If the page is meant to be accessed anonymously, give the IUSR_<machinename> account full control to the ASP page, and the folder and files where the database is located. Additionally, if the path to the database is being referenced using UNC (\\Server\Share), ensure that the Share Permissions allow the IUSR_<machinename> account full access. This step applies even if the share is on the local Web server.
If the page has been secured such that the IUSR_<machinename> can't access the file or database, then ensure that the user's account that is being authenticated has full control to the appropriate folders and files.
At a minimum, the account being used needs Create, Destroy, Read, Write to work with the .ldb file. Specific permission can be applied to the database to limit access
什么是IUSR_<machinename>，UNC (\\Server\Share），how to ensure the user's acount is being authenticated has full control to the appropriate folders and files???
