This problem occurs because an information disclosure vulnerability exists in the Transport Layer Security protocol and the Secure Sockets Layer protocol (TLS/SSL) as they are implemented in the encryption component of the Microsoft .NET Framework. An attacker who successfully exploits this vulnerability can decrypt encrypted TLS/SSL traffic.

Here is the resolutions...

While deploying Lync Server 2013 Archiving and Monitoring role, I ran into the below error message.




























Check your SQL Server which will be used for Archiving and Monitoring for Lync Server 2013. I found that databases were not created.
























Resolution:
Login to your SQL Server and open SQL Server Management Studio and connect to the SQL Server. Create LcsCDR and QoEMetrics database manually.



































Rerun the deployment again and it will complete successfully.

While publishing the Topology. I got the error "Error: Cannot open Service Control Manager on computer "servername.domain.com". This operation might require other privileges."

















I checked the connectivity, server could ping each other with IP and NetBIOS name. Checked the firewall setting on both SQL and FE server.
Disabled the Firewall  on SQL server and tried Publishing the Topology and it completed successfully.

Environment Topology:
1 DC/GC and DNS running on Windows Server 2008 R2 with SP1
1 Lync Server 2013 installed on Windows Server 2012
1 Exchange Server 2010 SP3 with RU2
1 Client Windows 8 x64.
1 Office 2013 Lync Client and Office 2013 Basic Lync Client.
1 Certificate Authority and ADFS 2.0 Server
1 Forefront TMG Server 2010 SP2

I am not able to login to Lync 2013 client after the fresh installation of Lync Server 2013 with CU2. I am getting the error standard error message "The user name, password, or domain appears to be incorrect."

































Tried with different accounts as well, but still getting the same error message. I found an update for Lync 2013 client and installed it.















After the update, tried Login, still the same error message. Now I enable the logging on the client so that it will generate the event in case of failure. I found the Event ID 3, 1 and 12.









































































Now as per the event, there's something wrong with the installation or the files of Lync Client 2013 which got installed. I installed the full version of Office 2013 Lync Client, now I tried with Lync Basic client and it failed with the same error message.

































I decided to check the issue with Lync 2010 Client and installed the client after uninstalling the Lync 2013 client from the workstation.
Now I tried to login to the Test account and it worked, no more error with Lync 2010 client.





































Resolution/Workaround: Install Lync 2010 client.
I am not sure, why is it failing to login with Lync 2013 client, I am still looking into the issue and will update the post once I find the solution.

The paper describes how to configure a test lab consisting of servers running Exchange Server 2013, Lync Server 2013, and SharePoint Server 2013 by using five server computers and two client computers. After verifying that all three types of servers are working, you then configure server-to-server trust relationships between them. The resulting test lab can be used as a basis for scenarios and solutions that use a combination of Exchange Server 2013, Lync Server 2013, and SharePoint Server 2013, and Microsoft Office 2013.

The following is a list of top three KEMP LoadMaster options and things to be aware of when configuring these options on the LoadMaster appliance (virtual or hardware) in a network infrastructure. In particular, the options that will be discussed in detail are: Transparency, High Availability, and Bonding. The goal of this document is to educate an end user with the best approach for when configuring these options as to avoid any possible first time setup/deployment issues with the LoadMaster.

1. Transparency
2. High Availability
3. Bonding/VLAN’s

I came across with this error "Command execution failed: Error Constructing or Publishing Certificate" when requesting certificate from internal CA server for Lync server 2013 running on windows server 2012.


After digging into the issue and the error I found that I will have to restart the Active Directory Certificate Services on CA server. Looked into application log and found the event id 53.


























I checked and found that Active Directory Certificate Services service on CA server service is already running.
































Now I just had to restart Active Directory Certificate Services service. After restarting the service, request the certificates again from Lync server and it will complete successfully.
