Is anyone has installed latest Lync Server 2013 CU on HPv2

Hi,
Is anyone has installed latest Lync Server 2013 CU (http://support.microsoft.com/kb/2809243) on HPv2.
my concern is, if this CU is also applicable to HPv2. because the KB says installation on Enterprise and Standard editions of lync, but no where it is mentioned about HPv2.
Thanks

As far as I know, it is not applicable.
The installation media of Lync Server 2013 Multitenant Hosting Pack includes a tool for applying patches to the Lync Server software, \amd64\LyncServerUpdateInstaller.exe.

How to run a Lync Server 2013 in amazon ec2 Instance ?

Hi Friends,
I would like to install a Lync server 2013 in amazon ec2 instance. Let me know can i install Active Directory server, Lync Server 2013 and Media server in a single amazon instance ?. If it possible how can i do it ?. And is any other features need to install
to get the fully functional Lync server. Please help me am newbie in Lync environment

You can get Lync working in EC2 and I have lab'd his many times. Having said that the process isn't that straight forward (especially if you plan to do voice) a lot of planning and testing, specifically of the network would need to be undertaken.
You can add multiple interfaces to an EC2 instance (see here http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-eni.html)
If you're hard set on using EC2 you can get it to work, but I personally would look at Office 365 E4 or a small on-premise deployment depending on your requirements.

Lync Server 2013 Installation Error

Hello,
I am using my AD in Windows Azure VMs. I created new VM of A3 (4 cores, 7 GB Memory) Windows Server 2012 R2, Port 1433 MSSQL added, made it a member of Domain and planned to install first Lync Server 2013 on it.
In "Setup or Remove Lync Server Components" of "Install or Update Lync Server System", got an Red Coloured text "An error
occurred while applying SQL script for the feature BackendStore."
I have not enabled monitoring and archiving server in topology builder. I added "Network Service" and assign "Full Control" in Security Permissions of "C:\CsData" and "C:\LyncShare".
I executed the SQL Setup Wizard and upgraded any instance to 2012.
Please guide.
Thanks, Divyaprakash Koli

Is the Lync deployment in Azure as well? If so please check this

The Director role is optional in Lync Server 2013 - could anyone please explain why the director server has lost its importance??

Could anyone please explain why the director has been removed from spotlight as it had much importance in LYNC 2010 and now being an optional role in LYNC server 2013.[any call flows regarding director servers would be much useful]

Hi SJ Praveen,
A Director is a server running Lync Server 2013 that authenticates user requests, but does not home any user accounts. Lync 2013 Front End servers have the same registrar service and functionality
as the Director.
The Director isn't providing any special functionality. If the Director goes down, all pools would become inaccessible when the clients queried DNS for the SRV record until an administrator
makes a manual internal DNS change that points users to a Front End pool to handle the sign-in request from Lync clients. Microsoft has made the Director functionality relevant for organizations that have specific security requirements, such as allowing all
external users to register to a specific internal server instead of the Front End servers. This server role is merely optional and not needed for most Lync Server 2013 deployments.
Best regards,
Eric

Telephone numbers (officePhone and homePhone) are missing in a contact card in a Lync Server 2013-based Lync mobile client

In my opinion, the error has not completely fixed in KB2967628. After I install the latest November 2014 cumulative
update. I see the following behavior. User A searches for user B. User B never sign in to the Link. There are three fields in the active directory for User B: officePhone, mobilePhone and homePhone (these fields contain different numbers). When searching on
the mobile client (Android/IOS) for user B – as result user A see only mobile number. If User B At least once will go to Link (sign in) when his search will work, (find officePhone). If User B will change, the privacy settings for user A is in the search will
be displayed homePhone field.
On the Desktop client,
I can find all the fields without those actions performed in the example. If I make a request
to the service UCWA manually like this (below
the text) before
actions, which I performed in example, I did not receive officePhone and homePhone – only mobilePhone field.
GET "https://lync.domainname:443/ucwa/oauth/v1/applications/XXXX/people/search?query=$usename$&limit=200" -H "Content-Type: application/json" -H "Accept: application/json" -H "Authorization: $USENAMETOKEN$"

Hi,
Based on your description, I’m sorry I’m a little confused about the following you mentioned. I understand the issue is we can only see the mobile number in the contact card on Lync mobile client and that we can search for users based on their office number,
we can see the home phone field in the contact card but there isn’t number showing. I anything I have misunderstood, please feel free to let us know.
“When searching on the mobile client (Android/IOS) for user B – as result user A see only mobile number. If User B At least once will go to Link (sign in) when his search will work, (find officePhone). If User B will
change, the privacy settings for user A is in the search will be displayed homePhone field.”
According to the KB29677628, this issue is caused by UCWA only sending the work number, and we need to install the update for web components server
http://support.microsoft.com/kb/2967628/en-us
August 2014 Cumulative Update 5.0.8308.738 for Lync Server 2013, web components server

Lync Server 2013 in a Remote Desktop Environment

Hello Community,
We have a client who is sold on Lync. He wants to install Lync server in a Terminal Server but his environment is RDHS 2008v2 and his end users have thin clients. According to MS official position It is not supported. Has anyone successfully implemented
this ? If yes what are the pitfalls that lay ahead with regards to audio/video redirection, desktop sharing etc. He has traditional phones but really he wants to get rid of them and go Lync full blown.

