Share Mac Files (Yosemite) with Windows I have a combination of Win7 - XP &amp; Apple macbook machines, running on my windows network.

The macbook up and till recently had Mavericks 10.9.5 OS X ,, a few days ago I upgraded the macbook to OS X Yosemite.

With upgrades you do get the odd thing going wrong but I have managed t resolve all but one problem in that I can no longer see any of the macbook-shared folders within the XP network icon.

I can see them and login to them via the Win 7 machines network icon, but I can not see any of the mac folders ( or drive ) within XP …

I therefore have to do the following :-

Start - Run

Then type the path to the macbook folder .. a login prompt and password appears but when I put in the user and password ,, the login re-appears but first with my XP machine user name back slash and the macbook user with password .. reappearing again and again after trying to login.
The error was logon failure: unknown username or password

I can though WinSCP from my XP to the macbook using the same login credentials

But I just can not get past this XP to macbook network access – I can however login from the macbook to the XP machines network drives and folders.

Does anybody have any solutions to this as I have come up stuck here
I had a similar issue and this post solved it for me:

It may be the same discussion that Tetsujin references, but the setting to use is NOT "Send LM &amp; NTLM - use NTLMv2 session security if negotiated" -- you should use "Send NTLMv2 response only". After I made that change, I connected to the share, put in my Mac username &amp; pwd, and it connected.
