The Remote Access Service Diagnostics Tool (Rasdiag.exe) collects diagnostic information about remote services and places that information in a file. Administrators can use this tool to work with Microsoft Product Support Services to troubleshoot remote connection issues by taking a snapshot of the configuration data and capturing an attempted remote connection.
This tool is not documented in the Help file for Support Tools (Suptools.chm).
