You define a network node server list for an end node (EN) with a VBUILD definition statement followed by one or more NETSRVR definition statements.
If you choose not to define a network node server list, a default network node server list consisting of a single nameless NETSRVR definition statement is automatically activated when the end node is initialized.
If the NNSPREF start option is defined, the network node specified will have a higher priority then any other network node specified in the active NETSRVR list.
