FWM 01003 null When Logging Into Central Management Console

When logging into the SAP Central Management Console used for managing security in UMS, I received the following error:

Server not found or server may be down (FWM 01003) null

Thanks to this post, it turns out that the CMS.exe process was not running. I could tell by looking in Task Manager. To start the process:

1. Run Central Configuration Manager
2. (Re)start Server Intelligence Agent
