  1. Windows 2000 Server Week Three Kidane Sengal

  2. Managing Network Interoperability Chapter Nine Kidane Sengal

  3. Introduction • Network Card • Network Protocols • TCP /IP • Network Services Kidane Sengal

  4. Network Protocols • TCP/IP • NwLink IPX/SPX/NetBIOS • Novel Netware • NetBEUI • Nonroutable protocol • ApplTalk • Apple Micintosh • DLC • Printers and IBM mainframes Kidane Sengal

  5. Transmission Control Protocol/ Internet Protocol (TCP/IP) • Most commonly used protocol • Originally Developed in 1970s for department of defense (DOD) as the way connecting dissimilar networks • Industry standard Kidane Sengal

  6. Benefits of TCP\IP • Most commonly used almost all networks • Scalable • Provides routing service • Fault tolerant • Protocol companion • DNS • DHCP Kidane Sengal

  7. TCP/IP Architecture Kidane Sengal

  8. Telnet FTP SMTP DNS RIP SNMP TCP UDP IP ARP IGMP ICMP TCP/IP Kidane Sengal

  9. Guidelines for TCP\IP Configuration • IP address must be unique to the internet • Network address can’t start with 127 • Loop back capability • Can’t have network address of 255 (all 1s) • Reserved for broadcast transmission • Can’t have address of 0( all 0s) Kidane Sengal

  10. IP Address • IP address uniquely Identify Computer in the network • Four field of 32-bit address • Network address and host (local address) Kidane Sengal

  11. Classes of IP address • Class A • Class B • Class C Kidane Sengal

  12. IP Classes Kidane Sengal

  13. Subnet Mask Kidane Sengal

  14. Domain Name Service (DNS) Severs • Resolve host name to IP address • Host file • WINS Servers • NetBIOS name resolution • When you try to access a computer using the NetBIOS name Kidane Sengal

  15. WINS Servers • Used to resolve Network Basic Input/output ( NetBIOS) names to IP address • Mainly for Windows NT 4 • Methods of resolving NetBIOS name • Broadcast • Through a server • LMHOST File Kidane Sengal

  16. NetBIOS Resolution • Local NetBIOS name cache • NetBIOS to IP address mapping If not resolved • Clients send name query to primary WINS server( If not resolved after three attempt) • Clients send to Secondary WINS • If not resolved • Network Broadcast initiated to locate the remote computer….. Kidane Sengal

  17. Testing IP Configuration • Ipconfig • /all • /release • /renew • /flushdns • Ping • Uses to verify connection • ……….> Kidane Sengal

  18. NWLink IPX/SPX/NetBios • Microsoft implementation of Novell Internetwork packet exchange/Sequenced packets exchange (IPX\SPX) protocol stack • Windows 2000 adds NetBIOS support • Transport protocol • NWLink and client service for network (CSNW) on client • Gateway service for Netware (GSNW) on servers Kidane Sengal

  19. Configuring NWLink IPX/SPX • Network Number • to identify Print and file servers using IPX • Frame type • Have t o have the same frame type to communicate two networks • Default is auto detect • Exercise 9.3 Kidane Sengal

  20. NetBIOS Extended user interface (NetBEUI) • OS/2 and LAN Manager operating system • Easy to install • No config requirement • Less overhead than TCP/IP and IPX/SPX • Better Performance • Uses less memory than TCP/IP & IPX/SPX • Not Routable Kidane Sengal

  21. Network Bindings • Communication between network adapter and network protocols that are installed Kidane Sengal

  22. Configuring Network Services • On Windows 2000 network only Windows 2000 server computer can act as a DHCP, DNS and WINNS server • DHCP • Have to have networking service installed • Have a static IP address configured • Have valid range of IP address that can be assigned to DHCP client Kidane Sengal

  23. DHCP Implementation • DHCPDISCOVER • IP address request client • DHCPOFFER • IP address offer from DHCP server • DHCPREQUEST • IP selection • DHCPPACK • Acknowledgment send with DNS and default Gateway address << ROSA>> ……> Kidane Sengal

  24. DNS • Resolves host name to IP addresses • DNS uses fully qualified domain name (FQDN) to resolve host name to IP address • DNS is hierarchical structure Kidane Sengal

  25. DNS Name Resolution • DNS clients queries DNS server for name resolution • If DNS server can resolve the query DNS server response to DNS client • Iterative query • If DNS server can’t resolve the query DNS server contact other DNS server • Recursive query Kidane Sengal

  26. Types of DNS queries • Forward lookup • requests to map FQDN to IP address • Reverse lookup • request to map IP address to FQDN Kidane Sengal

  27. The End Q/A ? Kidane Sengal

  28. MANAGING Web Services Chapter 10 Kidane Sengal

  29. Internet Information Services (IIS) • Windows 2000 comes with IIS • Which allows to create and manage web sites • Provides wide range of options for • Configuring The content • Performance • Access controller • full-featured Web server, designed to support heavy Internet usage Kidane Sengal

