The Question is: I keep seeing the following error message: %%%%%%%%%%% OPCOM 30-NOV-1998 09:09:21.56 %%%%%%%%%%% (from node CHP052 at 30-NOV-1998 09:09:15.06) Message from user DECNET on CHP052 DECnet event 0.7, aborted service request From node 2.52 (CHP052), 30-NOV-1998 09:09:15.01 Circuit MNA-0, Line open error, Unrecognized component, Node My assumption is that it is a device requesting load of it's operating system. How do I find out what this device is? Thanks for your help Robert Stanford, AgrEvo UK LTD The Answer is : There isn't a particularly good way -- the DECnet configurator module (see the DECnet and NCP documentation) can typically be used to determine what sort of Ethernet controller is in use on the device and this can be sometimes useful determining what sort of device is requesting the load, and you can potentially use bridges or bridge adjacency maps to determine which LAN segment the devices is located on. From there, you are often left to search the length of the LAN cable segment for the device. Pending resolution of the device identification process, the Wizard may consider downloading a random file -- a random LOGIN.COM or other file that the device probably won't even be able to process -- into the device merely to get it to "shut up" for a while. Problems such as this can point to a need to keep better track of the addresses of the devices connected to the network and to audit the contents of your LAN segment(s) -- the configurator can potentially be used in conjunction with a database of addresses to detect and report new devices, with new network devices typically directly registered in the database through an administrative process.
