Active Directory 2008-06-09 01:35:00 It is a centralized database where it contains the information about the objects like users, groups, computers, printers etc.AD is a centralized hierarchical Directory
Database.AD is a searchable Database.2003 O/S. when installed (gets installed as a stand alone server) to promoting to D.C. We have to install A.D.Domain Controller (D.C.):A server where A.D. is installed is called D.C.Functionality Read more:Active

IP-Address 2008-06-09 01:34:00 There are two versions of IP's1. IP version 4: offers IPs up to 4.2 billion (32 bit size)2. IP version 6: 128 bit size.IP address is used for identifying the system and provides communication.IP address is of 32 bits divided in four octets.Each Octet is of 8 bits, separated by a (.) dot.IP is a combination of Network ID & Host ID.Uses subnet mask to differentiate Network ID with Host ID.Subnet Read more:Address

Topology 2008-06-09 01:32:00 The way of cabling is called topology.The architecture of a network is called topologyThere are 2 Topologies :1) Network Topologies2) Logival TopologiesNetwork Topologies:E.g.: Bus, Star, Ring, and Mesh Topologies.Bus Topology:Components of Bus Topology:1. Co-axial cable (back bone cable)2. T- connectors3. BNC (British Network Connector)4. Terminator5. Patch cableDisadvantages of Bus:If anything g
Network Devices 2008-06-09 01:32:00 Hubs, Switches, Routers and NICs.HUB: Hub is a centralized device provides communication among systems when we have more that 2 computers we need to have a device called hub to interconnect.Disadvantage of a Hub:1)When we want to transfer some data from one system to another system.2)If our network has 24 systems the data packet instead of being sent only to the destined system it is being send to Read more:Devices
Types of Networks 2008-06-09 01:24:00 1)Local Area Network (LAN): Systems connected within the same geographical area is called LAN. A LAN can span 2 kilometers.Components of LAN:1. NIC (Network Interface Card)2. Cable – Co axial, cat5 or cat63. Hubs or Switches.2)Metropolitan Area Networking: MAN is a combination of LANs or WANS located and connected within the same city.Components of MAN:1. Router2. Brouter (Brouter is a combinati

Global Catalog 2008-06-16 06:49:00 It is a service responsible for maintaining information about the objects and serving the requests made by the users by providing the location of the object.Global
Catalog runs on the port number 3268.All types of queries are first heard on this port number and forward the query to port no.389 (LDAP’s).Maintains the complete information about the objects within the same domain and partial inform
Transfer of ROLES 2008-06-16 06:48:00 We can transfer the roles for some temporary maintenance issues on to ADC and again we can transfer back the roles onto DC.We can transfer the roles in two ways1. Command mode2. Graphical modeTransfer of roles through command:On DCGo to command prompt and type ntdsutilType: rolesConnectionsConnect to server (name of ADC ex.sys2)QTransfer schema masterTransfer RID masterTransfer infrastructure mast

Sharing 2008-06-17 19:12:00 In order to make a resource to be available over the network and to be accessed by network users we need to implement sharing.The moment we create a share on a server, server acts like a file server.Sharing

User Management 2008-06-17 18:53:00 User Account:User A/Cs is useful for assigning to the user to participate in the network.There are two types of accounts 50 Domain User Accounts51 Local User Accounts1. Domain User Accounts:These are created in the AD and they proved centralized management of users besides easy administration2. Local User Accounts:These can be created on the Local machines where the client works. Ex. 2000 prof. XP Read more:Management
Member Server 2008-06-17 12:36:00 A server, which is a part of DC, is called Member
Server. Server like WINNT, 2000 and 2003 can be configured as Member Server. Server, which is part of the Domain, is called Member Server.Member Servers are usedLoad balancing Load sharing form DCs A member server can be configured as any of the following servers. 1) Application service (oracle/SQL) 2) Mail server3) File server4) Print server 5) DN

Restoration 2008-06-19 07:13:00 There are two types of restoration:1)Non-authoritative restore2)Authoritative restoreRestoration of system state data can be done either authoritative or non authoritativeNon-authoritative restore is a normal restore useful when we have only one DC in the network. It does not increment the USN values of the objects after restoration. It uses older USN values only.1. Authoritative restore: This is
Backup 2008-06-19 07:08:00 It is a process of protecting user data or system state data on to separate storage devices.NT supported only one type of storage media, i.e. tapes.2000&03 supports tapes, floppies, HDDS (Hard Disk Drives), zip floppies, RSD (Remote Storage Devices)Back up utilities:The default backup utility provided by NT, 2000, 2003.NTbackup utility Comes along with the OS.

Scripts 2008-06-19 07:06:00 Scripts are useful to automate administrative tasks, which are routine. We can have startup and shutdown scripts, administrative scripts, login & logoff scriptsImplementing scripts using group policy:On DCCreate a folder (in D or E drive)Share it with full controlStart-run (notepad)Type wscript.echo “use the force read the source”Save the file as (filename.vbs) in the share folder we have Read more:Scripts
Folder Redirection 2008-06-19 07:04:00 It is useful when we have implemented mandatory profile for users as a result they cannot save anything on the desktop, unknowingly if they save, that saved desktop contents should be saved in another location we call it as folder redirection. (Users do not lose their data)Implementing folder redirection:On DCCreate a roaming profile for a userAnd convert it into mandatoryNote: create a new OU at Read more:Folder
