1. Windows 2008 Adminstration

4. Windows 2008 Editions

5. Installation Preparations HCL (hardware Compatibility List) Gather hardware information and drivers Start with atleast –PIII processors (min: 133MHz.. Good luck) –Plenty of RAM Atleast 256Mb –SCSI-based disk subsystem (preferable)

6. Pre-installation Upgrade or Install ? FAT or NTFS –Dual-boot (FAT) –Domain Controller (NTFS) –ADS Security features (NTFS) Server mode: –Domain Controller Has domain info stored in ADS No more PDC/BDC. ADS -> Multimaster domain model – Member Server Do not hold ADS info. –Stand-alone Participates in a workgroup. Licensing –Per Seat CAL for each client computer. Not monitored by server –Per Server CAL defines number of connections to server

7. Installing the Server Upgrade from older versions Prepare boot disks and install Install from the network where files are located Components to Install Configuring Network connectivity

8. Configuring Client Creating user account Creating Shared folders –Everyone full control (default) Permissions on shared folders Client Configuration –Use ‘ Client for Microsoft networks ’ –Select ‘ log on to NT domain ’ and type the domain name. Log in as user on client –Browse the network to see the server and the ADS –If server does not show up, use ‘ find computer ’ option to detect the newly installed server.

9. Server Administration Security vs. Productivity User accounts –Unique SID (Security ID) across space & time No two users will ever have the same SID, even it a user is deleted and recreated –Creating, modifying and deleting users User Groups –Members inherit permissions –Groups can be members of groups Creating a hierarchy of group permissions

10. Groups Two types: –Built-In Fixed and cannot be deleted.Has pre-assigned set of permissions. P:291 Cannot be made members of other groups –Other groups you create can be added. To disable – remove all members –User-defined Administrator definable group objects. Scope: –Universal »Exits thro ’ the org (made of many individual domains) »Can contain members from any other domain –Global »Contains members only from one domain. »Can assign permissions across multiple domains. –Domain local »Exists only within a single domain Groups –Security –Distribution »Only to maintain distribution lists. Has no security impact. »For email apps (Exchange 2000).

11. Shared folders Drives and folder shares –Both NTFS and FAT –Permissions on folder/files within share that are separate from permission on share itself NTFS only. Most restrictive permissions apply for shared folders. –R&d group has ‘ R ’ on folder ‘ test ’ –R&d has ‘ Ch ’ on subfolder within test. –Effective for R&d is ‘ R ’ – most restrictive Users receive permission based on the groups of which they are members and these are cumulative – file systems –Jdoe has ‘ R ’. Jdoe is member of ‘ emp ’ with ‘ Ch ’. –Jdoe ’ s cumulative is ‘ RCh ’ NO ACCESS/DENY overrides everything.

12. Permissions Rules: –When shared folder permissions conflict with file or folder permissions, the most restrictive one always win. –File System Permissions are cumulative, taking into account permissions assigned to users and groups as well as files and folders. –When permission conflict occurs, the NO ACCESS permission always win. Default: –Everyone has read permissions. –More restrictive rights assigned to sub folders.

13. Mapping Network drives To view shared folders –Use Network neighborhood or My network places. To simulate disk drive (mapping) –Right click and choose Map Network drive –DOS Command line Net use drive_letter: UNC_for_share (universal naming convention) Net use g: \\server_name\shared_folder_name\\server_name\shared_folder_name

14. What is Printing really. Print job: –Binary data send from a n/w w/k to a n/w printer. –W/k responsible for formatting the data print drivers Different from OS to OS –Jobs sent to n/w through captured ports. N/w client s/w redirects printer port (LPT1) to the n/w printer. –Jobs stored in queues. Managed as FIFO. –Print servers Forwards jobs from print queue to the actual printer. App: -> OS -> print driver (formatting) -> n/w client sends to captured port -> print queue -> print server -> printer.

15. Windows 2k3 printer setup Add printer to printer folder –Choose sharing Options: –Printer pooling: High-throughput requirements. Set of identical printers, connected to single queue, appearing as one printer. First available printer services the job. –Permissions from the security tab. Three types –Print, Manage Printers & Manage Documents –2k3 Server can store print drivers for different OS/platforms. Distributed and installed the first time client computers use the printer.

16. Backups Making regular and reliable backups Not just files –Files have attribute bits that define permissions, owners, backup status

17. Types of Backup File/Directory: Selected files and directories Full / Image: Everything including programs and settings Shadow: make a copy to another location when the user makes changes Incremental: –backup includes all the files that have changed since the last backup Differential: –those files changed since the last full backup, so any changed file appears only on one differential backup. Daily: –all files modified on a given day

18. Backup strategies –Many different Possibilities: One possible method is Normal full backup once a week and differential every night –Requires only two tapes for restore –Requires more media Normal Full once a week and incremental every night. –Requires multiple tapes to restore –Requires less media

19. Backup in win2k3 Not the best program. Third party software preferable –Symantec, ArcServe, Backup Exec, etc. –Added functionalities Manager tape libraries, media pools Win2k3 program helps –Backup files, restore and prepare for system state rebuilt in case of catastrophes –Backup/restore to/from: Network, commercial backup sites, Tapes, Optimal Continuous Data Protection (CDP) –Real time back to another site

20. Backup Management Policies Backup creation policies –What to backup, how frequently, etc. Restoration and Retention policies –Restoration test, audit –How long to retain Media Storage Location policies –Legal requirements on how certain type of data is stored

21. Server 2003 Services Important windows 2003 services –DHCP Defines scope (range) of ip to be allocated –Fixed ip – servers –DHCP – clients, printers DNS –Create domains (info472.info.net) and subdomains (accounting.info472.info.net) –Multiple servers can be used to manage separate portions of the DNS namespace (zone) –Integral part of ADS RRAS –Access to n/w resources through dialup/ISN using modems (RAS) –RRAS for VPN through secure tunnels

22. More win2k3 services IIS –Provides web, FTP, SMTP, NNTP services Unix/DOS-style ftp sites, web services with front page extensions, mail protocols, NNTP usenet news groups Cluster services: –Combine servers into clusters Load balancing –Share tcp/ip based services (web) Fail over –Share common disk array, server takes over control of services when other server fails Terminal Services: –Virtual windows machines Clients connecting and running applications of server as if they were local apps. One powerful server and software for all users. Remote management of server
