Packet Switching Networks Packet Switching - Packets are relayed across network along the best route available.
Repeater = Physical layer - takes a weak signal and regenerates it - doesn't translate or filter anything - can move packets from on physical media to another (i.e. can connect thinet to fiber-optic) - they are cheap - will pass a broadcast storm
Bridge = Data Link layer - does everything a repeater does - reduce traffic by segmenting the network by using a routing table- regenerate the signal at the packet level - not suited to WANs slower than 56K - will pass broadcast storms - read the source and destination of every packet - pass packet with unknown destinations - connect dissimilar networks (i.e. Token Ring and Ethernet)
Router = Network layer - does filtering and isolating traffic - forwards particular protocols to particular addresses (other routers) - connect network segments - not all protocols are routeable (LAT and NetBEUI) - are used in complex network situations because they provide better traffic mgmt. than brides - don't pass broadcast traffic.
Brouter = combines best qualities of both a bridge and a Router - can act like a Router for one protocol and bridge all of the others (nonroutable) - delivers more cost-effective

MCSE : Security Specialist

Security

Implement, configure, manage, and troubleshoot account policy.

These policies apply to user accounts. This security area contains attributes for:

  • Password policy: for domain or local user accounts, determines settings for passwords such as enforcement, and lifetimes.
  • Account lockout policy: for domain or local user accounts, determines when and for whom an account will be locked out of the system.
  • Kerberos policy: for domain user accounts, determines Kerberos-related settings, such as ticket lifetimes and enforcement.

 

Create and manage local users and groups.

A local user or group is an account that can be granted permissions and rights from your computer, where as Domain or global users and groups are managed by the network administrator. You can add local users, global users, and global groups to local groups, but you cannot add local users and groups to global groups.

By adding local users and groups you can limit thier ability to perform certain actions by assigning them rights and permissions. A right authorizes a user to perform certain actions on a computer, such as backing up files and folders. A permission is a rule associated with an object usually a file, folder and it regulates which users can have access to the object.

Local Users and Groups is not available on domain controllers. Use Active Directory Users and Computers to manage global users and groups.

To create a new user account

  • Open Computer Management.
  • In the console tree, in Local Users and Groups, click Users.
  • Click Action, and then click New User.
  • Type the appropriate information in the dialog box.
  • Select or clear the check boxes for:
    • User must change password at next logon
    • User cannot change password
    • Password never expires
    • Account is disabled
  • To finish, click Create, and then click Close.

A user name cannot be identical to any other user or group name, It can contain up to 20 uppercase or lowercase characters except for the following: " / \ [ ] : ; | = , + * ? < >

You can type a password containing up to 127 characters. However, if you're using Windows 2000 on a network that also has computers using Windows 95 or Windows 98, consider using passwords not longer than 14 characters. Windows 95 and Windows 98 support passwords of up to 14 characters.

To create a new local group

  • Open Computer Management.
  • In the console tree, in Local Users and Groups, click Groups.
  • Click Action, and then click New Group.
