To access a remote server through Named Pipes, you must first have installed and configured communication software for both the client and server workstations. See Software Requirements for the communication protocol requirements for your platform. See Possible Client-to-Server Connectivity Scenarios for the supported communication protocols for your particular client and server.
If you have read and completed the instructions in Setting the DB2COMM Registry Parameter, there are no further steps required to set up Named Pipe communications on the server or to support the Administration Server.
