Hello techagent,
A limited amount of tracing is possible, but the trace data is difficult to interpret; judging by the limited amount of discussion of this topic that I could find on the Web, almost no-one tries this.
The command "netsh ras show tracing" (or, possibly, "netsh nps show tracing") shows trace sources that can be enabled for textual logging to \Windows\tracing (with the command "netsh ras set tracing"), but often no trace data is written unless WPP tracing is also enabled (the trace mask and level set on the WPP tracing also affects the textual tracing).
The textual log data looks like this:
If you are prepared to share the trace data, then I would be happy to help with its analysis.
