We have a similar configuration with a DEC5400 as a server. We
experienced a similar problem on one DEC3100. Turned out that
we forgot to completely reconfigure the rc.local file. One of the
peculiarities was forgetting to comment out the mop_mon entry.
A bunch of VAXstation3100's kept trying to load their brains from
the DEC3100. More importantly, we found that the NFS and local
daemon entries, or something like that were out of order. All
I can remember for sure was that the default rc.local file
required extensive reworking to get the 3100 to work gracefully.
