One thing to look into is the security level Windows 7 is using. On the Windows 7 machine:

  1. Go to Administrative Tools.
  2. Go to Local Security Policy.
  3. Double click Local Policies.
  4. Double click Security Options.
  5. Find Network security: LAN Manager authentication level.

By default Windows 7 is set to Send NTLMv2 response only. This is Microsoft attempting to make Windows 7 more secure; however, it has the added effect of blocking requests from older operating systems that do not understand NTLMv2. I had a similar problem mapping a drive in Windows 7 to a file share on an AS400. I would receive the pop-up for my user name and password. Enter both correctly, then be prompted for credentials again. It would never go through.

Change the policy to Send LM & NTLM – use NTLMv2 session security if negotiated. It will use NTLMv2 if it can but use a less secure authentication level if needed.

just want to make a note here that the smb protocol actually checks for the date of the authentication request. i had a similar problem and it turned out to be that i had accidentally changed the date on my windows pc in the bios and so it would not accept my credentials no matter what. setting the date correctly fixed it for me.

that’s kind of a special case, but i figure worth mentioning as an easy thing to overlook.

Did you try to put WORKGROUPusername in the username field ?

It will be helpful if you can see samba logs on windows machine.
