The copy of a zone that has only the needed resources for finding the authoritative DNS servers in that specific zone (DNS= Domain Name Servers) is called a Stub zone. It also resolves names for DNS namespaces, thing required when names must be resolved from two different DNS namespaces. The Stub zone contains: the master server’s IP that is used for updating the Stub zone and the SOA (Start of Authority), the NS (name server) and the glue A delegated zone records.
Nothing, it’s all maintained automatically.
There is one difference between these two: the forward lookup me name to IP and reverse lookup me IP to name.
Yes and I can explain how. A system administrator is responsible for an entire network which me he/she must take care of multiple things in the same time which is not an easy task. In order to achieve this, an administrator must have high organization skills and a high technical knowledge and he/she must prevent the problems from happening so that he/she won’t have to be forced to fix them.

Hidden or administrative shares are share names with a dollar sign ($) appended to their names. Administrative shares are usually created automatically for the root of each drive letter. They do not display in the network browse list.
Auto Private IP Addressing (APIPA) takes effect on Windows 2000 Professional computers if no DHCP server can be contacted. APIPA assigns the computer an IP address within the range of 169.254.0.0 through 169.254.255.254 with a subnet mask of 255.255.0.0.

DHCP or Dynamic Host Configuration Protocol has the ability to assign an IP automatically, this is done in fact by the server and has a number range. When the system starts an IP is assigned automatically. The DHCP server has port number 68, while the client has 67.
Yes, monitoring is a base activity of a system administrator, he/she manages all the access rights and the server space, security of the user accounts is one of the most important things here. Also an administrator must make sure that the user’s activity doesn’t affect in any way the integrity of the server.
The advantage is that the DHCP server configures all IP’s automatically and the disadvantage is that when you receive a new IP address the machine name remains the same because of its association with the IP. It’s not a real problem but when somebody tries to access the machine by its name it become one.
Switching or trferring roles in an Active Directory can be made with the use of Ntdsutil.exe.

DHCP is used for the DHCP servers, personal computers can get their configuration from a DHCP server on an IP configuration. The server knows nothing about the personal computers until they make a request for information. Usually the most common information sent is IP address and DHCP is used to make a large network administration easier.
Internet Connection Sharing (ICS) uses the DHCP Allocator service to assign dynamic IP addresses to clients on the LAN within the range of 192.168.0.2 through 192.168.0.25@In addition, the DNS Proxy service becomes enabled when you implement ICS.
Staying up-to-date is another strong point of a professional administrator, technology evolves and we must keep up with the flow, otherwise we can’t do our job in a professional way. Market research is the key to an up-to –date work.
This is a responsibility that any system administrator must have assume as a basic skill. Of course there are many types of backup that can be made but all must be known for a successful career.
When you combine NTFS permissions based on users and their group memberships, the least restrictive permissions take precedence. However, explicit Deny entries always override Allow entries.
Make sure it’s either an MSI file, or contains a ZAP file for Group Policy.
