Thanks for the response SuperDave,
Security_Essentials is the name that I chose when I created the Custom view for Microsoft Security Essentials.
You can see it in the screen shot of the execution of Event Viewer under Custom Views - upper left. I added the undersore so that I didn't need double quotes in the command execution. It work fine when executed from the Event Viewer Custom View.
Patio, thank you also,
I don't understand your response of msseces.exe.
If you look at the help for C:\>eventvwr /?
it does define the required inputs for the command. The msseces.exe isn't mentioned.
