Lync Server 2010 will not be supported on SQL Server 2012

March 16th, 2012 No comments

A blog post has been published by Damien Caro (a Microsoft IT Pro evangelist based in Paris) on his TechNet blog dispelling rumours and uncertainty around whether Lync Server 2010 will work with the newly RTM’d SQL Server 2012

Damien writes:

“There are some excellent reasons for willing to use SQL 2012 with Microsoft Lync like the support of the new availability model (Always On). However, Lync 2010 is using a feature called DMO (Distributed Management Objects) that was introduced in SQL 7.0 (a long time ago !).

SQL 2012 does not support this feature anymore as it is indicated in this article : so SQL 2012 will not be a supported platform for Lync 2010 as it is now.”

    Office 365 quick config for Lync Mobile

    January 5th, 2012 No comments

    If you want to have a play with the new Windows Phone client (WP7) for Lync then Microsoft haven’t quite setup the DNS records yet (or they are still propagating round the internet). Not to worry you can force it by manually specifying some URL’s…

    If you’re using your own domain with Office 365 or on one of the higher plans check these guides… Set up Lync mobile devices and Set up your network for Lync Online.

    Start the Lync mobile client

    Enter your username as: <name>@<domain>

    Enter your password:

    Specify a username in the same format: <name>@<domain>

    Toggle the “Auto-detect services” & enter the following as the “External Discovery URL”

    Chances are you’ll never be “internal” to the Office 365 network so we can probably leave the internal one clear for now..!

    It looks like some clients don’t work if you don’t give them an “internal URL” too, so just repeat the process for the Internal Discovery URL:

    You should now be able to connect & enjoy having a play around.

    Prepare AD, Install Topo and define a Front-End pool

    August 12th, 2011 No comments

    After preparing the environment we are ready to start the installation of Lync 2010.

    Please keep in mind that the names and ip’s are fictive in this documentation.

    In this setup I choose to install Archiving and Monitoring on seperate hardware. Also keep in mind that you first have to prepare thes servers the way I described in part 1.

    If you need more information or if you have questions please send an e-mail to and I will reply or help you as soon as possible.


    Prepare Active Directory Domain Services for Lync Server 2010

    The next area for preparation is Active Directory Domain Services. Preparing AD DS for Lync Server 2010 consists of three steps:

    · Schema Preparation

    · Forest Preparation

    · Domain Preparation

    Each of these steps can be performed by using the Lync Server Deployment Wizard or the Lync Server Management Shell cmdlets directly.


    Install Topology Builder and define Topology for Lync Front-End Pool

    Now we have all of the infrastructure preparation complete, so it’s time to move on to defining the topology for Lync 2010 Enterprise Edition in Topology Builder.

    1. Log on to Lync Front-End server

    2. Go to Start, click All Programs, click Microsoft Lync Server 2010, and then click Lync Server Topology Builder.

    3. On the Topology Builder dialog box, select the New Topology option, and then click OK.


    4. On the Save New Topology As dialog box, enter a name in the File name field, and then click OK.

    Lync 2010 Enterprise Edition Installation

    August 9th, 2011 No comments

    This guide will run through a consolidated Enterprise edition install (without voice gateway integration, whereby all roles will be deployed on virtual machines.

    The guide will be split up in different chapters.

    The first chapter is all about preparing your Lync 2010 environment.


    Prepare the Lync 2010 Enterprise Edition Server Infrastructure

    The following sections outline the step to prepare the Lync 2010 Enterprise Edition server infrastructure.

    1. Set Up Enterprise Edition Hardware and System Infrastructure

    2. Install Prerequisite Software

    · Lync Server requires Microsoft .Net Framework 3.5 with SP1.

    · Prerequisite software for database servers.

    · Message Queuing. Message Queuing (also known as MSMQ) role components and Directory Service Integration should be installed on the Front End Server, the Archiving Server, and the Monitoring Server if you plan to deploy the Lync Server 2010 Archiving or Monitoring Server roles. The Message Queuing components can be found in Server Manager or can be deployed by using servermanagercmd.exe or the Add-WindowsFeature Windows PowerShell cmdlet.

