Q: Some Windows 7 computers cannot log in to Yosemite Server regardless of user

I just upgraded our office server from Mavericks to Yosemite hoping it would resolve some of the ongoing funkyness I and others have been experiencing with the SMBX server component for Windows file shares.

 

The upgrade went remarkably smoothly for the most part, with most Mac and Windows clients not even noticing the difference.

 

However, two of my Windows 7 clients are unable to connect to the server--they get a password failure message regardless of what account they try to log into (including my own admin account), and regardless of what account the local Windows machine is logged in to.  Trying to connect to the server, or map a drive on it, simply fails as if the user credentials were rejected.  They are, however, able to bring it up the web interface via HTTP, and print through it via CUPS, so it's not a DNS or routing issue. They also bring up the login dialogue correctly, indicating that they're talking to it, it's just that the login fails even with known-good credentials.

 

I've tried rebooting the Windows clients multiple times, clearing everything out of Credential Manager in Windows, making sure there are no phantom connections listed in Connected Users on the server, even deleting and re-adding users on the server.  The only thing I haven't tried is rebooting the server because I can't kick the other 20 users off during the day for the sake of a couple.

 

All the Windows clients, both working and not, should be configured the same. The only thing I can think of that might be different with the two that are misbehaving is that they may have been left on during the update while the rest were shut down, but it seems like a reboot should have cleared out any stuck connections from this.

 

Any suggestions?  What the heck is going on here?  Random errors I'm used to, but not rejecting al logins as if it had a bad password, and only from certain systems.

    Thanks Marc, this definitely cleared our issues. Prior to Yosemite, the LmCompatibility Level needed to be set to 1 for Win PCs to be able to see 10.7-10.9 servers. Setting to 3 might be the result of adding the encryption option to SMB3. Thanks for the help though, it's been driving us nuts over here.

    Thanks a million! I remember changing this value for an earlier version. Very surprised that this was the answer again.

    Does anyone know of a solution to this that does not involved editing registry settings in Windows?  I have Server 4.0x installed in a large corporate environment and we have several PCs that need to connect however all the PCs are corporate imaged and cannot be toyed with. I managed to get a few connected via the FTP service but it's far from ideal and convoluted to explain to a user who is used to mapping drives.

     

    I have tried enabling smb:ntlm auth = "yes" and smb:lanman auth = “yes" on the server.

     

    But it makes no difference....

    Thank you Marc

    I had exactly the same problem. 2 win7 pc's 1 ok and the other could not log in.

    In my case the registry key had the value 0. Changing it to 3 solved the problem.

    Thanks a lot it works great now!!

    Following this helped me however it was lmcompatibilitylevel that I changed. Didn't seem clear based on this post. This is on Windows 7

    Thanks for the help.  I've messing with this since OS X came out.  Such and easy fix for very hard find.

    I was having this issue connecting some Windows 10 machines to a server running 10.6.8. I added the key in for Windows 10, but value of 3 wasn't working. I went and played around and for some reason the value of 2 worked for me.

    Thanks Marc, after beating my head against the wall for 2 hours changing it to 3 did it. I even ran across a Windows user tip to change it to 1!

    Thanks! I couldn't figure it out. I could connect to the Yosemite Mac with other Macs and Window XP machines. I could even connect to virtualbox instances running within the Mac. I never would have figured it out on my own.

    I have this exact same problem on El Capitan. However, the registry workaround is not working for me. The login credentials window keep coming back and I am unable to login.

    Yes! Your answer finally got my Windows machine to show shared files on my OS X machine! I have only ever seen this work once in my lifetime and I can't believe the answer lies in some obscure registry setting that I don't believe a single OS X or Windows developer even knows about, probably.

     

    Now if I could only find out why it shares my entire hard drive instead of the public folder that I selected...
