Tracing

Tracing records the sequence of programming functions called during a process to a file. To record detailed information about IGMP routing protocol processes in the log file SystemRoot\tracing\IGMPv2.log, set the value of the EnableFileTracing registry entry (HKEY_LOCAL_MACHINE\Software\Microsoft\tracing\IGMPV2) to 1. After you are done viewing the traced information, set EnableFileTracing back to its original setting of 0.

The tracing information can be complex and very detailed. This information is predominantly useful only to Microsoft support professionals, or to network administrators who are very experienced with the Windows 2000 Routing and Remote Access service. The tracing information can be saved as files and sent to Microsoft support for analysis. For more information about the tracing facility, see "Routing and Remote Access Service" in this book.
