A data communication device that communicates with a storage device via a network includes an input unit for inputting user identification information, a log-in processing unit configured to enable a user to log in to access a storage area of the storage device associated with the user identification information, an accessing unit configured to access the storage area if the user logs in, a determining unit configured to determine whether data processing involving the accessed storage area is ongoing when an instruction is sent to cause the user to log out, and a controller unit configured to enable the user to log out and disable access to the storage area when the data processing is not ongoing, and, when the data processing is ongoing, enable access to the storage area even after the user has logged out until the data processing has been completed.
