How do you open ssl0.9.7a dav2 server at downloadregistrysmartcom port 80?
This is something that needs to be fixed / changed on the site's server, not your computer. There is nothing wrong with your computer; there is something wrong with the site you are visiting.

How many types of Domain controller?
The domain controller is only of one type but it can have different roles
Domain Naming master
RID master
PDC
Schema Master
Infrastructure master
Schema master (forest wide):
The Schema Master controls all updates to the Schema within the forest.
Domain Naming Master (forest wide):
The Domain Naming Master role is responsible for the creation and deletion of domains in the forest.
PDC Emulator (domain wide):
The PDC emulator role provides backwards compatability for Windows NT backup domain controllers (BDCs), the PDC emulator advertises itself as the primary domain controller for the domain. It also acts as the domain master browser and maintains the latest password for all users within the domain.
Infrastructure Master (domain wide):
The Infrastructure Manager role is responsible for updating references from objects within its domain with objects in other domains.
RID Master (domain wide):
The RID Master manages the Security Identifier (SID) for every object within the
Can a user defined in active directory access a shared drive if that user is not part of the domain?
No a user defined in active directory cannot access a shared drive if they are not part of the domain. You will need to set them up as a user on your computer.
Active Directory replication uses compressed and encrypted traffic to reduce the impact on corporate WAN links. This helps in minimizing bandwidth usage and ensuring efficient communication between domain controllers.
What database serves as a central repository for all Active Directory objects?
The global catalog server.
What are requirement to install ad on a new server?
· An NTFS partition with enough free space (250MB minimum)
· An Administrator's username and password
· The correct operating system version
· A NIC
· Properly configured TCP/IP (IP address, subnet mask and - optional - default gateway)
· A network connection (to a hub or to another computer via a crossover cable)
· An operational DNS server (which can be installed on the DC itself)
· A Domain name that you want to use
· The Windows 2000 or Windows Server 2003 CD media (or at least the i386 folder)

What type of a domain group is most like the local group on a member server?
This the answer straight from the book:
Domain local groups in a Windows Server 2003 mixed or interim domain are limited
to the domain controller on which they reside. This is very similar to the way local
groups on a member server are limited to the computers on which they reside.
Unless the domain functional level is raised to Windows 2000 native or Windows
Server 2003, the domain local groups cannot be used for permission assignment
on any servers in the domain other than the domain controllers.
Are the SRV records of a child domain updated automatically during Active Directory installation?
After running DCPROMO, A text file containing the appropriate DNS resource records for the domain controller is created. The file called Netlogon.dns is created in the %systemroot%\System32\config folder and contains all the records needed to register the resource records of the domain controller.
Netlogon.dns is used by the Windows 2000 NetLogon service and to support Active Directory for non-Windows 2000 DNS servers.
If you are using a DNS server that supports the SRV resource record but does not support dynamic updates (such as a UNIX-based DNS server or a Windows NT Server 4.0 DNS server), you can import the records in Netlogon.dns into the appropriate primary zone file to manually configure the primary zone on that server to support Active Directory.
so if you are using w2k with dynamic update it will automatically create the SRV
Where the global catalog available?
The global catalog contains a complete replica of all objects in Active Directory for its Host domain, and contains a partial replica of all objects in Active Directory for every other domain in the forest. The global catalog is a distributed data repository that contains a searchable, partial representation of every object in every domain in a multidomain Active Directory forest. The global catalog is stored on domain controllers that have been designated as global catalog servers and is distributed through multimaster replication. Searches that are directed to the global catalog are faster because they do not involve referrals to different domain controllers. In addition to configuration and schema directory partition replicas, every domain controller in a Windows 2000 Server or Windows Server 2003 forest stores a full, writable replica of a single domain directory partition. Therefore, a domain controller can locate only the objects in its domain. Locating an object in a different domain would require the user or application to provide the domain of the requested object. The global catalog provides the ability to locate objects from any domain without having to know the domain name. A global catalog server is a domain controller that, in addition to its full, writable domain directory partition replica, also stores a partial, read-only replica of all other domain directory partitions in the forest. The additional domain directory partitions are partial because only a limited set of attributes is included for each object. By including only the attributes that are most used for searching, every object in every domain in even the largest forest can be represented in the database of a single global catalog server.
What happens if primary domain controller fails?
You wont be able to access the network resources/login properly to your account.
Relativist Fallacy
What naming context is replicated across the domain?
Schema naming context and configuration naming context is replicated across domain in the forest
The client/server model is a computing model that acts as distributed application which partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients.[1] Often clients and servers communicate over acomputer network on separate hardware, but both client and server may reside in the same system. A server machine is a host that is running one or more server programs which share their resources with clients. A client does not share any of its resources, but requests a server's content or service function. Clients therefore initiate communication sessions with servers which await incoming requests.
Schematic clients-server interaction.
The client/server characteristic describes the relationship of cooperating programs in an application. The server component provides a function or service to one or many clients, which initiate requests for such services. A notable example of this is the way OpenGLtreats the video card of a computer as a server, with the actual application making rendering requests to it. This model is further solidified with the OpenGL Shading Language, with the user writing small programs that live in video memory, and are requested from the main program through the graphics driver.
Functions such as email exchange, web access and database access are built on the client/server model. Users accessing banking services from their computer use a web browser client to send a request to a web server at a bank. That program may in turn forward the request to its own database client program, which sends a request to a database server at another bank computer to retrieve the account information. The balance is returned to the bank database client, which in turn serves it back to the web browser client, displaying the results to the user. The client-server model has become one of the central ideas ofnetwork computing. Many business applications being written today use the client-server model, as do the Internet's main application protocols, such as HTTP, SMTP, Telnet, and DNS.
The interaction between client and server is often described using sequence diagrams. The Unified Modeling Language has support for sequence diagrams.
Specific types of clients include web browsers, email clients, and online chat clients.
Specific types of servers include web servers, ftp servers, application servers, database servers, name servers, mail servers, file servers,print servers, and terminal servers. Most web services are also types of servers.
What type of groups would you use when configuring distribution groups in a multiple domain forest?
Use Universal distribution groups in a multiple-domain environment. The membership of universal distribution groups is replicated to each global catalog server in each domain
What is whitespace in active directory?
During ordinary operation, the white space in the Active Directory database file becomes fragmented. Each time garbage collection runs (every 12 hours, by default), white space is automatically defragmented online to optimize its use within the database file. The unused disk space is thereby maintained for the database; it is not returned to the file system.
