我的 Active Directory 域控制器出现问题，我的服务器未显示在网络或网上邻居中。我在 Ubuntu Server 14.04.3 上运行 Samba 4.1.6-Ubuntu。
这个问题是电脑从工作组转到域时出现的。如果我输入 smb://ubuntu-server 或 smb://192.168.1.100（服务器的 NetBIOS 名称和 IP 地址），我就能正常访问服务器。
另外，我可以使用“net lookup ubuntu-server”从 NetBIOS 名称获取 IP 地址，使用“nmblookup -A 192.168.1.100”从 IP 地址查找 NetBIOS 名称。
我确实得到了一些命令的结果，可能有一些线索：
andy@ubuntu-server:~$ nmblookup -A 192.168.1.100

WORKGROUP UBUNTU-SERVER
我注意到，当 AD DC 是网络上唯一的域计算机时，它不会成为本地主浏览器。在单台计算机的情况下，我没有通过 nmblookup 找到标题为 FAMILY 的 #1d 条目或 _ _ MSBROWSE _ _ 条目。此外，我发现在上面的 smbclient 命令中，UBUNTU-SERVER 将自己列在工作组 WORKGROUP 下。
运行 testparm 似乎工作正常，但这是我的 /etc/samba/smb.conf 文件：
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.

## Browsing/Identification ###
# Change this to the workgroup/NT-domain name your Samba server will part of
workgroup = FAMILY
; netbios name = ubuntu-server
# server string is the equivalent of the NT Description field

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
# wins support = no
# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
; wins server = w.x.y.z
# This will prevent nmbd to search for NetBIOS names through DNS.

# Andy's entry to make sure that the AD DC becomes the local master
# browser.

#### Networking ####

# interface names are normally preferred
; interfaces = 127.0.0.0/8 eth0
# Only bind to the named interfaces and/or networks; you must use the

# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself. However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
; bind interfaces only = yes
#### Debugging/Accounting ####
# This tells Samba to use a separate log file for each machine
# that connects
log file = /var/log/samba/log.%m
# Cap the size of the individual log files (in KiB).
max log size = 1000
# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
# syslog only = no
# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.

# Do something sensible when Samba crashes: mail the admin a backtrace
panic action = /usr/share/samba/panic-action %d
####### Authentication #######
# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary
# domain controller", "classic backup domain controller", "active
# directory domain controller".
#
# Most people will want "standalone sever" or "member server".
# Running as "active directory domain controller" will require first
# running "samba-tool domain provision" to wipe databases and create a
# new domain.

# If you are using encrypted passwords, Samba will need to know what

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
unix password sync = yes
# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<[email protected]> for
# sending the correct chat script for the passwd program in Debian Sarge).
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections

我想知道如何让我的域控制器再次出现在网络文件夹中。
如果需要任何其他系统信息或测试结果，请告诉我。
