Confirm the User Name and Password are correct
If you send documents to a shared folder with access control, you must enter the user name and password. If the user name and password set for the file server address are not correct, you cannot send the document. For the user account, contact your network administrator.
The setting procedure of the shared folders with access control differs depending on the OS. For how to set the shared folder with access control, see "Shared Folder with Access Control" in the content in the Related information for your OS.
