example, configuring the hardware load balancer
will be simpler as it will only manage the HTTP and HTTPS traffic, while all other protocols will be managed by DNS load balancing

CMS Migration - Lync 2010 to Lync 2013 & Pool Pairing

Hi all,
Question regarding CMS installation when migrating away from Lync 2010.
Here's a brief overview of topology
- Lync 2010 Pool in Data Centre 1
- Lync 2013 Pool #1 in Data Centre 1
- Lync 2013 Pool #2 in Data Centre 2
- Lync 2013 Pools are paired
Consider the following
- CMS located on SQL Backend server for Lync 2010 Pool
- CMS database installed on SQL Back end for Lync 2013 Pool #1. CMS is moved to this location
Now for correct pool pairing and failover capabilities I would assume that
- CMS database needs to also be installed on SQL back end for Lync 2013 Pool #2
Once this is done then Lync 2013 Pool #2 Front Ends should replicate back into the CMS stored on the back end SQL database for pool #2? Nothing else would need to be done? As soon as it's installed its now a backup?
If I'm reading into this correctly the following from TechNet is basically telling me to do this?
When you establish a pool pairing that includes the pool hosting the Central
Management store, a backup Central Management store database is set up in the
backup pool, and Central Management store services are installed in both pools.
At any point in time, one of the two Central Management store databases is the
active master, and the other is a standby. The content is replicated by the
Backup Service from the active master to the standby.
Thanks,
paul.

Correct, when you enable pool pairing on Pool A - if it's a CMS server - it will prompt you to create the CMS database on Pool B. If you move CMS into a pool that is already pool paired, my experience is that CMS doesn't get created on Pool B because the
creation only happens during the pool pairing setup. Thanks -Richard

Exchange 2013 SP 1 + Lync 2013 CAS servers 100% CPU Load.

Hello. Can somebody explain about one issue?
We have Exchange 2013 CU6 + Lync 2013 (5.0.8308.556) integration. After install Exchange SP1 all Client Access Servers begun to consume all CPU time. In process
explorer there are w3wp.exe (MSExchangeServicesAppPool) and lsass.exe (netlogon context). In IIS logs a lot of events about

IIS logs are grow up very quickly, about 1GB per day. Before to installing SP1 was not problems. Thanks in advance.

Hi,
From your description, you said that you have Exchange 2013 CU6 + Lync 2013 (5.0.8308.556) integration, then you install Exchange 2013 SP1 on all CAS servers.
Do you mean your Exchange 2013 Mailbox server is CU6, and all CAS servers are SP1?
We had better have the same version on Exchange servers in our environment, if that is the case, please upgrate all to CU6, Exchange 2013 latest version, to check result.

Topology not replicating to Lync 2013 Edge servers

Hello all,
I have installed Lync 2013 with a FE Pool (three servers HW Load Balanced), Director Pool (two servers HW Load Balanced), and an Edge Environment (2 servers, in DMZ, member of a work group, also HW load balanced). All servers are Windows 2012
server (not R2).
I am able to login remotely and have green checks across the board at
https://testconnectivity.microsoft.com. So things are looking good.
My issue is that I am unable to replicate to my Edge servers from the FE. I am not seeing errors in the event viewer, just a big red 'x' on the topology tab in the control panel for the Edge servers. Also, when trying to force replication
the Edge servers continue to show 'False'.
Here are things I have done/checked to resolve this - so I need your assistance please:
1. From the FE, I can visit
https://EdgeFQDN:4443/replicationwebservice - there are no errors, no certificate errors so things look good
2. I have verified that I the Edge servers have the domain suffix added to them. The HW Load balancer is configured as the EdgeInternal.domain.com entry and the physical edge servers are named Edge01 and Edge02 (obviously with the domain suffix added).
So this seems correct based on recommendations.
3. I have added the following reg keys to all Lync Servers in the org
HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL ->DWORD ClientAuthTrustMode Value=2 and SendTrustedIssuerList DWORD Value: 0
I am trying to avoid having to resort to this as possible resolution -
http://ucken.blogspot.com/2012/04/resetting-lync-cms-replication.html, but if this is my next step, please let me know.
May be useless info, but here it is anyway....
One thing I will mention - during my setup, I setup Kerberos Authentication for Lync 2013. I followed
http://howdouc.blogspot.com/2011/07/kerberos-web-authentication-for-lync.html and
http://technet.microsoft.com/en-us/library/gg398976.aspx to configure this.
I am unable to access the RtcReplicaRoot\xds-replica directory on the primary FE server or any other lync server for that matter. I assume this is because it is locked down to the Kerberos account that
was created. However, I am unable to run the command "Set-CsKerberosAccountPassword -FromComputer FEFQDN.Domain.com -ToComputer EdgeFQDN.Domain.com". Obviously
this fails because the Edge servers are in a workgroup and cant see the Kerberos account that was created. Would this break the replication? Just thinking outloud...
Thanks in advance for any input.

