I have had to rebuild my Windows 7 PC and all has gone fairly well until I tried to connect to a Samba share on a legacy Linux box running Redhat 8.
No matter what combination of domain / user /password I would just see the same message of:
"The specified network password is not correct."
This is a misleading error, very annoying and a little confusing until I found a hint that Windows 7 default authentication was not supported on older Samba implementations.
I guess I figured this out once before as it used to work before the rebuild! Anyway here is the solution:
1. Control Panel->System and Security->Administrative Tools->Local Security Policy (or run secpol.msc).
2. Select Local Policies->Security Options->Network security: LAN Manager authentication level.
3. Select 'Send LM and NTLM - use NTLMv2 session security if negotiated' and click OK.
