Configuring Log4N using a shared dllhost.exe.config doesnt work

Each serviced component must have its own configuration file i.e Application.config and Application.manifest

Initialize Log4N using XmlConfigurator.Configure() in a static constructor

Set the ApplicationRoot to the directory that contains Application.config and Application.manifest files

How to set Application Root

Select Administrative Tools->Component Services

Expand Console Root->Component Services->Computers->My Computer->COM+ Applications