    · Configure IIS:

    Role Heading

    Role Service

    Common HTTP features installed

    Static content

    Common HTTP features installed

    Default document

    Common HTTP features installed

    HTTP errors

    Application development


    Application development

    .NET extensibility

    Application development

    Internet Server API (ISAPI) extensions

    Application development

    ISAPI filters

    Health and diagnostics

    HTTP logging

    Health and diagnostics

    Logging tools

    Health and diagnostics



    Anonymous authentication (installed and enabled by default)


    Windows authentication


    Client Certificate Mapping authentication


    Request filtering


    Static content compression

    Management Tools

    IIS Management Console

    Management Tools

    IIS Management Scripts and Tools

    · Install the Remote Server Administration Tools

    · Install Silverlight

    Silverlight is required to run the Lync Server Control Panel. Although we won’t be using the Control Panel until everything is installed, you can install it now since we’re installing the prerequisite software. Silverlight needs to be installed on the Front-End servers.

    · Install and Configure SQL Server

    Lync Server 2010 leverages SQL Server for the back-end database and the Archiving and Monitoring databases. SQL Server needs to be installed before we can install Lync Server 2010. For this lab, SQL Server 2008 with Service Pack 1 will be used, and installed on the Back End Server as well as the Monitoring/Archiving Server.

    3. DNS records

    Lync Server 2010 leverages DNS for various features. Certain DNS records are required as part of the infrastructure preparation. Each server within this lab will already have an A record in DNS. This is attributed to the fact that I am using Active Directory-Integrated DNS, which has Dynamic DNS enabled by default. However, there are additional DNS records that are required before we proceed, including:


    IP of Front End Server


    IP of Front End Pool


    IP of Front End Pool


    Port: 5061

    4. Grant Administration Permissions

    Follow these steps to grant Administration permissions:

    1. Ensure you are in the Users Container in Active Directory Users and Computers.

    2. In the details pane, locate the CsAdministrator group, right-click on it, and select Properties.

    3. On the CsAdministrator Properties page, click on the Members tab.

    4. Click Add.

    5. On the Select Users, Contacts, Computers, Service Accounts, or Groups dialog box, type Administrator in the Enter the object names to select field, and then click OK.

    6. On the CsAdministrator Properties page, click OK.

    5. Create the Lync File Share

    The user account that we will use to publish the topology must have full control (read/write/modify) on the file share in order for Topology Builder to configure the required permissions. Because I’m going with an Enterprise Edition deployment, the file share cannot be located on the Front End Server. As a result, We prefer to create the file share on the Monitoring/Archiving Server.

    Log on to Lync Monitoring/Archiving server

    2. Go Start, click Computer, and then click Local Disk (C:).

    3. Right-click in the Details Pane, select New, and then select Folder.

    4. Name the new folder LyncShare.

    5. Right-click on the LyncShare folder, select Properties, click on the Sharing Tab, and then click Advanced Sharing.

    6. On the Advanced Sharing dialog box, select the Share this folder option, leave the Share Name field as LyncShare.

    Lync 2010 NTLM Client Authentication Mismatch

    August 1st, 2011 No comments

    After installing Lync at one of our customers we experienced the following problem when the user was trying to log in.

    When I try to make the remote sign-in with the appropriate credentials, Lync reports me “Cannot sign in to Lync. Lync was unable to sign in. Please verify your logon credentials. But it only happened on Windows XP/Windows 7 machines.

    When I try to sign-in using the same credentials and Windows 2008 R2 as the client, Lync is signin in!

    TheLync server was running Windows 2008 R2. With Windows 7 and Windows 2008 R2, 128-bit encryption is (by default) required for all NTLM authentication requests. After disabling the 128-bit encryption requirement using information from and running a gpupdate the computer was able to authenticate successfully.
