In a domain, computers can share physical proximity on a small LAN or can be located in different corners of the world.6Workgroup vs. DomainWorkgroup:A logical grouping of networked computers that share resources such as files and printers.Called Peer-to-Peer network because computers can share resources as equals, without a dedicated server.In a Workgroup, each server and each workstation maintains a local database which contains user accounts, other resources, and security information for that computerIn a Workgroup, the administration of user accounts and resource security is decentralized:A user must have a user account on each computer the user needs to accessAny change to a user account must be made on each computerConvenient for small groups (≈ 10 computers)7Win NT vs. Win 2000 domainsWin NTBefore the installation, you need to know whether the server will be a DC or a MS.If you install as a MS, you need to reinstall the OS to make the server a DC.Win 2000:You install as Stand-Alone or Member ServerAfter installation, you can decide to make the server a DC or not.Domain ControllerMember ServerStartStand-Alone ServerMember ServerStartDomain ControllerNon Domain ControllerNon Domain Controller8File Systems: FAT vs. NTFSDisks can be formatted using, basically, two types of formatting systems: FAT & NTFSWindows 2000 supports both File Allocation Table (FAT) and NT File System (NTFS)FAT:Is an older file system designed for computers with small disk storageOffers less data security than NTFSLong file names (<= 256 characters)File-level and directory level securityData compressionDisk quotas management for disk usage controlFile encryptionNeeded for AD servicesNTFS FeaturesFAT16 FAT32 NTFSSupported by MS-DOS, Win 3.x and Win 95 OSR1 ?YES NO NOSupported by Win 95 OSR2 & Win 98?YES YES NOSupported by Win NT 3.51 & Win NT 4.0?YES YES YES (NTFS 4.0)Supported by Win 2000?YES YESYES(All ver.)9Licensing modesClient Access Licenses (CAL) needed to access Win 2000 serversTwo Licensing modes: Per-Server and Per-SeatPer-Server: CALs are assigned to a particular serverYou must have at least as many CALs as the maximum number of workstations used to connect at the same timePer-Seat:CALs are assigned to workstationsYou must have a CAL for each workstation used to connect.Win 2000 ServerWin 2000 ServerWorkstation Workstation Workstation Workstation WorkstationPer-Server:Need 3+3=6 CALs if 3 concurrent connectionsPer-Seat:Need 5 CALs to have all Workstation capable to connect all timeBest choice if users require frequent access to multiple servers10Hands-onSee Hands-on exercises (hard copies)11Summary QuestionsYou are setting up a network for a small company that uses only five computers. All users and their computers are located in the same office. All computers should be on the network. The company does not require centralized security. Users share files regularly and share the same printer. You need to implement this network for as little expense as possible. Which solution should you use?a) Configure one of the computers with Microsoft Windows 2000 Server and Active Directory services. Configure the remaining computers with Microsoft Windows 2000 Professional. Join each computer to the same domain.b) Configure each computer with Windows 2000 Professional and join them to the same workgroup.c) Configure one of the computers with Windows 2000 Server and Active Directory services. Configure the remaining computers with Windows 2000 Professional. Join each computer to the same workgroup.d) Configure each computer with Windows 2000 Professional and join them to the same domain.12Summary QuestionsYou are setting up a network for a company that uses about 100 computers. All computers should be on the network. The company requires centralized administration. Each user should be able to use a single logon process to gain access to network resources, such as file, print, and application resources. The company expects to grow steadily and wants to be able to add computers and users as necessary, without having to redesign the network. Which solution should you use?a) Create a parent domain and join all computers running Microsoft Windows 2000 Server to that domain. Create a workgroup and join all computers running Microsoft Windows 2000 Professional to that workgroup.b) Create a workgroup and join all computers to that workgroup.c) Create a parent domain and child domains as
