SQL Server Replication Services are used by SQL Server to replicate and synchronize database objects, either in entirety or a subset of the objects present, across replication agents, which might be other database servers across the network, or database caches on the client side. Replication follows a publisher/subscriber model, i.e., the changes are sent out by one database server ("publisher") and are received by others ("subscribers").

replmerg.exe executes as a process under the SYSTEM account with extensive privileges (the system and the administrator accounts have the same file privileges). It is installed with a couple of know programs including Microsoft SQL Server Native Client published by Microsoft Corporation, Microsoft SQL Server Native Client from Microsoft Corporation and Microsoft SQL Server Native Client by Microsoft Corporation. The assembly utilizes the .NET run-time framework (which is required to be installed on the PC). The file is digitally signed by Microsoft Corporation. and is compiled as a 32 bit program.
