Take the script code that uses the WshShell.Exec method and put it in an
external *.vbs script in a folder on the server where the ASP code can
execute it under cscript.exe using the WshShell.Run method with the wait
option.
Since the code is now running under cscript, the wscript.sleep method is
available.
Your only other choice is a 3rd party component (or one you write yourself)
the provides the equivalent of WScript.Sleep to ASP code.
