To turn WMI error logging on or off
Open WMI Control
In the console tree, right-click WMI Control, and then click Properties.
Click the Logging tab.
Under Logging level, click Disabled to turn logging off. Click either Errors only or Verbose to turn logging on.
You must be an administrator or a member of the Administrators group on the computer you are managing, or have been given appropriate permissions, to perform this task.
To open the WMI Control console, click Start, click Run, type wmimgmt.msc, and then click OK.
Errors only reports errors that occur within WMI. Verbose reports all actions and errors.
Verbose logging can negatively impact system performance, so select Verbose only when you need more extensive information about the events leading to errors.
Log files are maintained for the WMI core and framework, as well as for each WMI-enabled provider.
You can set the maximum size for log files under Maximum size. When a log file has reached the maximum size, it is renamed with the .lo_ extension, and a new log file is created with the .log extension. When that file reaches the defined maximum size, the first file is deleted and the process is repeated.
You can set logging levels on a remote computer or a local computer To access a remote computer, right-click WMI Control, click Connect to another computer, click Another computer, and then type the name of the computer to which you want to connect. If you are using WMI Control from the Computer Management console, right-click the Computer Management node to connect to the other computer.
You can connect to the computer as a different user if you have multiple logon names. To connect as another user, click the General tab, click Change, clear the Log on as current user check box, and then type a user name and password.
It is recommended that you include log files when reporting issues associated with WMI services.
