EO/EE 5.7: MachineKeys Folder keeps growing in size

Problem Statement

After installing Equitrac Office / Express 5.7 the folder C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys keeps growing in size.


This issue can be caused by the Equitrac DCS service not having the required components installed. This will cause DCS service to continuously restart, causing the C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys to grow in size.


On the Windows server, in the Add roles and services wizard, install the 4.5 feature from the .NET Framework 4.5 section, for Windows Server 2012 R2.  For newer OS versions, the .NET Framework version will be newer.

Care must be taken when removing the old machine keys to free up space.  Contact Technical Support if assistance is required.
