Description

On several servers after installing the hotfix XA650R07W2K8R2X64017 the IMA service won't start anymore although no error was returned during Hotfix installation.
In the IMA Runtime registry, the Currently Loading Plugin will have MfSrvss.dll.

Moreover, when checking the Certificate settings for the hotfix, error is seen under General tab as "Digital Signature Information One of the Counter Signatures is not valid. The file may have been altered."

Resolution

Check if the server is having Internet Access.
If there is no Internet access, the issue may happen and we need to ensure the Root Certificate is updated on the server.

Problem Cause

Machine specific Root Certificates not updated on the server.
