XP and SAMBA

[Christopher Travers]

I sent something about this earlier but the info was wrong.

It seems that the recent builds of XP have changed the authentication 
protocol to v2 of NTLM.  The default setting of Windows XP prevents thenm 
from loggin into to NT4 PDCs as well as Samba servers, though this can be 
manually set:

The registry key is:

HKLM\System\CurrentControlSet\Control\Lsa\LmCompatibilityLevel

With the following possible values:

0 = Send LM & NTLM responses
1 = Send LM & NTLM - use NTLMv2 session security if negotiated
2 = Send NTLM response only
3 = Send NTLMv2 response only
4 = Send NTLMv2 response only\refuse LM
5 = Send NTLMv2 response only\refuse LM & NTLM

We might want to look at registry patches initially to reduce the value to 2 
(the default is 3).

Thought you might find it interesting.
