In order to enhance debugging of wininet.dll for application developers, Microsoft has added ETW tracing support for this component. The feature will be available beginning with Windows Vista Beta 2 builds.
To use the feature, wininet.dll users should open a command prompt window with elevated privileges:
1. Click the Start button, point to All Programs, and then click Accessories.
2. Right-click Command Prompt, and then click Run Elevated or Run as administrator (depending on what Vista build you are running).
Initialize WinINet tracing:
This command will initialize the ETW framework for WinINet tracing, using wininettrace.etl as the output file for trace data.
Run IE or an application that exercises the WinINet APIs
logman stop “wininettrace” -ets
Create a human readable (xml) log file:
tracerpt “wininettrace.etl” –y –o “wininetracelog.xml” –of xml
This command will generate an XML log file called wininetracelog.xml that contains the WinINet events logged.
