To allow NTLMv1 or LM challenge-response operations, first become a user
with Administrator rights. Next, run the program secpol.msc. Under Local
Policies then Security Options, there should be something that reads,
"Network Security: LAN Manager authentication level." By default, "Send
NTLMv2 response only" is selected. There are a few options available, but
choosing "Send LM & NTLM - use NTLMv2 session security if negotiated" seems
to make the most sense. Everything should now magically start to work if
using non-NTLMv2 aware systems.
