Dear Jeremy,

Thanks for your quick response.
   I understand that 3.0.14a doesn't have the ntlmv2 support and the
code is very old too.

My concern is what is the fix given in the latest version to make
smbclient operation to work with vista when 
"Client use spnego = Yes" & "client ntlmv2 auth =yes" in smb.conf file.

I had seen in the release note that Mr.Andrew had given a fix for ntlmv2
support for vista in 3.0.21a,b,c.

"Support raw NTLMSSP authentication for Windows Vista clients". Could
you please tell me the exact code changes done for this ntlmv2 support,
which will be very much helpful for us.

Thanks & Regards

3.0.14a is very old and out of maintanence as far as new features
is concerned. Please upgrade to the latest version of Samba which
fully supports Windows Vista.
