samba - Nov 2014 - Windows 8.1 client not able to see and connect to samba server

Hi,
I am using a samba server for file sharing in our companies IPv4 based
LAN. The samba server is running as VM on a ubuntu 14.04 qemu/kvm host
using ubuntu 14.04 as OS.

I am using the lastet version available for samba:
4.1.6+dfsg-1ubuntu2.14.04.3

My Windows 7 and Windows 8.1 client are able to find the server and
connect to the shares but the Windows 8.1 client of a colleague is not
able to find and connect to the server.

The failing client is able to ping the IP of the samba server but when
connecting to it, I get the following error message:

0x80004005 unspecified error

Searching for this error results in some hits that requires to change
three registry entries under

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManWorkstation\Parameters]
DWORD DomainCompatibilityMode 1
DWORD DNSNameResolutionRequired 0
DWORD RequireSecureNegotiate 0

All three do not solve the problem.

Any ideas where to look next?

Kind regards,
Eike

Is the time on the machine set properly? Have you joined the domain with
the new machine or not?

If your other Win 8.1 client didn't require these changes, it can't be
the cause on the other one. ;-)

Registry changes are only required, if this is an NT4 domain - not an
AD. And it's only required for joining the NT4 domain:
https://wiki.samba.org/index.php/Registry_changes_for_NT4-style_domains




But it's not that easy to help. You didn't gave much information about
your environment.
* Is this a Member/PDC/DC/Standalone?
* DNS resolution on the client works?
* Errors in the logs?
* etc.
