My application writes to the application event log. The app has access rights (followed the regedit solution here http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B329291&FR=1')and an entry does get written.

I use the following VB code to add an entry -

    Public Shared Sub LogError(ByVal err As SoapException)
        Dim Log As New EventLog
        Log.Source = ConfigConstants.SERVICENAME
        Log.WriteEntry(err.Message, EventLogEntryType.Error)
    End Sub

When I view the entry I get -

"The description for Event ID(0) is Source (MQSWebService) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer..."

The registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Eventlog\Application\MQSWebService exists but having scanned the ASP.NET key it has an EventMessageFile (that was a guess) value but duplicating that makes no difference.

Does anyone have any idea what might be causing this?

Many thanks,

Steve.
