A remote administration system's ability to communicate with remote computers using in-band communications is contingent on many factors (e.g., the operability of the network over which the in-band communications is carried and, to some extent, the correct operation of the software on the remote computer). Accordingly, there may come a time (e.g., during a network outage) where the remote administration system can no longer communicate with the remote computer over the preferred communications protocol (e.g., using in-band communications). In such a case, a status detector of the remote administration system may detect that an error has occurred (e.g., by "pinging" the remote computer and getting no response or by losing an open network connection) and then switch to a less preferred communications protocol (e.g., using out-of-band communications). A remote administration system's ability to communicate (figure 1) with remote computers using m-band communications is contingent on many factors (e g, the operability of the network over which the m-band communications is carried and, to some extent, the correct operation of the software on the remote computer) Accordingly, there may come a time (e g, during a network outage) where the remote administration system can no longer communicate with the remote computer over the referred communications protocol (.beta. g using m-band communications) In such a case, a status detector of the remote administration system may detect that an error (figure 5) has occurred (e g, by "pinging" the remote computer and getting no response or by losing an open network connection) and then switch to a less preferred communications protocol (e g, using out-of-band communications)
La capacité d'un système de gestion à distance de communiquer avec des ordinateurs éloignés à l'aide de communications intrabandes dépend de plusieurs facteurs (par exemple, l'exploitabilité du réseau sur lequel s'effectuent les communications intrabandes, et dans une certaine mesure, l'exploitation correcte du logiciel sur l'ordinateur éloigné). Par conséquent, il peut arriver (par exemple, lors d'une défaillance du réseau) que le système de gestion à distance ne puisse plus communiquer avec l'ordinateur éloigné par le protocole de communications préféré (par exemple, à l'aide de communications intrabandes). Dans un tel cas, un détecteur d'état du système de gestion à distance peut détecter l'apparition d'une erreur (par exemple, lorsqu'il n'obtient aucune réaction lors de la vérification de la présence de l'ordinateur éloigné ou lorsqu'il perd une connexion de réseau ouverte), puis le détecteur peut commuter sur un protocole de communications de second choix (faisant par exemple intervenir des communications extrabandes).
