You might want to run the following script to roll over the log files.

Using the windows AT command you could schedule the script to run every day

================================
wscript.echo "Script started ..."

dtNow = Now
sNow = Year(dtNow) & Right("0" & Month(dtNow),2) & Right("0" &
Day(dtNow),2) & "T" & Right("0" & Hour(dtNow),2) & Right("0" &
Minute(dtNow),2) & Right("0" & Second(dtNow),2)

Set traceSettings =
CreateObject("Microsoft.EnterpriseInstrumentation.Configuration.TraceSetting
s")

strTraceConfigFile = traceSettings.GetConfigFileLocation()
traceSettings.load(strTraceConfigFile)

Set colTraceSessions = traceSettings.TraceSessions

For Each traceSession In colTraceSessions

    wscript.echo "Trace Session Name: " & traceSession.Name
    wscript.echo "Trace Session Log Name: " & traceSession.FileName
    wscript.echo "Trace Session Status: " & traceSession.Enabled

    If traceSession.Enabled Then
        path = Left( traceSession.FileName, InStrRev( traceSession.FileName, "\"
) )
        traceSession.FileName = path & traceSession.Name & "_" & sNow & ".log"
        wscript.echo "New Trace Session Log Name: " & traceSession.FileName
    End If

Next

'Since the trace session.config file has been changed we need to save it    
 
If traceSettings.IsDirty Then
    wscript.echo "Saving configuration changes"
    traceSettings.Save
End If

wscript.echo "Script terminated."

--------------------

My application logs messages to windows trace file. It is writing to the
file TraceLog.Log and the trace session settings are default.

Everything is working fine but I would like to write to a new file everyday
instead of writing to the same TraceLog.Log.
Currently it is taking the backup of the file TraceLog.Log but I have no
idea when and how it is taking the backup.

Any one please help

Thanks
