How to access HttpServerUtility.MapPath in a Thread October 9
Usually, when you want the root directory of your website, it is easy to call:
HttpContext.Current.Server.MapPath
or just
Server.MapPath
from a page.
But if you are running your code in a thread or timer, then HttpContext.Current is null (giving you a NullReferenceException), and you are out of luck. 
However, as long as you are not using virtual directories, there is an easy fix:
AppDomain.CurrentDomain.BaseDirectory
will give you the same result, and doesn’t depend on a current HTTP context.

phahar - Try something like this:
‘Declare this as a global variable
shared sMapRootDir as string
‘Execute this in Application_Start
sMapRootDir = Server.MapPath(”.”)
You can then use the variable sMapRootDir throughout your code
