GPLogView

Often times, it is easier to read text files for troubleshooting instead of using the Event Viewer. In fact, exporting event logs into text files may be the only solution when troubleshooting computers in remote locations. GPLogView is a utility you can download and use to export Group Policy event data from the system and operational log into a text, html, or xml file. You can download GPLogView from the Microsoft Download Center (http://go.microsoft.com/fwlink/?LinkId=75004). The following examples show the syntax of commonly used options for GPLogView.

Example 1: Export all Group Policy events

You can use GPLogView to export all Group Policy–related events from the system log and the operational log.

gplogview -o gpevents.txt

Example 2: Export Group Policy events with a specific Activity ID

GPLogView filters Group Policy–related events by Activity ID, which is useful when troubleshooting a specific instance of Group Policy processing.

gplogview -a 8A7C7CE5-F7D0-4d32-8700-57C650A53839 -o gpevents.txt

Example 3: Monitor Mode

You can use GPLogView to capture Group Policy events in real time. GPLogView writes all Group Policy related events to the command window, as they occur. Press CTRL+C to exit monitor mode, or press Q and ENTER.

gplogview -m
