No mix; all is 100.

No DECnet, only one interface per machine.

Maybe I can find time to swap the SCSI card, which seems a bit flaky.  
(All traffic---LAT, TCPIP, SCS, HBVS) is on the same network.)  I had to 
replace one bootserver recently.  I believe that the problem appeared 
only after that.  There are errors on its SCSI bus, and this is the 
machine which occasionally refuses connections.
