There are three places I'd check: 1) The actual network Interface on the Unix system (should be able to verify with ifconfig) Had it bind to eth0 instead of vmbr0, the error went away and it can see an adjacent node. 2) The address configured in klt20.ini (assuming you're using the Panda distribution) That is now configured correctly. Seems this problem can easily be solved by just bringing up another VM, I have the RAM and DISK. ;) 3) The DECnet address specified in 7-1-CONFIG.CMD --Marc
