“We can’t get more message right now” Error in Lync 2013 chat room

July 28, 2015 2 comments

You are laughing to see the subject line I have used in this post “We can’t get more message right now”. Yes this is one of the error message been reported by one of my Lync 2013 persistent chat user.

He is active member of many chat room and use it very often. Other members of chat room can use the room without any issue. I did lots of research over web and also thought to open case with Microsoft but doing it before i tried something funny.

The error message got by user is below.


I added user as additional manager in the room as below.


User exit lync clients and tried to post message back the chat rooms, all’s started working fine. I am still not sure what is the root cause of this behavior and trying to get it from MS :).

Unable to create CMS database for the Lync FE pool Error “Install-CsDatabase : Command execution failed: The requested object does not exist. “

We were in transition phase to move CMS database from lync 2010 to Lync 2013 server. All users were migrated and now migrating CMS.

Lync 2010 Environment:

Lync 2010 Front End Pool contain two front end servers and one of the front end server is CMS master Server. This pool has one standalone SQL server which is holding CMS database along with other database.

Lync 2013 Environment:

Lync 2013 have three front end servers. This front end pool have two node cluster SQL which is holding backend datasbe for this pool. Backend SQL cluster is also holding instance for one other front end pool called “BIG Meeting”.

 Problem :
As per MS article we issues the below command to create the new Central Management store database in the Lync Server 2013 SQL Server database which is a prereqsuite to start the CMS realocation

Install-CsDatabase -CentralManagementDatabase -SqlServerFqdn “FQDN SQLInstance” -SqlInstanceName “SQLInstance”

Above command failed with below error

Install-CsDatabase : Command execution failed: The requested object does not exist. (Exception from HRESULT: 0x80010114)”

Solution: As we have SQL cluster hosting all lync 2013 BE instance, we must use database and log file path to tell the cmdlets to create CMS database.

Then we used a command as below with ‘DatabasePaths’ switch.

Install-CsDatabase -CentralManagementDatabase -SqlServerFqdn “FQDN SQLInstance” -SqlInstanceName “SQLInstance” -DatabasePaths “E:\CSLog”,”F:\CSLog”,”G:\CSDB”

This command was able to successfully created the xds database.

We also move the CMS from Lync 2010 to Lync server 2013 pool, it was completed successfully.

Hope it will help others hosting Lync 2010/2013 database in SQL cluster form 🙂 !!!

Importance of High Port Range (50,000 – 59,999) between two Edge Pool

December 10, 2014 4 comments

We were working on building of second lync 2013 Edge Pool to achieve HA and Load balancing for our Lync infrastructure and came across with lots of funny and nice things. I cannot highlight all funny things here,But going to explain the most funniest part.

In our environment, we have two edge pool, one pool is for lync 2010 frond end pool media association and new edge pool is for lync 2013 media association. Environment has few mediation pool which is connected with lync 2010 edge server for media association.

If someone call from remote access to desk phone (connected Via Mediation server) using lync 2013 edge server it was getting failed. When we saw the lync traces and netstat logs it was showing that, lync 2013 edge servers and remote client is trying to reach 50k port ranges of Lync 2010 edge server (This is enterprise voice calls and going to use lync 2010 mediation which is associated with lync 2010 edge servers)

So we must have to open 50K port ranges for both of edge pool servers so client can connect and do the enterprise voice calling seamlessly. Below is the technet forum discussion which also helped us to understand more and taking decision to open this high port ranges


Hope, it will help someone else J

How to track account locked out in TMG 2010 SP2

November 15, 2014 Leave a comment

Started noticing that few AD accounts are getting locked out within Active Directory where the source, as per the monitoring reports shows that the TMG Servers of your environment, which is working as a reverse proxy for mobile clients.

An account lockout occurs after several failed authentication attempts that are made by incoming web proxy or web publishing requests (for example, an ActiveSync device that has a user’s old password saved).

To track it , go into Log & Reportss in TMG Array and find out failed authentication attempts information below.

  • Run Forefront TMG 2010 console
  • Select Logs & Reports item on the left pane
  • Select Logging tab on the center pane
  • Select Tasks tab on the right pane
  • Select Edit Filter under Logging task

The TMG logs cannot be used to identify the source of the request hence still you are not able to find any denied connection and device detail which may casing the account locking problem.


By default, the change in behavior is not enabled, and the following script should be run to enable the new behavior. After you enable the new behavior, TMG will log the username that is associated with a failed logon attempt in the Username field as follows, instead of being logged as Anonymous:

domain\username (!)

Go thro with the below KB article to enable script for search failed login.



Now you can see the below logs report which shows the several denied connection.


You can also see more information about device expanding “Additional Information” section into one of the log

Disable Video modalitese for certian CSusers in Lync 2013

September 24, 2014 Leave a comment

I have a requirement to disable video for few lync users sitting in remote site dealing with low bandwidth. This whole exercise is to provide good user experience for Audio

To do this, we need to follow below steps

  1. Create a Conferencing policy using below cmdlet


2. Disable Video by set Boolean value $false for EnableP2PVideo


I have disabled sharing too, hence you can change other parameter on base of your requirement

See this article for more details about parameter and CS conferencing policy


3. See below CS conferencing policy which shows the EnableP2PVideo & EnableAppDesktopSharing


Now you can assign this policy for individual users or group of users thru CSV file

Use below cmdlet to assign for single user

Get-CsUser Useralias | Grant-CsConferencingPolicy -PolicyName Policyname

Use below cmdlet for a list thru CSV file (Change location accordingly)

import-csv C:\input.CSV | ForEach-Object {

write-host “Login” $_.login

Get-CsUser $_.login | Grant-CsConferencingPolicy -PolicyName DisableVideoANDSharing }

Hope it will help someone dealing with same need 🙂 !!!

Failed to save Web Ticket Signing certificate to the file store

Issue : Lync mobile client can not sign-in .

During my troubleshooting on my lync director server, I see Event 4101 which indicating “Certificate file path” can not be  found. I tried to browse the File store asscitae with DIR servers and can not browse. So its confirm that problem is occurring due to store only. You can also see this event if you have permission problem on lync store directory.


Worked with Storage admin to enable the lyncShare directory with old data which resolved the issue.
