samba - Dec 2013 - HELP: smb 3.6.20 and 3.6.21 broken with Win 8.1

We have a total of 2 desktops upgraded to the recent Window 8.1.
Neither is able to map the home share,  which happens to be a DFS root, and of
course cannot access DFS links.

Errors we are seeing are
                "Server unable to perform requested operation"
Or
                Using net use - system error 64
Or
                Using net use  with ip addr in lieu of NetBIOS name - system
error 58

Nothing has changed on the samba host.  All other desktops work just fine.
Attached is our smb.conf.  The home share referred to above is:  SPH_Shares.
The host is RedHat Linux 5.10 kernel 2.6.18-371.1.2.el5
# smbd -V
Version 3.6.20
We have tried 3.6.21 on another server with same result.

Thanking all in advance for any suggestions.

Can you try 4.0 or 4.1?
The 3.6 series is meanwhile out of maintainance and in 
security-fixes-only mode. So if it's a bug, there's not a big chance to 
get this fixed. But 4.0 and 4.1 bring very much new changes and 
improvements and maybe the problem is already gone/fixed.

As 4 is the next release after 3, it isn't a big thing to upgrade (it's 
like switching from 3.5.x to 3.6.x).

In my test environment I have a 4.1.0 server (but without DFS) and 8.1 
and this runs fine. And in production DFS with 4.1.0, but with Win7, 
what also works good.

But if the problem is around DFS/Win8.1 and still exists in 4.1, then 
you can open a bug report, add your smb.conf and a level 10 debug 
logfile containing the try to access the share.
