Fundamentals -- you may be onto something. Though TCP/IP initialization completes without error, running "ipconfig /all" yields "No DHCP data available." I get the same result from two identical cards, both configured the same way.
I do note that both cards are old non-PNP ISA cards, which I thought would be appropriate for this vintage rig. In the meantime, in the Registry I changed HKLM\SYSTEM\CurrentControlSet\Control\Lsa\LMCompatibilityLevel=3 –> 0, which is "Send LM & NTLM responses" per https://technet.microsoft.com/en-us/library/jj852207%28v=ws.10%29.aspx. Then I rebooted. But I still get the same error on the DOS client. @ Roberto Fazzalari: I have been avoiding your approach to date since I never had more than a rank novice's acquaintance with Wireshark. But it may be that I'll have to get reacquainted!
