It seems that everything is working, but I have many errors in Event Log.

Cause: Autodiscovery Uri was not correctly configured or unreachable, that there is a problem with the Proxy, or other errors.
Resolution:
Check event details.  Check autodiscovery Uri is properly configured and reachable. Check that proxy setting is properly configured and reachable.  Validate Lync to Exchange Autodiscovery configuration by following the trouble shooting guide. If problem persists, notify your organization's support team with the event details.

***************************************************************************************

Not sure why it is trying to use https://autodiscover.domain.com/autodiscover/autodiscover.svc. Is this correct?  I thought it should behttps://lyncdiscover.domain.com/autodiscover/autodiscover.svc orhttps://lyncweb.domain.com/autodiscover/autodiscover.svc.

If I run Get-CsService -WebServer | fl  autodiscover*, I receive the following output:

AutodiscoverServiceExternalUri : https://lyncweb.domain.com/Autodiscover/AutodiscoverService.svc/root
AutodiscoverServiceInternalUri : https://lyncpool.domain.local/Autodiscover/AutodiscoverService.svc/root

As I said, everything looks good and working. Anyone has any ideas what that is?

Thank you.

Thank you. Eric.

I think I asked this before but here it goes again if I did. Is there any down side to not enabling Kerberos authentication for Lync 2013.

Getting the dreaded "Warning:Pool fully qualified domain name (FQDN) "lyncpool.domain.com" is not found as a http service principal name (SPN) on any user or computer. Kerberos web authentication is not configured.." when I run the BPA.

I found some article that describes this exactly and it goes into some detail about enabling Kerberos. Seems like a lot of work and potential for something to break. Is it ok to just stick with NTLM?

We have 3 FE servers in a single pool with one PC server. Our Edge is 2010 but we are upgrading to 2013. I still have one 2010 FE but no one is on it.

Hi Everyone,

We are designing a Highly Available solution of for LYNC 2013 and planning to add a witness server to the backed SQL server.

Following are my Queries.

1)For the witness server should the SQL server be dedicated to the LYNC infrastructure or it can be used to host other databases.

2)I am assuming the Witness Database should be in the same Domain?

3)What is the version of the SQL server that is supported as the Witness server, can this be the Free SQL express edition ?

Waiting for some replies :-)

Hi everyone,

Our front-end pool will consist of 2 front-end servers for high availability. One front-end server should support 10,000 users, but since the recommendation for a front-end pool is 3 servers, i want to know if deploying only 2 could be a real issue. What I understand from the Technet documentation is that the way user data is stored (1 primary copy and 2 backup copies) is one reason (but I would thing not enough reason for us as a company of 1200 users) and that you need to shutdown and bring them up again in a specific order. Am I missing something what would definitely make me deploy 3 front-end servers? 

Hi

We are adding a new Lync pool in our organization where Lync is in a resource domain and Exchange in the account domain

Lync & Exchange integration (OWA & UM) is already in place, I would like to know when adding the new Lync pool is there any configuration to do on the Exchange side so that the integration also functions for the new Lync Pool ?

Thanks

Luca

I did all of the latest windows updates as well as the Sept CU for Lync 2013.

Any ideas?

Thanks.

I have run the follwoign and it gave no results back:

 Get-Childitem cert:\LocalMachine\root -Recurse | Where-Object {$_.Issuer -ne $_.Subject} | Format-List *

System was migrated from Lync 2010, but that has now been removed from topology.

Any other ideas?

Hi,

Our organisation is in the process of changing gateway providers, so we have to move our currently deployed Lync 2013 Edge Server and TMG (Lync related sites) to the new provider datacentre. We have new public and DMZ IP addresses allocated for these services and we can't use the current addresses.

Has someone been through this and is there a best practice to follow to transition these services with minimal outages to the users?

Any help would be appreciated.

Hi guys,

I have a client with multiple sites, a large number of remote workers (on and off domain) and Lync Phone Edition devices.

We want to deploy a custom music on hold file. What's the best way of doing this? I'm thinking

• Placing the file on a share on one of the Lync servers. However this would mean (I assume) that clients will always try to contact the UNC path every time a call is placed on hold, which would result in site B connecting to site A for it's MoH file. This is very inefficient and adds delay onto placing a call on hold. If accessing the file from a central share is best practice, how could I do this per site? Site policies I've tried haven't worked very well. For example, if a file is on\\serverB\MoH\file.wma for a site called "London Site" what commands do I need to run to create a policy that will force clients located at a site to use that UNC path? Also, how do client know what site they are in?

• Alternatively, I was thinking of pushing out the WMA file to local devices via a Group Policy, and then setting Lync globally to point to %systemdrive%\MoH\file.wma. Again, how do I go about doing this? Also, what would happen to LPE devices that wouldn't have the file (as they wouldn't get the GPO)?

Any help with this would be appreciated. Particularly around how users are assigned to sites, and the syntax used to create a site policy for the first option. Any best practice guidance would be great!

Thanks - Steve

I have the settings set in Lync 2013 control panel to enable purging of archive data after the data has been exported only.  However after I run the powershell commands to export the data the data remains yet.  Is there a powershell command that I can run after the export to manually delete the archive data I just got done exporting?

Hi team,

I read that the best way for a HA topology is to go ahead with 3 FE server pool(Although MS has said it's workable, many recommend not to). Now this leaves me with another problem, can I go ahead with just 1 SQL Back-End server. I know in this case SQL will have no failover. But if we ok with the downtime, will it work properly when the BE is up?

The front-end includes the following:

• Basic Lync functions
• Mediation
• Monitoring
• Archiving

Thank you.
Chris!

