[2008 R2] Permission denied

hi all, hope in your help.

I've in my machine with windows server 2008 R2 this folder c:\inetpub\wwwroot\applicationWWW.

For this folder applicationWWW in server web IIS 7 setup I've the Windows Authentication enabled and all other Authentication's type disabled.

I tried this code page ASP in the browser of server 2008 R2 http://localhost/applicationWWW/default.asp , but I've this error:

<%response.expires=0
response.buffer=true%><%
Set Wrd = CreateObject("Word.Application")
Set ExcelApp = CreateObject("Excel.Application")
%>

Microsoft VBScript runtime error '800a0046' Permission denied

If I try the same asp code/page http://myserverweb/applicationWWW/default.asp in browser of different machine (windows 7 or windows XP) on server I don't have error, why?
Can you help me?

thank you in advance.
