i use Windows XP_SP_3 and IIS 5 (local host), build site with asp.net4 and use this code:
Application appClass = new Application();
Document wordDoc = appClass.Documents.Add(Server.MapPath("~") + @"Files\tmp.docx");
wordDoc.SaveAs(@"e:\hp\Files\" + TextBox1.Text + ".docx");
wordDoc.Close();
if run site with VS2010, its OK. but if run with IIS 5 (Local Host), show this error:

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating. If the application is impersonating via , the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.
To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
