When users browse to an ASP.NET Web site, they request that some code run on the server. All processes run within the security context of a specific account. By default, IIS uses the system account. The system account has full access to the IIS server computer but is not allowed to access shared folders on other computers (which are sometimes called NTFS resources). Therefore, you must configure the IIS computer so that it uses an account other than the system account. The IIS Server Configuration section describes several ways to select an alternate account.