Michael, Thank you for your response. We are currently in coexistence with a Lync 2010 environment.
Our environment consists of a European domain and a North American domain, both in the same forest. The European environment has had 2010 up and running for a couple of years and we (North America) just installed 2013 Lync. The EU domain has
many domain names they support (.uk, .net, .ie, etc.) NAm only manages .com domain name space.
I tell you this because I have configured the NAm environment to support only .com (save $ for SSL UCC licensing) and to provide separate paths to our services. There is a EU site and a NAm site in the Lync topology. The issues are with the FE
servers in NAm.
Based on your response above, the NAm servers are fine with your suggestions in #2 and #3. The CMS database is still on 2010 in the EU site.
Given that the NAm domain is configured to support only .com domain namespace, I am worried that moving the CMS to NAm FE's as it would break EU's ability for federation.
Any guidance or expertise is greatly appreciated.
My ultimate goal is to have NAm employees authenticate to their Edge servers in the site and EU to authenticate to their respective Edge Servers. Also, I have read that we can only have one Edge pool responsible for Federation in the Lync org.
I assume that we will have to keep federation going through EU as they have the SSL certs for all domains configured in their environment. Just a little confused before I make any changes.

Lync server 2010 and 2013 coexistence replacing edge servers

Hi all,
here is Our current deployment:
Lync server 2010:
1 edge
1 FE
3 branch sites
1 Monitoring server
Lync server 2013:
3 FrontEnd
2 Edge
2 Mediation
3 Backend
Simple urls are still point to Legacy (2010) servers.
External settings of Edge 2013 servers have been define With different name (Access,WEB and AV) and DNS (internally and externally) is pointing to New 2013 servers (via KEMP and TMG).
ATM 2013 topology is using edge2010 server.
Seems like we have two options for replacing Edge servers,one is Rip and replace and the other one is side by side transition.
We would like to do rip and replace so we can keep old simple urls (so that we dont have to send notice to external partners about Our New Access edge info) and using 2013 edge servers for federation and keep users on 2010 servers,then move them in
a controlled way.
What is the best way to do this?
Thanks!

Hi,
From your description above, the purpose is no need to update the New Access Edge info to the external partners. So for those external partners who set federation type of “Allowed Partner Server”, you need to keep the SIP domain name and the Edge Server
FQDN the same as before.
So base on my knowledge, you need to plan a down time, and firstly cancel the federation route for the Lync Edge 2010 Server. Delete the Lync Edge 2010 Server and publish the topology. Then deploy the Lync 2013 Edge Server with the same FQDN with Lync Edge
2010 Server. Then enable federation for it and point to the Lync Server 2013 FE Pool.

Lync 2013- 4 FE servers-F5 HLB- migrating users from OCS-WMI error

There are 4 Lync 2013 EE FE's with an F5 HLB. 3 of the FEs are Windows 2012 R2 and one is Windows 2008 (this will be decommissioned).
Access the Lyncadmin/cscp web page works to migrate users from OCS to Lync most of the time. We noticed at times the following error message:
Move-CSLegacyUser: verify that WMI Provider is installed by running OCSWMIBC.MSI. For details, see the inner exception.
So for troubleshooting we would use the <FEname>/cscp to test each server. The 2008 and one of the 2012 servers worked fine. The other 2 2012 servers failed with that same error message.
I looked at lots of articles and made sure that all of the servers had the HKLM\System\CurrentControlSet\LSA\DisableLoopbackCheck set to 1 as well as putting the Poolname FQDN and LB VIP IP address in the HKLM\System\CurrentControlSet\LSA\MSV1_0 registry
keys. Just the pool FQDN alone was tried as well. All the servers were rebooted one at a time as well after these changes. The Pool FQDN is a DNS entry with the VIP address.
The same user account is being used when logging into the CSCP. Trying the CSCP from any server or client machine and using the <FEname>/cscp fails for the 2 servers.
I have checked the authentication methods in IIS for CSCP internal and have negotiatekerberos then NTLM listed under Windows authentication\challenge.
I am running out of resources and ideas.
Anyone?

Have you confirmed that ocswmibc.msi is installed on all the 2013 Front Ends?
"First install the Windows Management Instrumentation (WMI) Backward Compatibility interfaces package; this application is installed
by running OCSWMIBC.msi. (OCSWMIBC.msi can be found on the installation DVD in the Setup folder.)" - http://technet.microsoft.com/en-us/library/gg413025.aspx
