First Claim
1. A method for a client computer to find a network address of a password server computer having a public key, the method comprising:
- performing, in parallel, primary and backup search procedures for a network address of the password server computer, wherein the backup search procedure comprises broadcasting a search query on a network, the search query configured to cause password server computers available on the network to send corresponding responses to the client computer;
using a network address of the password server computer acquired by the backup search procedure when the address of the password server computer cannot be identified using the primary search procedure; and
establishing a connection with the password server computer using the network address found,wherein;
the public key is an identifier of the password server computer,the public key identifies a plurality of password server computers having different network addresses, andthe backup search procedure searches for the password server computer with the search query that is based at least in part on the public key.

Abstract
A method for a client computer to find a network address of a server computer by searching for the network address using at a backup search procedure if the address of the server computer cannot be identified using a primary search procedure. The primary and backup search procedures can be performed in parallel and multiple backup search procedures can be performed to identify the address of the server computer. Alternatively, the primary and backup search procedures can be performed in serial wherein the backup search procedure is performed only when the primary search procedure does not identify the address of the server computer.
