    Lync Server 2013 Now Supported on Windows Server 2012 R2

    With the release of the Updates for Lync Server 2013: October 2013, Lync Server 2013 is now supported on Windows Server 2012 R2. 

    More Information Here:

    Background
    The Lync client integrates with Exchange Server to enable many features in the Lync Client.  Having both Lync Server and Exchange server really enables Unified Communications.  Based on the Exchange version you have different integration options.  Here are some examples of those integrations that only work when Exchange Webservices are discoverable and configured in Exchange:  Contact Information, Calendar Information, Conversation History, Missed Conversations, Missed Calls, Voice Mail Playback, Unified Contact Store, High Resolution Photo’s, …

    While this is great there is a difference in how Lync connects to Exchange compared to Outlook.

     

    Problem
    When customers want to add Lync to their application stack we have to make sure that the Exchange Autodiscover process works as expected.  Unfortunately Outlook and Lync do not use the same process to discover the Exchange Web Services when connecting from the Local Area Network (LAN).  Most customers don’t implement the Exchange Autodiscover process correctly.

    Outlook checks the Service Connection Point (SCP) in Active Directory first and uses this information to connect to the Exchange CAS Server, using this method there is a side effect that because it is an Authoritative Source for Exchange connectivity and the client will not prompt for any Certificates issues (by default Exchange uses a Self Signed certificate for the Web Services which you should change as soon as possible)

    Now adding Lync at the Customer puts some other requirements for the Exchange Autodiscover process.  The Lync client does not query the Service Connection Point (SCP) in Active Directory as outlined in the drawing below.

    image

     

    Autodiscover Process for Exchange Web Services by Lync (in specified order)

    1. https://<smtpdomain>/autodiscover/autodiscover.xml
    2. https://autodiscover.<smtpdomain>/autodiscover/autodiscover.xml
    3. http://AutoDiscover.<smtpdomain> /Autodiscover/Autodiscover.xml
    4. _autodiscover._tcp.<smtpdomain> (Autodiscover DNS SRV Record)

     

    Impact
    Because the Lync client only uses DNS to discover the Exchange Web Services and Outlook does not (internally) most customers have to change their Exchange configuration.  While most Admins do not configure Exchange Web Services correctly because not required by Outlook they have to reconfigure the environment for Lync.

    Solution
    Have the Exchange Admins configure the Exchange Autodiscover process correctly, not only for Outlook but also for the Lync client
    Reconfiguring Exchange involves a lot of steps; Changing Certificates, Changing DNS entries, Changing Exchange Configuration …  This is not something the Exchange Admin wants to do often and must be planned thoroughly.

    Workaround
    A workaround exists to configure both Outlook & Lync client to dismiss Certificate Warnings if DNS entries are added for Exchange Autodiscover and Certificates/Configuration cannot be changed on Exchange.
    The workaround is configuring both clients by GPO with specific registry entries to disable the Certificate Popups.
    While this is not an ideal solution it does work.

     

    Personal Thought
    Microsoft should make the Exchange Autodiscovery process transparent for both Outlook & Lync.
    Either make the DNS Entries mandatory or have Lync query the Service Connection Point in AD

    Microsoft released an out-of-band Security Advisory (2896666) today for an exploit that could allow remote code Execution. It is currently actively used in the wild but mostly in Asia (based on reports).

    Due to a vulnerability in the GDI library, which is used by Office and all Lync versions, a hacker could use a specially crafted Word Document to gain Remote Code Execution access to a machine running the affected software.

    A patch does not yet exist, but a workaround is available by disabling the TIFF codec in registry:

    To disable the TIFF codec:

    1. To add a registry entry, create the following registry subkey:

      HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Gdiplus

    2. Create a DWORD value for the TIFF code by creating a registry entry (DWORD value) under the registry subkey you created in step 1:

      DisableTIFFCodec

    3. To disable the TIFF codec, set value of the DisableTIFFCodec registry entry to 1.

    More information: Security Advisory (2896666)

    In general Lync is a very secure communication platform and this vulnerability requires uses interaction to be exploited. The exploit is not found in core Lync application code but in a library that is used by Lync.   It is not the first time that vulnerabilites are found in the GDI library, as you can see here: MS07-046MS08-021

    Update: Microsoft provided more information in this blog post and stated that so far Lync has not been targeted for exploit .