The Virtualizing Lync Server 2013
(WindowsITPro) article presents a nice overview to this topic.
In additon, do take a look at the following resources which may be helpful:
Planning a Lync Server 2013 Deployment on Virtual Servers
http://www.microsoft.com/en-us/download/details.aspx?id=41936
Deploying the Lync VDI plug-in in Lync Server 2013
http://technet.microsoft.com/en-us/library/jj204683.aspx
Making the Microsoft Lync to work best in your virtualization environment
http://www.youtube.com/watch?v=WiZX3uoVKV8
Note that unlike Lync Server 2010, the Lync 2013 VDI browser plug-in is designed to support VDI environments (with paired audio/video) running on supported platforms (from Windows Server 2008 R2 to 2012/R2).
Hope this helps.

Office Web Apps server / Lync server 2013

Hi I have installed a Lync 2013 Server and Office Web Apps Server. Configured Lync topology, Office Web Apps farm and certificates.
However when i start the services i get this error message in the log saying Office Web Apps discovery failed.
Event ID: 41033
Description:
Office Web Apps Server (WAC) discovery failed, PowerPoint content is disabled.
Attempted Office Web Apps Server discovery Url:
Received error message: Invalid Uri syntax for WAC configuration
The number of retries: 1,
Cause: Office Web Apps Server may be unavailable or network connectivity may have been compromised.
Resolution:
Check HTTPS connectivity from this box to the Office Web Apps Server deployment using the discovery Url.
I can access the OWAS server Url from Lync Server
Connecting to the HTTPS discovery URL is working fine, and brings up the XML-page (after i click "show all content").
The two servers are located on the same internal network, DNS resolves fine both ways, and no firewall rules blocks any connections between the two. Can anyone please help me figure this out?
Only identical problem found online is here (Invalid Uri syntax for WAC configuration):
http://blogs.technet.com/b/dodeitte/archive/2012/09/10/office-web-apps-server-amp-lync-server-2013.aspx
He resolved the problem by assigning a new OAuthTokenIssuer certificate. This however did not fix the problem in my case.
Regards
Sverre A. Veel

Hi,
In addition, please make sure you have restarted front end and office web apps server after reissuing the certificate.

The Real Problem is that my Lync HP 4120 Phone can't make a sign in, not from USB cable loging, nor with PIN authentification
When I try to make a login with the USB cable, I set the user and password and the phone says "Connecting to Lync".. "Downloading a certificate" ... "Installing certificate"... "Downloading Certificate"...
"Installing Certificate".. forever
When I try to make a login with PIN Authentification, the phone first displays the following:
Account used is not authorized, Please Contact your support team and then shows this:

The Pin authentification is enable

Clean up Active Directory after dirty deleted lync server 2013

Hi All,
i have trouble with my lync server, im gonna re-deploy my lync server 2013 after it has deleted without no purpose.
based on my experience if we want to deploy with the same name and configuration like previously. setup with failed because it has already register in adsiedit ?
please tell me how to clean up my AD.
thanks for you assistance guys,
Best Regards,

Hi,
On DC, please run adsiedit and connect to the Configuration naming context.
Browse down to Configuration > Services > RTC Service and then just delete the entire
RTC Service container. Also delete the Computer object(s) for any Lync Server you had previously installed. Then you can install the new Lync Server 2013 with no issue.
Here is a similar case may help you:

How to achieve Multi-Tenant in Lync Server 2013 Enterprise Edition

Hi,
As LHPv2 is discontinued, is anyone has idea how to achieve Multi-Tenant in Lync Server 2013 Enterprise Edition?
e.g users from different tenants should not be able to communicate unless it is allowed either by federation or any other form.

once a Topology has been published you can not change the FQDN.

SQL Server Sizing for Lync Server 2013

Hi,
We are planning to install Lync Server 2013 with 800 users, but I can find any information about the SQL Server instance sizing.
Can anyone give me an estimation or prior experience with similar installations? I need to know Disk size, memory an CPU number.
Thanks in advance.

There are a few variables to consider. Are you turning on monitoring, archiving, and is enterprise voice enabled? Is persistent chat enabled? Is it virtualized? Is this Lync enterprise edition or standard with a portion of the
databases hosted on full SQL? Are you required to retain any information or logs for a specific amount of time? Are you keeping SQL backups local with maintenance plans and for how long?
I would suggest not going below 16GB for a SQL Server, but you may not need much more. If it's virtual I'd throw 4 cores at it at least and disk space will vary based upon what you're doing and how long you want to keep things. Thick provision
those drives and make sure the logs and databases are on separate partitions.

The problem is with Persistent Chat. It works perfectly with the 2013 desktop client but - whilst 2010 Group Chat connects - I receive the error message "The [LOGON_DOMAIN] is not available". No chat rooms are available and I am unable to search.
I have been unable to locate anything on the web which discusses the problem.
I do not know whether this makes a difference but the 2010 clients use terminals rather than dedicated workstations.
Can anyone shed any light on what the problem may be?

Have you created a CsPersistentChatEndpoint to allow the Group Chat client (2010) to connect to Persistent
Chat server? Please take a look at: http://technet.microsoft.com/en-us/library/jj204901.aspx

Please help me resolve the Lync server 2013 deployment error: "An error occurred while applying SQL script for the feature BackendStore."

I am getting an error in "Step 2 - Setup or Remove Lync Server Components" of "Install or Update Lync Server System" step.
"An error occured while applying SQL script for the feature BackendStore. For details, see the log file...."
Additionally, all previous steps such as: Prepare Active Directory, Prepare first Standard Edition server, Install Administrative Tools, Create and publish topology are done without any errors. The user that I used to setup the Lync server is member of:
Administrators
CSAdministrator
Domain Admins
Domain Users
Enterprise Admins
Group Policy Creator Owners
RTCComponentUniversalServices
RTCHSUniversalServices
RTCUniversalConfigReplicator
RTCUniversalServerAdmins
Schema Admins
I have tried to re-install all the things and started to setup a new one many times but the same error still occurred. Please see the log below and give me any ideas/solutions to tackle this problem.
