You've probably figured out the issue, but for general information:
1. DECnet, when configured and the router is rebooted, ALWAYS
starts first and changes ALL MAC adddresses to its algorithmic
prediction.
2. IPX (and XNS for that matter, and Banyan under certain circumstances)
rely on the availability of a MAC address to create the low-order part
of their node addresses.
3. If there was at least one physical LAN interface, that became the
source of the MAC address. Otherwise, you had to configure a MAC
address in the XXX routing command.
If this pseudo-MAC address didn't match the one that DECnet would
have created, either DECnet would break or the non-DECnet protocol
would break.
The situation is even worse when DECnet is adde to the
configuratation after one of the MAC-less workgroup protocols already
is present.

where are you, anyway?
Clearly!