Hi

We have a problem that i have used a whole day trying to solve, however i have not been able to find a solution. So now i'm hoping that someone here can help me.  :)

We have a simple workflow with 3 options. At first the problem was that at seemingly random times it gets redirected to a random option. Later we found out that we could provoke the problem by making noise into the microphone. So it must be the speech recognition that picks up the background noise from the microphone and then redirects to what it thinks the user said.

So the question is, do anyone know how to disable speech recognition in lync 2013 workflows? I have not been able to find a solution or anyone with the same problem.

Thanks in advance

So I have my edge server set up in the DMZ. 3 ips bound to an interface for external connectivity.

sip.domain.org (A record)
webconf.domain.org (A record)
av.domain.org (A record)

_sip.tls.domain.org:443 pointing to the same IP as sip.domain.org
External Lync Clients should be using this srv record to auto-connect, correct?

I have purchased a thawte ssl cert and bound it correctly to the external interface.  Internal interface is a PKI internal CA cert. Sometimes when doing a testconnectivity from MS, it comes up stating " The certificate couldn't be validated because SSL negotiation wasn't successful", when other times I run the test and it states that it validates the cert correctly, analyzing the cert - no problems found, etc, all looks good and then fails at "couldn't sign in Error Unknown (0x80131500)  Error type: TLSFailureException.

Not sure where to start looking or why it shows the cert is good sometimes and others not.

Also when I launch the Lync Server Admin Console, Under Topology,  my edge server is showing Replication with a red X.  Don't know what to look for either.

Hello,

I was hoping someone can point me to a proper download for the Lync 2013 Web App Plug-in for Windows XP? We are attempting to deploy the Web app to all of our machines including legacy Windows XP machines. So we can utilize the Lync meeting features but the installer you get when trying to join a meeting via the web on Windows XP is incorrect. Microsoft's site does show that Windows XP SP3 with IE 8 is supported as per their TechNet page.

http://technet.microsoft.com/en-us/library/gg425820.aspx

And while the download we get would appear to be correct for Windows XP  since it's named "LWAXpPlugin32BitInstaller.msi". When you attempt to install it you get an error that you are not running the correct operating system.

So it would seem like the Windows 7 installer was just renamed to appear like it was for Windows XP rather then a proper installer for it. We are currently running Lync Server 2013 version 5.0.8308.577.

Folks,

We are looking to migrate our OCS 2007 R2 Enterprise, to Lync 2013. 

We are running AD windows Server 2012 R2 functioanl level.

We have completed the schema,forest and domain prep for Lync 2013.

I have a few questions that you  guys may be able to answer.

1.)Can we upgrade from OCS 2007 R2 enterprise pool to LYNC 2013 standard pool.

2.)Is there any concise documents out there that document how to upgrade form OCS 2007 R2 to Lync 2013.

Regards

I have a Lync 2013 pool with databases on SQL 2012 with mirroring and a witness.  How do you guys with that type of setup handle Windows patching of the SQL servers?  Do you manually move the databases to the mirror node first with Invoke-CsDatabaseFailover,or do you just patch and reboot the Primary and let SQL handle the failover?

Can you leave the databases running on the Mirror for an extended period of time without any problems?

Hi,

We want to deploy Lync 2013 as a hosted solution in order to provide the ability to customers for EV as well as Audio / video calls and conferences.

What i remember is that Microsoft Lync 2013 hosted solution is deprecated and there is no more Lync 2013 hosted solution, is it true.

If it is true then what are the alternatives, we do not want to use Lync online as in our region Lync only EV is not possible.

Can we achieve this by installing Lync 2013 through simple setup but then which users do we have to give to users and what will be their sip domain name 

i believe in Lync hosted solution the Lync Active directory has nothing to do with the customer active directory is this correct or we do need to provide some kind of trust or communication between these two active directories

how Lync analogue phones which are at client side will connect to lync server (where Lync and gateways are deployed at our datacenter and analogue phones and faxes are at customer side) or we need to deploy some kind of ATA at each customer site, i have read technet article but i do not understand that it is achievable or not.

how Lync qualified phones will conenct to Lync server, will all Lync soft phones and polycom phones will connect over the internet

I am seeing the following error very frequently on all my Lync servers that are running the CLS agent:

LS Centralized Logging Agent Event ID 33041

It appears the errors started with the install of the August CU updating Lync to 5.0.8308.738.  Note, this error is with CLS, not Lync Debugging tools.  I have verified that ClsAgent.exe is using C:\Program Files\Common Files\Microsoft Lync Server 2013\Tracing\default.tmx, which is 23041 KB and dated 8/3/2014.

Anyone else seeing this?  Anyone have a fix?

Hello,

I'm trying to setup Lync 2013 on Windows 2012R2 

I have two virtual machines 

1. Domain Controller + Active Directory + DNS Server.  Hostname: dc, Domain name: lynctest.domain.local

2. The machine  I am attempting to install MS Lync on. This machine has been joined AD-domain mentioned above. Hostname: lyncfe, Domain name: lynctest.domain.local

At the moment I am at "Install or Update Lync Server System" step in Lync Deployment Wizard. 

I have successfully completed all previous steps. But then I get this warning (step 2):

...

Host name: lyncfe

WARNING! Host not found in topology. All roles will be uninstalled.

...

A lot of similar posts suggest to change DNS-suffix for Lync in order to match FQDN of Lync in topology.

But this is not my case, because  machine has been joined AD-domain.

I verified FQDN in topology - lyncfe.lynctest.domain.local. It matches hostname (lyncfe) + domain (lynctest.domain.local)

Anyway, I tried to set DNS suffix to lynctest.domain.local and wasn't even able to pass the 'Preparing active directory' step

Any suggestions would be appreciated
