A system that is placed in the same workgroup (domain) and the same subnet (network segment) as the PC client uses iSeries™ NetServer™ User Datagram Protocol (UDP) broadcasts.
In many TCP/IP networks, various routers in the network filter out UDP broadcast frames. A client on one side of a router cannot find iSeries NetServer because the UDP broadcast cannot cross the router.
When setting up smaller networks to filter UDP broadcasts, you should consider using other mechanisms for locating the system.
If you place all of your iSeries NetServer and PC clients in the same workgroup and the same subnet, then iSeries NetServer appears in My Network Places of Windows® 2000, Windows XP, Windows Server 2003, and Windows Vista without any additional configuration.
