A method for configuring a computing device for interaction with an application server comprising: receiving an account identifier (ID(A-1)) at the computing device, the account identifier (ID(A-1)) associated with an account (A-1) on the application server, wherein the application server is an application server of a plurality of application servers, wherein the account (A-1) has been created on the application server and the account identifier (ID(A-1)) and an application server identifier (ID) has been sent (315, 320) to and stored at a registration server, wherein at the registration server the account identifier (ID(A-1)) has been designated as a key for an entry of a register stored at the registration server and the application server identifier (ID) has been designated as the content of the entry of the register; retrieving a preconfigured registration server address identifying a first registration server from a memory of the computing device; sending the account identifier (ID(A-1)) to the first registration server, the first registration server configured to determine the application server identifier (ID) associated with the account identifier (ID(A-1)), the application server identifier (ID) associated with the application server; receiving the application server identifier (ID), at the computing device, from the first registration server; establishing communication between the computing device and the application server using the application server identifier (ID) at the computing device to locate the application server; and accessing the account from the computing device using the account identifier (ID(A-1)). receiving an account identifier (ID(A-1)) at the computing device, the account identifier (ID(A-1)) associated with an account (A-1) on the application server, wherein the application server is an application server of a plurality of application servers, wherein the account (A-1) has been created on the application server and the account identifier (ID(A-1)) and an application server identifier (ID) has been sent (315, 320) to and stored at a registration server, wherein at the registration server the account identifier (ID(A-1)) has been designated as a key for an entry of a register stored at the registration server and the application server identifier (ID) has been designated as the content of the entry of the register; retrieving a preconfigured registration server address identifying a first registration server from a memory of the computing device; sending the account identifier (ID(A-1)) to the first registration server, the first registration server configured to determine the application server identifier (ID) associated with the account identifier (ID(A-1)), the application server identifier (ID) associated with the application server; receiving the application server identifier (ID), at the computing device, from the first registration server; establishing communication between the computing device and the application server using the application server identifier (ID) at the computing device to locate the application server; and accessing the account from the computing device using the account identifier (ID(A-1)).
