Increase 20% of broadband connection

Increase 20% of broadband connection (Essential
Microsoft reserve 20% of your available bandwidth for their own purposes
(suspect for updates and interrogating your machine etc..)

Here's how to get it back:

Click Start-->Run-->type "gpedit.msc" without the ""

This opens the group policy editor. Then go to:

Local Computer Policy-->Computer Configuration-->Administrative Templates-->Network-->QOS Packet Scheduler-->Limit Reservable Bandwidth

Double click on Limit Reservable bandwidth. It will say it is not configured, but the truth is under the 'Explain' tab :

"By default, the Packet Scheduler limits the system to 20 percent of the bandwidth of a connection, but you can use this setting to override the default."

So the trick is to ENABLE reservable bandwidth, then set it to ZERO. This will allow the system to reserve nothing, rather than the default 20%.
Works on XP Pro and 2000

Difference Between DDR1 DDR2 RAMs


















DDR2 is very similar to DDR1 RAM.


DDR2 is a 240-pin module, DDR1  is a 184-pin module.
DDR RAM size is 15cm, DDR1 will have notch at the centre of the length i.e., 7.5 cm and DDR2 7cm

Random-Access-Memory(RAM)

Random Access Memory (RAM)

Random Access Memory (RAM) provides space for your computer to read and write data to be accessed by the CPU (central processing unit). When people refer to a computer's memory, they usually mean its RAM.

If you add more RAM to your computer, you reduce the number of times your CPU must read data from your hard disk. This usually allows your computer to work considerably faster, as RAM is many times faster than a hard disk.

RAM is volatile, so data stored in RAM stays there only as long as your computer is running. As soon as you turn the computer off, the data stored in RAM disappears.


DRAM -- Dynamic RAM

Dynamic random access memory (DRAM) is the most common kind of random access memory (RAM) for personal computers and workstations. Memory is the network of electrically-charged points in which a computer stores quickly accessible data in the form of 0s and 1s. Random access means that the PC processor can access any part of the memory or data storage space directly rather than having to proceed sequentially from some starting place. DRAM is dynamic in that, unlike static RAM (SRAM), it needs to have its storage cells refreshed or given a new electronic charge every few milliseconds. Static RAM does not need refreshing because it operates on the principle of moving current that is switched in one of two directions rather than a storage cell that holds a charge in place. Static RAM is generally used for cache memory, which can be accessed more quickly than DRAM.
DRAM stores each bit in a storage cell consisting of a capacitor and a transistor. Capacitors tend to lose their charge rather quickly; thus, the need for recharging. A variety of other RAM interfaces to the computer exist, such as EDO RAM and SDRAM.

RDRAM -- Rambus DRAM



If you are using RDRAM, make sure that all memory sockets of a channel are filled with either a memory chip or a continuity module.
RDRAM often has to be installed in pairs of the same type of memory chips.

RDRAM devices may be configured into single-, dual- or quad-channel RIMM modules. For dual-channel or quad-channel (4-channel) RDRAM chipsets and motherboards, memory module upgrades should be in matched pairs. For instance, to add 512 MByte of memory into a dual or 4-channel system, two matched 256 MByte modules should be inserted.

32-bit RIMM modules, such as RIMM 4200, 4800, and 6400 modules, can be upgraded singly on dual channel systems.


DIMM (Dual Inline Memory Module) or RIMM (Rambus Inline Memory Module)?


A: RIMM is the trademarked name for a Direct Rambus memory module.
RDRAM is available only in RIMM packages (such as 184-pin RIMMs).
RIMMs look similar to DIMMs, but have a different pin count. (Typically DIMMs are 168-pin, while RIMMs are 184-pin.) RIMMs transfer data in 16-bit chunks.


Example of RDRAM speeds include PC 800 (PC-800 or PC800) and PC 1066 (PC-1006 or PC1066).

Dual Channel RDRAM -- Dual-channel PC800 RDRAM, as found in Intel's 850 Pentium 4 chipset, provides a higher bandwidth than even PC2700 DDR-SDRAM (DDR333).




SDRAM -- Synchronous DRAM (JEDEC SDRAM)



SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time. The speed of SDRAM is rated in MHz rather than in nanoseconds (ns). This makes it easier to compare the bus speed and the RAM chip speed. You can convert the RAM clock speed to nanoseconds by dividing the chip speed into 1 billion ns (which is one second). For example, an 83 MHz RAM would be equivalent to 12 ns.


DDR (Double Data Rate SDRAM)


DDR basically doubles the rate of data transfer of standard SDRAM by transferring data on the up and down tick of a clock cycle. DDR memory operating at 333MHz actually operates at 166MHz * 2 (aka PC333 / PC2700) or 133MHz*2 (PC266 / PC2100). DDR is a 2.5 volt technology that uses 184 pins in its DIMMs. It is incompatible with SDRAM physically, but uses a similar parallel bus, making it easier to implement than RDRAM, which is a different technology.

Install and Configure the DNS Server

Install and Configure the DNS Server

Install DNS Server

1.      Click Start, point to Settings, and then click Control Panel.

2.      Double-click Add/Remove Programs.

3.      Click Add and Remove Windows Components.

4.      The Windows Components Wizard starts. Click Next.

5.      Click Networking Services, and then click Details.

6.      Click to select the Domain Name System (DNS) check box, and then click OK.

7.      Click OK to start server Setup. The DNS server and tool files are copied to your computer.

8.      Continue to the next step to configure the DNS server.


Configure the DNS Server Using DNS Manager

These steps guide you through configuring DNS by using the DNS Manager snap-in in Microsoft Management Console (MMC).

