To Find the Computer Name

To find the name of the computer with N-Linx Server, open the Control Panel and choose System. The Computer name field lists the name.

To Change the Port

N-Linx Agent by default uses port 5672 to communicate with N-Linx Server. If this port is in use, type the new port after a colon in the N-Linx Server Address field.
