I am running Mercury mail on my windows PC.
Occasionally it will stop running.
I need a script that I can schedule to run every 30 minutes that will:

1.  check the running processes for mercury.exe
2.  If mercury.exe is in the running processes, do nothing and go back to sleep
3.  If mercury.exe is not found in the running prcesses, restart mercury.exe (i.e. c:\mercury\mercury.exe)
4.  Rerun step 2
4.  Output actions to a log file

Any suggestions?

You can do something like...

Dim WshShell, oExec
Set WshShell = CreateObject("WScript.Shell")

' launch it...
Set oExec = WshShell.Exec("calc")

Dim targetTime
targetTime = DateAdd("n", 30, Now) ' 30 minutes from now

While True
    ' check every 5 seconds to see if our targetTime has been passed
    While targetTime > Now
        WScript.Sleep 5000 ' (max is 32,767 --> approx 30 seconds)
    Wend

    ' if it's closed...run it again
    If oExec.Status <> 0 Then
        Set oExec = WshShell.Exec("calc")
    End If

    ' set next "event" for 30 minutes out...
    targetTime = DateAdd("n", 30, Now) ' 30 minutes from now
Wend

Something like...

Const ForReading = 1, ForWriting = 2, ForAppending = 8

Dim fileName, fso, f, lines

fileName = "c:\someLog.txt"
Set fso = CreateObject("Scripting.FileSystemObject")

Dim WshShell, oExec
Set WshShell = CreateObject("WScript.Shell")

' launch it...
Set f = fso.OpenTextFile(fileName, ForAppending, True)
Set oExec = WshShell.Exec("calc")
f.Write(Now & " Application Started" & vbCrLf)  
f.Close

Dim targetTime
targetTime = DateAdd("n", 30, Now) ' 30 minutes from now

While True
    ' check every 5 seconds to see if our targetTime has been passed
    While targetTime > Now
        WScript.Sleep 5000 ' (max is 32,767 --> approx 30 seconds)
    Wend

    ' if it's closed...run it again
    Set f = fso.OpenTextFile(fileName, ForAppending, True)
    If oExec.Status <> 0 Then
        Set oExec = WshShell.Exec("calc")
        f.Write(Now & " Application Restarted" & vbCrLf)  
    Else
        f.Write(Now & " Application Still Alive" & vbCrLf)  
    End If
    f.Close

    ' set next "event" for 30 minutes out...
    targetTime = DateAdd("n", 30, Now) ' 30 minutes from now
Wend

How do I set the path to the executable?

Here is the code I am using that i get a path error on:
Const ForReading = 1, ForWriting = 2, ForAppending = 8

Dim fileName, fso, f, lines

fileName = "c:\Log.txt"
Set fso = CreateObject("Scripting.FileSystemObject")

Dim WshShell, oExec
Set WshShell = CreateObject("WScript.Shell")

' launch it...
Set f = fso.OpenTextFile(fileName, ForAppending, True)
Set oExec = WshShell.Exec("c:\mercury\mercury.exe")
f.Write(Now & " Application Started" & vbCrLf)  
f.Close

Dim targetTime
targetTime = DateAdd("n", 30, Now) ' 30 minutes from now

While True
    ' check every 5 seconds to see if our targetTime has been passed
    While targetTime > Now
        WScript.Sleep 5000 ' (max is 32,767 --> approx 30 seconds)
    Wend

    ' if it's closed...run it again
    Set f = fso.OpenTextFile(fileName, ForAppending, True)
    If oExec.Status <> 0 Then
        Set oExec = WshShell.Exec("c:\mercury\mercury.exe")
        f.Write(Now & " Application Restarted" & vbCrLf)  
    Else
        f.Write(Now & " Application Still Alive" & vbCrLf)  
    End If
    f.Close

    ' set next "event" for 30 minutes out...
    targetTime = DateAdd("n", 30, Now) ' 30 minutes from now
Wend