1.      Click Start, point to Programs, point to Administrative Tools, and then click DNS Manager. You see two zones under your computer name: Forward Lookup Zone and Reverse Lookup Zone.

2.      The DNS Server Configuration Wizard starts. Click Next.


        3. If the Wizard does not auto-start, right-click your server name object in the DNS Manager console and choose Configure your Server

4. Choose to add a forward lookup zone. Click Next. The new forward lookup zone must be a primary zone so that it can accept dynamic updates. Click Primary, and then click Next.

5.      The zone name must be exactly the same as your Active Directory Domain name, or, if on a stand-alone or workgroup environment - the same as the suffix for all of the network computers that are to register with this DNS server. Type the name of the zone, and then click Next.

6.      Accept the default name for the new zone file. Click Next.

7.      Choose to add a reverse lookup zone now. Click Next.

8.      Click Primary, and then click Next.

9.      Type the name of the zone, and then click Next. The zone name should match the Network ID of your local subnet. For example, if your subnet range is from 192.168.0.1 to 192.168.0.254, type 192.168.0 in the name value.

10.  Accept the default name for the new zone file. Click Next.

11.  Click Finish to complete the Server Configuration Wizard.

After the Server Configuration Wizard is finished, DNS Manager starts. Proceed to the next step to enable dynamic update on the zone you just added.

Enable Dynamic Update on the Forward and Reverse Lookup Zones (Optional - Recommended)

1.      In DNS Manager, expand the DNS Server object.

2.      Expand the Forward Lookup Zones folder.

3.      Right-click the zone you created, and then click Properties.

4.      On the General tab, click to select the Allow Dynamic Update check box, and then click OK to accept the change.

5.      Do the same for the Reverse Lookup Zone.

Enable DNS Forwarding for Internet connections

1.      Click Start, point to Programs, point to Administrative Tools, and then click DNS to start the DNS Management Console.

2.      Right click the DNS Server object for your server in the left pane of the console, and click Properties.

3.      Click the Forwarders tab.

4.      Check the Enable forwarders check-box.

5.      In the IP address box enter the IP address of the DNS servers you want to forward queries to - typically the DNS server of your ISP. You can also move them up or down. The one that is highest in the list gets the first try, and if it does not respond within a given time limit - the query will be forwarded to the next server in the list.

6.      Click OK.


DOMAIN NAME SYSYTEM (DNS)

DOMAIN NAME SYSYTEM (DNS)

What is DNS ?

 

            Domain Name System (DNS) is a database system that translates a

 

computer's fully qualified domain name into an IP address

 

 

What is Fully Qualified Domain Name ?

 

Ø      A fully qualified domain name (FQDN) is the complete domain name for a specific computer, or host, on the Internet

 

Ø      A fully qualified domain name consists of a host and domain name, including top-level domain

 

For example, www.sso.hcl.com is the fully qualified domain name for the sso directory of HCL corporate services.

 

 

What is a Zone ?

 

                        DNS data is divided into manageable sets of data called zone. It contains name and ip address information about one or more parts of a DNS domain.

 

 

Zone Types ?

 

Ø      Forward lookup zone

Ø      Reverse lookup zone

 

 

What is forward lookup Zone ?

 

A forward lookup zone searches for an ip address based on a provided host name. In general it resolves the host name to ip address of the computer.

 

 

What is reverse lookup Zone ?

 

A reverse lookup zone searches for the host name based on the ip address.In general it resolves the ip address to host name of the computer.


ACTIVE DIRECTORY

What is Active Directory?

 

Active Directory is a directory service. The term directory service refers to two things — a directory where information about users and resources is stored and a service or services that let you access and manipulate those resources.

 

Active Directory is a way to manage all elements of your network, including computers, groups, users, domains, security policies, and any type of user-defined objects. It melds several NT services and tools that have functioned separately so far — User Manager for Domains, Server Manager, Domain Name Server — and provides additional functions beyond these services and tools.

 

 

What are the Fundamentals of Active Directory?

 

  1. If a client wants to access a service or a resource, it does so using the resource’s Active Directory name. To locate the resource, the client sends a standard DNS query to a dynamic DNS server by parsing the Active Directory name and sending the DNS part of the name as a query to the dynamic DNS server.
  2. The dynamic DNS server provides the network address of the domain controller responsible for the name. This is similar to the way static DNS currently operates — it provides an IP address in response to a name query.
  3. The client receives the domain controller’s address and uses it to make an LDAP query to the domain controller. The LDAP query finds the address of the system that has the resource or service that the client requires.
  4. The domain controller responds with the requested information. The client accepts this information.
  5. The client uses the protocols and standards that the resource or service requires and interacts with the server providing the resource.


Active Directory Schema

The Active Directory Schema is the set of definitions that defines the kinds of objects—and the types of information about those objects—that can be stored in Active Directory. Because the definitions are themselves stored as objects, Active Directory can manage the schema objects with the same object management operations used for managing the rest of the objects in the directory. There are two types of definitions in the schema: attributes and classes. Attributes and classes are also referred to as schema objects or metadata.