  30. Services Installed as a Part of IIS • File Transfer Protocol FTP • Hypertext Transfer Protocol (HTTP) • Simple Mail Transfer Protocol (SMTP) • Network News Transfer Protocol (NNTP) Kidane Sengal

  31. Internet Service Manager • Default FTP • Default Website • Administration Website • Default SMTP virtual server • Default NNTP virtual server • ------- Kidane Sengal

  32. Website Properties • Website • website identification, connections and logging • Operators • Users and groups to manage the website • Performance • Bandwidth, memory and processors • ISAPI Filters • Internet server application programming interface f • Home Directory • Access permission, content control & app settings Kidane Sengal

  33. Website Properties Cont.. • Documents • Default documents users will see if they access your web site • Directory Security • Secure communication & IP address restriction • HTTP headers • Hyper text markup language headers of the website • Custom Errors • Customize web browsers error • Server Extension • Publishing controls for Front page options Kidane Sengal

  34. IIS Properties • Performance Tuning • Hits per day • Bandwidth Throttling • Limit the amount of bandwidth that can be used by the web site • Process Throttling • Specify the amount of CPU processing that can be used for the website Kidane Sengal

  35. Troubleshooting Web Site Access • Problem can be caused by • Access permission • Improperly configured home folder • Default document • Wrong TCP port Kidane Sengal

  36. Administrating Terminal Services Chapter 12 Kidane Sengal

  37. Terminal Services • Remote Administration • Eliminate the cost of hardware upgrade • Proper licensing • Terminal server includes • Managing utilities • Configuration utilities • Client creator tool for managing the server and clients Kidane Sengal

  38. Terminal Services • Many clients can access the server through terminal emulation software • Personal computers • Windows CE-based Handheld PCs or • Traditional clients • Clients can access Terminal Services through TCP/IP from local connection or WAN connection Kidane Sengal

  39. Terminal Services • Some of the Clients that can act as a Terminal services client • MS-DOS- based clients • Windows for Workgroups clients, version 3.11 or later • Windows based terminals (Windows CE devices) • Unix terminals • Macintosh clients Kidane Sengal

  40. Terminal Service Modes • Remote administration mode • Administrators perform administrative stuffs virtually • Only the remote administration component of terminal service is installed • Maximum of two concurrent connection • No additional licensing is required • No server license required Kidane Sengal

  41. Application Administration Mode • Users have remote administration to applications running on the server • GUI is transmitted to a remote user • Client sends keyboard and mouse signals to the server • Manages unique client sessions transparently • Must use license server and each client computer must have terminal service client access license and Windows 2000 client Access license Kidane Sengal

  42. Benefit of Terminal Service • Wider deployment of Windows 2000 • Simultaneous operation of both the client software and a stand-alone operating system • Remote Administration of the server • Simplified application deployment Kidane Sengal

  43. Terminal Service Components • The Terminal Service Server • The Remote Desktop Protocol • The Terminal Service Client Kidane Sengal

  44. The Terminal Service Server • Most terminal service operation • Send only screen information to the client • Keeps track of active session • On application mode all applications run on the server Kidane Sengal

  45. The Remote Desktop Protocol • Remote Desktop Protocol (RDP) automatically installed • One RDP per connection per network card adapter • You can set encryption setting and permission • You can limit the amount of time clients session can remain active Kidane Sengal

  46. The Terminal Service Client • Uses thin–client technology to deliver the Windows 2000 Server Desktop to the user • Clients need only to establish a connection with the server • Display GUI that the server sends • Little overhead on the client part • Able to run on older machines Kidane Sengal

  47. Planning Terminal Services Configuration • Determining Client Application • Per computer basis rather than per user • Window on Windows (WoW) In order to run 16-bit applications • Determining Hardware Requirement • Server • Requires at least 128MB RAM + 10 -20 mb Per connection • High performance bus architecture • You should consider SCSI • High performance network adapter • Client • Windows based terminal devices (embedded) • Intel and alpha based computers • Macintosh and Unix based computers with addition third party software • Determining Proper licensing requirement Kidane Sengal

  48. Determining Proper Licensing Requirement • Terminal services uses its own licensing mode. • Terminal client must receive a valid licensing from Terminal Service license Server before logging • Only application server mode • A enterprise License server • Can serve on any Windows 2000 domain but can’t serve on workgroups or Windows NT • A Domain License server • Can server only in the same domain • In Windows 2000 domain license must be installed in DC • In work group and Windows NT can be installed on memeber server Kidane Sengal

  49. Managing Remote Network Connections Chapter 13 Kidane Sengal

  50. Remote Network Connection • Remote Access Service (RAS) servers • Allow to connect directly through • Modem ISDN adapter • Virtual Private Network (VPN) • Allow users to connect through • Private network or internet connection Kidane Sengal
