I have a version 3.0.23b Samba server and a version 3.0.25c Samba
>From a Windows 2003 Server I can map drives to the 23b server but not to
the 25c one.
The two samba servers are setup the same (apart from server name etc).
I think this is a problem to do with NTLMv2. 
When "LAN Manager authentication level" is set to "Send NTLMv2 response
only" I can connect to the 23b server but not the 25c one. 
When I change this setting to "Send LM & NTLM - use NTLMv2 session
security if negotiated" I can connect to both servers.
What has changed between 23b and 25c to cause this and how do I get 25c
to work again without leaving the setting at "Send LM & NTLM"?
