What is LDP?
A:
The Lightweight Directory Access Protocol, or LDAP is an
application protocol for querying and modifying directory
services running over TCP/IP.[1]
A directory is a set of objects with attributes organized in
a logical and hierarchical manner. The most common example
is the telephone directory, which consists of a series of
names (either of persons or organizations) organized
alphabetically, with each name having an address and phone
number attached.
An LDAP directory tree often reflects various political,
geographic, and/or organizational boundaries, depending on
the model chosen. LDAP deployments today tend to use Domain
name system (DNS) names for structuring the topmost levels
of the hierarchy. Deeper inside the directory might appear
entries representing people, organizational units, printers,
documents, groups of people or anything else that represents
a given tree entry (or multiple entries).
Its current version is LDAPv3, which is specified in a
series of Internet Engineering Task Force (IETF) Standard
Track Requests for comments (RFCs) as detailed in RFC 4510.
LDAP means Light-Weight Directory Access Protocol. It
determines how an object in an Active directory should be
named. LDAP (Lightweight Directory Access Protocol) is a
proposed open standard for accessing global or local
directory services over a network and/or the Internet. A
directory, in this sense, is very much like a phone book.
LDAP can handle other information, but at present it is
typically used to associate names with phone numbers and
email addresses. LDAP directories are designed to support a
high volume of queries, but the data stored in the directory
does not change very often. It works on port no. 389. LDAP
is sometimes known as X.500 Lite. X.500 is an international
standard for directories and full-featured, but it is also
complex, requiring a lot of computing resources and the full
OSI stack. LDAP, in contrast, can run easily on a PC and
over TCP/IP. LDAP can access X.500 directories but does not
support every capability of X.500
What is REPLMON?
A: Replmon is the first tool you should use when
troubleshooting Active Directory replication issues. As it
is a graphical tool, replication issues are easy to see and
somewhat easier to diagnose than using its command line
counterparts. The purpose of this document is to guide you
in how to use it, list some common replication errors and
show some examples of when replication issues can stop other
network installation actions.

What is ADSIEDIT?

A: ADSIEdit is a Microsoft Management Console (MMC) snap-in
that acts as a low-level editor for Active Directory. It is
a Graphical User Interface (GUI) tool. Network
administrators can use it for common administrative tasks
such as adding, deleting, and moving objects with a
directory service. The attributes for each object can be
edited or deleted by using this tool. ADSIEdit uses the ADSI
application programming interfaces (APIs) to access Active
Directory. The following are the required files for using
this tool:
· ADSIEDIT.DLL
· ADSIEDIT.MSC
Regarding system requirements, a connection to an Active
Directory environment and Microsoft Management Console (MMC)
is necessary
What is NETDOM?
A: NETDOM is a command-line tool that allows management of
Windows domains and trust relationships. It is used for
batch management of trusts, joining computers to domains,
verifying trusts, and secure channels
A:
Enables administrators to manage Active Directory domains
and trust relationships from the command prompt.
Netdom is a command-line tool that is built into Windows
Server 2008. It is available if you have the Active
Directory Domain Services (AD DS) server role installed. To
use netdom, you must run the netdom command from an elevated
command prompt. To open an elevated command prompt, click
Start, right-click Command Prompt, and then click Run as
administrator.
You can use netdom to:

Join a computer that runs Windows XP Professional or Windows
Vista to a Windows Server 2008 or Windows Server 2003 or
Windows 2000 or Windows NT 4.0 domain.
Provide an option to specify the organizational unit (OU)
for the computer account.
Generate a random computer password for an initial Join
operation.
Manage computer accounts for domain member workstations and
member servers. Management operations include:
Add, Remove, Query.
An option to specify the OU for the computer account.
An option to move an existing computer account for a member
workstation from one domain to another while maintaining the
security descriptor on the computer account.
Establish one-way or two-way trust relationships between
domains, including the following kinds of trust relationships:
From a Windows 2000 or Windows Server 2003 or Windows Server
2008 domain to a Windows NT 4.0 domain.
From a Windows 2000 or Windows Server 2003 or Windows Server
2008 domain to a Windows 2000 or Windows Server 2003 or
Windows Server 2008 domain in another enterprise.
Between two Windows 2000 or Windows Server 2003 or Windows
Server 2008 domains in an enterprise (a shortcut trust).
The Windows Server 2008 or Windows Server 2003 or Windows
2000 Server half of an interoperable Kerberos protocol realm.
Verify or reset the secure channel for the following
configurations:
Member workstations and servers.
Backup domain controllers (BDCs) in a Windows NT 4.0 domain.
Specific Windows Server 2008 or Windows Server 2003 or
Windows 2000 replicas.
Manage trust relationships between domains, including the
following operations:
Enumerate trust relationships (direct and indirect).
View and change some attributes on a trust.

Syntax
Netdom uses the following general syntaxes:

NetDom <Operation> [<Computer>] [{/d: | /domain:} <Domain>]
[<Options>]
NetDom help <Operation