    Don't cry victory too soon as this is a very limited troubleshooting tool...
    If you need to do real troubleshooting then the Client Logs and Snooper & Fiddler are still your friend.

    Tyring to log into an un existing account just to try out the new Log option for Sign-In issues

    We get a default message box saying “Can’t sign in to Lync”

    Right-Click the Lync Icon in the Taskbar and Select “Sign-in Logs”

    You will find some more detailed information in here

    While there is more information available then before, this could be much better, it would be nice to clean up to have a more user friendly Sign-In log

    The Problem(s)

    Response Groups Service (RGS) is a built-in Lync Server application for automated call flows based on templates or custom designed PowerShell scripts.

    Despite it's good integration and decent amount of features, I believe it has a wide margin for improvement.  (Take a look at Lync Ideascale and you can see that with 95 votes it's currently the most requested improvement for Lync)

    That being said, today I got the following error when adding an existing Agent to an existing Agent group:

    After a restart of the RGS Windows Service I also found Event ID 31137 and 31138 from LS Response Group Service stating that it could not find an agent with SIP address XXXX:

    The Background

    Why does this happen? I knew that the SIP address of the Lync user has been changed after a SIP Domain change .

    To explain what is happening here, we have to dig into some RGS internals and explain some basics:

    1. Lync users handling incoming calls for RGS are called Agents
    2. Agents are grouped into Groups
    3. Groups are assigned to Queues
    4. Incoming calls are directed through a workflow and then forwarded to a specific Queue

    A Lync user is considered a RGS Group Agent when he is added to at least one Agent Group, but he can also be a member of many.  An administrator can assign a user to an Agent Group using PowerShell or Lync Control Panel

    The Deep Dive

    Now let's have a look how RGS handles this internally.

    The RGS application has two specific databases: rgsconfig and rgsdyn:

    The rgsconfig database contains the RGS configuration while rgsdyn contains "dynamic" data like current signed in agents and instances.

    Within the rgsconfig database we will find a table called Agents:

    The Agents table has the following structure:

    In troubleshooting this issue the following 3 fields are important:

    • ID: a unique GUID, specific to RGS database
    • UserSid: a unique Active Directory user identifier (user SID)
    • SipAddress: the Lync User's SIP Address

    Internally RGS works with the ID field when mapping Agent Groups to Agents as you can see in the table AgentGroupsToAgentsMap):

    When adding a user to an Agent Group, the Response Group service will check if the user already exists. The key for our problem is how RGS performs this lookup: based on what information?

    After studying it's behavior we can only conclude it does this based on the user SIP Address:

    1. After changing the SIP Address of an agent, RGS was unable to map the existing agent record to an AD object (see Event Log). 
    2. When adding the same user (with new SIP Address) to an Agent Group, RGS was not able to find the existing Agent record with the old SIP Address.
    3. Because it could not find the Agent record, it will try to add a new agent record into the table. This action fails because the AD UserSid must be unique and a record with the old SIP Address and same SID is still present.

    We now found the root cause for the error Smile

    The Solution(s)

    The Supported Way

    Before changing the SIP Address of a user, remove the user from all Agent Groups he's currently assigned to (as described in KB2393943).
    Then, add the user with his new SIP Address back to the Agent Groups.

    Sounds like great fun if you ever need to change SIP domain and have 50 agents, right?

    The UNsupported Way

    Disclaimer: editing a Lync database table is unsupported. You'll do this at your own risk/responsibility

    Use SQL Management studio to update the user SIP Address in the Agents table. To edit a few rows you can use the "Edit Top 200 Rows" menu item on the table property menu:

    You can then look for the agent record and then change the SIP Address field to the new SIP Address.   I would recommend restarting the RGS Windows Service afterwards.

    Feel free to post any feedback, cheers

    Today I was working on a customer environment where external users had issues retrieving PowerPoint presentations during conferences. 

    The Issue

    When joining a conference with PowerPoint content, users get presented with an empty slide and a slide counter:

    After around 2 minutes this was replaced by the famous error "Either the network connection has been lost or the server is busy. Please check your network connection":

    The Solution

    In this case the Office Web Apps server was published by the still supported but already retired TMG 2010 Reverse Proxy.  The same issue could also occur with a different brand/type of Reverse Proxy in case it applies some filtering techniques on HTTP traffic.

