CHKNTFS

   The usage to disable a drive is

chkntfs /x <drive letter>:
e.g. chkntfs /x f: would exclude the check of drive f:

To set the system back to checking all drives just type chkntfs /d
 

CIDR       Classless Interdomain Routing

    Also known as supernetting, CIDR may be used to consolidate several class C network addresses into one logical network. CIDR is described in RFC1518/1519. To use supernetting, the IP network addresses that are to be combined must share the same high-order bits, and the subnet mask is "shortened" to take bits away from the network portion of the address and add them to the host portion.

    This is best explained with an example. The class C network addresses 199.199.5.0, 199.199.6.0, and 199.199.7.0 can be combined by using a subnet mask of 255.255.252.0 for each:

NET     199.199.5         (1100 0111 . 1100 0111 . 0000 0101.0000 0000)
NET     199.199.6         (1100 0111 . 1100 0111 . 0000 0110.0000 0000)
NET     199.199.7         (1100 0111 . 1100 0111 . 0000 0111.0000 0000)
MASK 255.255.252.0  (1111 1111 . 1111 1111 . 1111 1100.0000 0000)
    When routing decisions are made, only the bits covered by the subnet mask are used, thus making these addresses all appear to be part of the same network for routing purposes. Any routers in use must also support CIDR and may require special configuration.

CIFS     Common Internet File System

A file sharing protocol: an updated version of the Server Message Block (SMB) authentication protocol.

CLSID     Class Identifier

A universally unique identifier (UUID) that identifies a COM component. Each COM component has its CLSID in the Windows Registry so that it can be loaded by other applications.

COM        Component Object Module

An object is a software construct that encapsulates or packages some data and some public methods that operate on that data. COM objects completely hide their data and expose their methods through a construct called an interface.

There are also COM components (also called simply component objects). A component object is a reusable software unit that encapsulates or packages the manufacturing of a specific class of COM object. A COM object class specifies an open-ended set of behaviorally identical COM objects that is uniquely identified for all programs and all time (by a Class ID => CLSID).

Component objects are housed in a COM Server. The server executable is registered (or published) in a system registry to act as the creation agent for COM object instances of the COM Component. The server contains one or more Class Factories used for the creation of COM objects. Class factories are themselves COM objects that expose the IClassfactory[2] interface. However, as an integral part of the server housing, class factories are typically not full-fledged component objects.

Credential Caching       Cache de credencial

    By default, Windows NT caches the logon credentials for the last user that logged on interactively to an NT system. One reason this feature is provided is so that a user can still log on to the system, even if their system is disconnected from the network or none of the domain controllers are available.
  The credential cache is protected, but it can be disabled completely if the environment requires a high level of security. To disable credential caching, change the following entry:

Hive:       HKEY_LOCAL_MACHINE
Key:        SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Name:       CachedLogonsCount
Data Type:  REG_DWORD
Value:      0
