[EDN Admin]

Good Morning to all <img title="Smilie" src="http://images.daniweb.com/smilies/sleek/qqb014.gif" border="0" alt=" <br/>
<br/>
Currently im developing a Windows Service in order to automatically send me e-mails with my remote computer operating status.<br/>
I already checked MSDN documentation about this subject http://msdn.microsoft.com/en-us/library/ycy63t34.aspx" target="_blank
http://msdn.microsoft.com/en-us/library/ycy63t34.aspx and changed the code to use on my situation. But... i dont receive e-mails from it when the remote computer is normally turned off.<br/>
<br/>
Someone could help me with this issue?<br/>
<br/>
