Windows 7 can see but not access OS X share

You likely are just running into an issue with changes MS made in Vista's networking that still exist today. Try the following from Post #8 in the thread below. The bottom of the post was updated for there being no Local Security Policy in the Home version of Windows.

Sorry, but this has nothing to do with Vista or Win 7. This has to do with the fact that Apple dumped SMB due to licensing issues and uses a home baked SMB client that does not work well and is buggy. Like the fact that it does not show mounted SMB shares anymore in the left side of finder. The WINS bug is just one of many. If you have a domain controller, join the macs and the pc to the same domain sometimes helps. Sometimes you need to turn off file sharing and then fix the wins and then turn your file sharing back on. I have contacted Apple many times about this...you should as well.

 

No, OS X server has the same problems. Samba changed to the GPLv3 license and apple did not accept the license, so they made their own SMB implementation.

The easiest way to fix this is to setup an old computer as a WINS server for your local network and the OS X box can pull those wins values from the server on boot.

 

unfortunately no, you have to remember that apple had to write their smb code from scratch starting with lion. Maybe it's based on an old samba version though, not really sure.

perhaps you could put together a script to add the workgroup name at boot up?

 

Mavericks and the new OS X Server should solve your problems hopefully. SMB2.

 

Which is a big reason i am looking forward to mavericks! Maybe we will get some other nifty things as well. We can only hope.

 

See your OS X from Windows 7

on Your mac computer, Go to System Preferences, check File Sharing, on New Window check "share files and folders using SMB"
On Windows file sharing bottom filed you must see your user name, press done

Go to windows pc, go to network, give user name and password !!!!

 

Plus going from a 10.9.x or better OS X system and are trying to connect to Windows 7 or better using the string cifs:// instead of the smb://. This forces SMB2 to use the SMB1 connection instead. Windows 7 or better connects better with this command.

 

Try direct IP address

We have two servers running using OS X Server, occasionally and under duress I connect with a Windows machine. One server operates as normal, the other (identical settings, even with lots of tweaks) I have the issue where the Windows machine can "see" the server but never prompts for the login information and gives me "Windows cannot access" I solved this by typing the IP address of the computer I am trying to access instead of using the host name. You can see the IP address when viewing the File Sharing panel in System Preferences.

 

Hi,

run regedit.exe as administrator on the Win 7 machine.

Delete this DWORD line in the Win 7 registry and you shall be fine:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LmCompatibilityLevel

You do not need to restart the Win 7 system in order that you can now successfully connect for example to the: \\MACPRO\HARDDRIVESHARE from Win 7 machine.

You only need to fill the administrator name and password login for the Mac OSX computer and you shall now successfully map the Mac network drive on the Win 7 machine.

Best regards,

Hi,

The registry variable:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\control\LSA\LMCompatibilityLevel

is used to set the minimum challenge/response algorithm.

The DWORD value can be: 0, 1, 2, 3, 4, 5.

Please know that the Mountain Lion OSX, Mavericks OSX and Yosemite OSX domian controllers does not accept LM, NTLM, LMv2, and NTLMv2 responses so if the Win 7 and Win 8.1 sends the LM, NTLM, LMv2, and NTLMv2 responses to MAC with these OSes it does not get responses back so the connection is unsuccessfull from the Win 7 or Win 8.1 side so the problem is in the Win 7 or Win 8.1 operating system which does not allow the connection to be made!

If you need this DWORD line in the registry you can stil connect from the MAC environment to the Win 7
or Win 8.1 shares!
But you can not connect from Win 7 or Win 8.1 environment to MAC OSX shares!

Best regards,

Gorazd.

Gorazd,

I have WIN7 Ultimate; is it safe to delete LmCompatibilityLevel as well?

Also, I have disabled smb2/3 in WIN7; can that now be safely enabled?

Finally, are you mapping the Mac shared drive to a drive letter bypassing the NETBIOS name?

 

Awesome!

This worked for me, thanks so much. I was worried that my problem was that my Windows laptop is on a domain rather than a workgroup, and hence my I wouldn't be able to assign the same workgroup in WINS on my Mac. But I tried this and voila, I can map my shared folders onto my Win7 laptop.

 

Windows 7 File Sharing

@Gorazd Thank you ever so much. Your solution was spot on.

 

Just change settings on OSX

Just an update for future people that find this thread: You do NOT need to go changing registry keys in Windows to get this to work.

Do what SStamatis has mentioned, which is simply to change file sharing settings on OSX (Yosemite in my case) to use SMB _and_ individually select which OSX accounts should be accessible by the windows machine.

Here are SStamatis instructions again (edited for clarity):

"on Your mac computer, Go to System Preferences, enable File Sharing, click on the Options button, enable "share files and folders using SMB" and then enable (via the checkbox) each OSX account in the "Windows file sharing" section"
