sp_changereplicationserverpasswords (Transact-SQL)
Changes stored passwords for the Microsoft Windows account or Microsoft SQL Server login used by replication agents when connecting to servers in a replication topology. You would normally have to change a password for each individual agent running at a server, even if they all use the same login or account. This stored procedure enables you to change the password for all instances of a given SQL Server Login or Windows account used by all replication agents that run at a server. This stored procedure is executed at any server in the replication topology on the master database.
