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(82-1)) has been sent 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 (98-1) stored at the registration server and the application server identifier (ID(82-1)) has been designated as the content of the entry of the register (98-1); 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(82-1)) associated with the account identifier (ID(A-1)), the application server identifier (ID(82-1)) associated with the application server ; receiving the application server identifier (ID(82-1)), 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(82-1)) 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(82-1)) has been sent 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 (98-1) stored at the registration server and the application server identifier (ID(82-1)) has been designated as the content of the entry of the register (98-1); 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(82-1)) associated with the account identifier (ID(A-1)), the application server identifier (ID(82-1)) associated with the application server ; receiving the application server identifier (ID(82-1)), 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(82-1)) at the computing device to locate the application server; and accessing the account from the computing device using the account identifier (ID(A-1)). <EOS>