    While capturing logs during a PowerPoint sharing session following Denied message was found "Blocked By HTTP Security Filter: URL Normalization was not complete after one pass"

    This can be solved by changing some HTTP filtering options on the HTTP Publishing rule used for publishing Office Web Apps:

    1. Open the Office Web Apps publishing rule properties
    2. Navigate to the Traffic Tab Page
    3. Click on the Filtering button and select "Configure HTTP"
    4. On the General Tabpage, deactivate "Verify Normalization" and "Block High Bit Characters"
    5. Save the changes

    PowerPoint presentations for external users will now work. Smile

    Without any apparent reason the Lync hybrid deployment with Office 365 (aka Split Domain) stopped working correctly.  The experience fluctuates and can be corrected by restarting the RTC Service on the EDGE Server but that does not last for long.  (usually within the same day the issue returns)  Obviously we want to have a stable environment and don’t want to restart services every day.

    Issue:

    Routing problem to Office 365 from On-Prem EDGE

    ms-diagnostics: 1017;reason="Cannot route From and To domains in this combination";cause="Possible server configuration issue";summary="The domain of the message that corresponds to remote peer (external) is not shared between local and remote deployments";external-domain="domain.com";external-type="domain-type-local";internal-domain="domain.com";internal-type="domain-type-local";source="sip.domain.com"

    Presence cannot be updated and no other communication is possible with the Lync Online user

    image

     

    Temporary solution:

    Restart RTC Service on On-Prem EDGE Server and things work again for a while.

     

    image

     

    The difference is obvious when you look at the SUBSCRIBE messages when it works and when it is broken are very different:

     

    Does not work then this is the SUBSCRIBE message :

    Start-Line: SUBSCRIBE sip:lync.eight@domain.comSIP/2.0

    When it works this is the SUBSCRIBE message :

    Start-Line: SUBSCRIBE sip:sippooldb30e06.infra.lync.com:5061;transport=tls;ms-fe=DB30E06FES04.infra.lync.comSIP/2.0

    Solution:

    Updating the On-Prem EDGE Server to Lync Server 2013 Cumulative Update January 2014 does seem to make it better but only makes the time it works longer but eventually also fails with the same problems.

    Updating both On-Prem EDGE Server and Front-End Pool with Cumulative Update January 2014 seems to fix the Split Domain Setup with Office 365 (at least for what we have been able to test and I will update when there is more news)

    So Update all your Lync Server ASAP to the latest Lync Server 2013 Cumulative Update January 2014.  (no information yet if Lync 2010 updates are required)

    Autodiscover for Exchange Webservices by Lync impacts Exchange Deployments

    The mysterious case of the “Network Password” popup
    http://www.pro-lync.be/blogs/lync2010/archive/2013/10/23/the-mysterious-case-of-the-network-password-popup.aspx

     

    While trying to fix a customers enviroment I have been playing with the following Registry Cache information that you can potentially pre-populate into the Lync clients registry information so that it will find the Exchange Webservices without properly configured Exchange Autodiscover process.  The following screenshot is information that is stored in the registry for the user and acts as a cache for the Exchange Autodiscover information.

    Registry Key For Lync 2010 :
    HKCU\Software\Microsoft\Communicator\<SIP Address>\Autodiscovery

    Registry Key for Lync 2013:
    HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Lync\<<SIP Address>\Autodiscovery

     

    This is an example of Exchange 2010 Cache export from Registry:

    Windows Registry Editor Version 5.00
    [HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Lync\<Replace with real SIP Address>\Autodiscovery]

    "ExternalTimeToLive"=dword:00000018

     

    This is an example of Exchange 2013 Cache export from Registry:

    [HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Lync\johan.delimon@ordina.be\Autodiscovery]
    "cacheVersion"=dword:00000003

    You can use this key to solve autodiscover.domain.com not being provisioned by the Exchange Team and work around the problem manually or by script.  Based on my tests Lync uses this key as a last resort when it cannot find the Exchange Webservices.

    Note: If you make a script that uploads the correct values to the registry you could override a faulty Exchange Autodiscover implementation.  You have to pay attention to the complete registry key because it includes the SIP Address in het key structure so you will need to use a script to generate or lookup the correct SIP Address for every user or this will not work.
