) It is a service of Microsoft used basically on windows network to resolve NetBIOS names to IP address and IPs to NetBIOS names.LMhosts: It is a static text file which contains NetB Read more:Domain Name
DHCP (Dynamic Host Configuration Protocol) 2008-06-03 03:04:00 IPs: (Internet Protocol
s)There are two versions in IP1. Version 4.02. Version 6.0IPs are of two types20 Static IPs21 Dynamic
IPsStatic IP: static IPs are IPs what an admin assigns to the computer manually. Which are not changeable.Dynamic IPs: Are the IPs, which are assigned by DHCP server, which are dynamic. i.e. not constant, changeable.DHCP: useful for extremely larger networks where we wan Read more:Configuration
FTP (File Transfer Protocol) 2008-06-12 06:53:00 It is a service of I.I.S. used for uploading or downloading large amount of files over internet or intranet. runs on a port no.21Creating an FTP site:On DCOpen E driveCreate a folder FTP rootCreate few files in that folderOpen I.I.S.Right click on FTP - new – FTP siteNext – FTP name – ex EDPFTP – Select IPNext - do not isolate users – browse the FTP folder we have created in E driveNext Read more:Protocol

ADVANCED 2008-06-24 23:48:00 Seizing of Roles: DC & ADC, when DC abruptly goes down, irreparable, no hopes of bringing back DC online we should seize the FSMO roles onto ADCPermanently configures ADC as DCImplementing: On ADCStart - run – cmd – (ntdsutil)RolesConnectionsConnect to server ADC’s server nameQSeize schema masterSeize Domain naming masterSeize RID masterSeize Infrastructure masterSeize PDC – q – q
Storage 2008-06-24 23:38:00 Basic Disks – partition – primary partition – extended – Logical partitionsDynamic disks: simple volume – spanned volume – stripped volume – mirrored volume – RAID – 5vBasic Disk:These are referred to partitions.Using basic disks we can create partitions like primary, extended, logical.Basic disks are useful for providing backward compatibility with older OS. Like DOS, 95, 98 etc
DISK MANAGEMENT 2008-06-24 23:34:00 2000 and 2003 uses a tool called Disk management for administering or managing Hard Disk DrivesUsing this we can create, delete, modify, partitions and volumes.We can also implement software rate, and disk analysis.To open Disk manager:Start – run – diskmgmt.mscOr right click on my computer – select manage.Creation of a primary partition:Start – run – diskmgmt.mscSelect free space (black
RIS (Remote Installation Service) 2008-06-24 23:22:00 It is a feature of 2000&2003 using which we can deploy operating system remotely on to the client machines.Requirements of RIS:Server side:AD, DNS, A static IP, DHCP, RIS, 2GB of free space with NTFS partitionClient side Requirements:Client machinePXE enabled NIC (Pre Boot execution Environment) or remote boot floppy.Installing RIS service:On DCStartSettings - control panelAdd/remove - add/r Read more:Remote

Routing 2008-06-21 11:22:00 It is a process of enabling communication between two different networks.There are two types of routers.1. Hardware router2. Software routerHardware router is a physical hardware device.Software router: A server with 2 NICs called software router.Ex: NT, 2000, 2003, UNIX can be configured as software routerA computer with 2 NICs is called a multihomed system.Requirements of the Software Router:DC Read more:Routing
