Hi there !
I faced this error when I tried to communicate with an Agilent 34410a DMM by TCP/IP over my corporate LAN. I downloaded an instrument driver for that specific DMM and added the appropriate passport inside MAX.
I got the error when I began to create new a VISA TCP/IP resource in devices and interfaces in MAX. Please note that the instrument is reachable using a hyperterminal session and correctly respond to any directive I send to it.
Has anybody a suggestion for me?
Thanks in advance,

Rolly Grisenti
