We're having a problem connecting a MicroVAX 2000 to a MicroVAX II over Ethernet. If you try to establish a logical DECnet link between one and the other, the connection is not established and times out eventually (60 seconds in our case) with the message "remote node is not currently reachable". The network looks like this: +------+ +-------+ +-------+ +-------------+ | 2000 |---| DEMPR |--| DELNI |---| MicroVAX II | +------+ +-------+ +---+---+ +-------------+ | H4000 H4000 |---------------------------|------------------|---------------| | +-------+ | DELNI | +---+---+ | +-----+-----+ | DECserver | +-----------+ When DECnet starts on the 2000, the MicroVAX II sees it, because if the 2000 changes its address, that change is reflected in the MicroVAX II's database. We don't suspect the hardware because the DECserver can reach both the 2000 and the MicroVAX II with no problems. Has anyone ever seen this before? Does anyone have any guesses?

If either of your node numbers are greater than 255, make sure that the MAXIMUM ADDRESS parameter is set appropriately in each DECnet database. Here's how to set it: $ RUN SYS$SYSTEM:NCP NCP> DEFINE EXECUTOR MAXIMUM ADDRESS 1023 (or at least as high as your highest node number) NCP> SET EXECUTOR MAXIMUM ADDRESS 1023 NCP> EXIT You might also want to make sure both nodes are in the same DECnet area; I seem to remember that inter-area communications require an area router, even if the nodes are on the same Ethernet. I'm not sure of that, though; if you have a full doc set, check the VMS Networking Manual (mine's not nearby right now). Hope this helps! Ed Thierbach Roy F. Weston, Inc.
