I have a Centos 6.5 x86_64 kernel 2.6.32-431.5.1 domain server with samba
3.6.9-167 already active. Window 7/XP join to domain regurarly but windows
8 professional fails. Searching in google the problem is "." (dot) in the
domain's name, indeed with the domain name "*domain*" (without* .local*)
windows8 joint to domain. How can i resolve the problem? Have you an idea?


1. In Windows8 I modify registry:

*"DNSNameResolutionRequired"=dword:00000000 *

"*DomainCompatibilityMode"=dword:00000001 *

2. SecPol.msc

*Select Local Policies>Security Options>Network Security: LAN Manager
authorization Level Double click and change to "Send LM & NTLM - use NTLMv2
session security if .....*

        workgroup = domain.local

        delete group script = /usr/sbin/groupdel %g

        add user to group script = /usr/sbin/groupmod -A %u %g
