Lync 2013 Persistent Chat Service not starting

Today I had to installed Persistent Chat to our existing Lync 2013 Standart environement. Plan was use dedicated server for Persistent chat and second dedicated server for SQL Server 2012. Installation was simple as expected. After successfull installation Persistent Chat service could not start. Why? I checked Event Log and found two Events:


Event ID 53553:
The server is not compatible with the database at Data Source=SQL1.HELL.LOCAL;Initial Catalog=mgc;Integrated Security=SSPI


Event ID 53503:
Microsoft Lync Server 2013, Persistent Chat could not start due to the following exception:
 at
Microsoft.Rtc.Internal.Chat.Server.ServerCommon.Exceptions.StopServerException: Unexpected DB version.


Problem was not in SQL server version. SQL server 2012 is supported and installation was successfull. Setup process also created necessary databases.

Solution was install Lync updates using LyncServerUpdateInstaller.exe utility.


Update utility can be downloaded from http://technet.microsoft.com/en-us/lync/dn146015.aspx

After update Persistent chat service can be successfully started.

Copy Group Membership to another user

Hello Guys, I received a request to  copy group membership from one existing user to another one. If you need to create new user, then you can use Copy in Active Directory Users and Computers console. If you want to copy membership to an existing user, you can use PowerShell. To get actual group membership for user John.Doe you can use: get-aduser -identity John.Doe -properties memberof | select-object memberof -expandproperty memberof To copy groups to another existing user use: get-aduser -identity John.Doe -properties memberof | select-object memberof -expandproperty memberof | Add-AdGroupMember -Members Jane.Doe If you wanna know what groups were copied: get-aduser -identity Jane.Doe -properties memberof | select memberof -expandproperty memberof | Add-ADGroupMember -members John.Doe -PassThru You can also copy groupmembership to multiple users: get-aduser -identity Jane.Doe -properties memberof | select memberof -
