I have use asp.net create a web page (index.aspx) and write a function that use faxcom to send a fax out when user click a button. But there's an fax exception : access is denied. So I've changed the aspnet account from users group to adminstrators group and that solve the problem. It seems to be the access problem between aspnet and fax component. I want to allow the aspnet account to use fax com only and not as adminstrator because of security problem. So which access should I change to allow aspnet account can use the webserver's faxcom to send fax out?
