The name and location of the message log are specified in the configuration file for the IHE Service (Hyland.Integrations.IHE.NTService.exe.config). The default name is Messages.svclog, and its default location is the location of the IHE Service executable.
The log opens using the WCF Service Trace Viewer Tool (SvcTraceViewer.exe). If this tool is not available on the current system, it can be obtained through an installation of the Windows Software Development Kit (SDK). The Windows SDK is available for download from the Windows Dev Center site.
Detailed information about the WCF Service Trace Viewer Tool can be found on the Microsoft Developer Network (MSDN) site.
