Early versions of MS14-066 in Microsoft’s KB 2992611 alter the encryption algorithms used by Transport Layer Security (TLS), forcing the server that hosts TMCM 6.0 to use an encryption algorithm not supported by SMEX 10.2. This occurs when negotiating the encryption algorithm for the TLS session. For this reason, TLS stops working on several platforms.

KB 2992611 has undergone a number of revisions. And if you downloaded the update before December 9, 2014, you will probably encounter the issue.

To solve the error when trying to access SMEX 10.2 on the server where the earlier version of Microsoft KB 2992611 has been applied:

1. Go to Control Panel and click the following:

   For Windows 2008: Programs > Programs and Features

   For Windows 2012: Program and Features

2. In the left-hand menu, select View installed updates.
3. Find Update for Microsoft Windows (KB2992611) from the list of updates, right-click on it and select Uninstall.
4.  Restart the system.

   For Windows 2008: Click Start > Select the Restart option.

   For Windows 2012: Go to the bottom right corner of the desktop and select Settings > Power > Restart.

5. Go to the Microsoft Download Center and locate the most recent Microsoft MS14-066 update version, which is version 3.0.
6. Click the operating system (OS) version you are using on the server where TMCM is installed and then choose Download.
7. Go to Downloads, locate the WindowsX.X-KB2992611-vX-xXX.msu file, right-click on it and select Install to apply the update you have just downloaded.  
8. Restart the server and you should be able to access SMEX 10.2.
