If you use another connection type such as Remote Access Service (RAS) to connect to the file server, the logon credentials used are different from the credentials that you used to create the network mapping. When you try to access the network drive to restore the connection, the operating system tries to use the logon credentials of the RAS connection. If the file share server does not accept the logon credentials of the RAS connection, the operating system cannot access the share. Then, the operation system tries to re-create the mapping to the already-used network drive, and the error occurs.
