Resolution:

The problem is caused by a missing Active Servers' registry entry.

There are a couple of work arounds:

1. Any server can be started with the 'Allow Performance Monitoring' box checked under the general tab of a servers properties. When this server starts up, it will detect that there is no 'Active Servers' entry in the registry and create it. Once this registry entry has been created, the messages should no longer appear.
2. If you have no intention of using performance counters for enterprise server then the following registry key can be removed:
   HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Micro Focus Server
   This will prevent cas0perf.dll from being called by perfmon (or any other consumer)
3. If you do not intend to use Enterprise Server at all, then you can simply uninstall it from Programs and Features or Add or Remove Programs where you need to:
   a. select Micro Focus Net Express 5.1
   b. click on Change
   c. click on Enterprise Server to mark the feature with a X, i.e "This feature will not be available"
   d. click OK to uninstall Enterprise Server and its related components
