Try "eventcreate.exe"

An example:

eventcreate /ID 1 /L APPLICATION /T INFORMATION  /SO MYEVENTSOURCE /D "My first log"

This will create a new event source named MYEVENTSOURCE under APPLICATION event log as INFORMATION event type.

I think this utility is included only from XP onwards.

Try PowerShell 2.0's EventLog cmdlets

Throwing this in for PowerShell 2.0 and upwards:

• Run New-EventLog once to register the event source:

  New-EventLog -LogName Application -Source MyApp

• Then use Write-EventLog to write to the log:

  Write-EventLog     -LogName Application     -Source MyApp     -EntryType Error     -Message "Immunity to iocaine powder not detected, dying now"     -EventId 1

You can also use Windows PowerShell with the following command:

if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) {    [System.Diagnostics.EventLog]::CreateEventSource($source, "Application")}

Make sure to check that the source does not exist before calling CreateEventSource, otherwise it will throw an exception.
