Flashcards in Windows Server Administration Deck (83)
In Windows AIK, the computer on which you install Windows AIK, create answer files, and manage the image deployment process.
In Windows AIK, a fully installed and configured computer that serves as a model from which you will create answer files and images.
A binary file with a .clg extension that contains all of the settings for an image file and their values.
Valid anser file names:
Applies the settings in the file during PE, before it copies files to the hard disk. So, use this one if you are doing any disk actions, like partitioning.
Configuration pass: windowsPE
• Options used during the Windows PE phase: PE screen res and the location of the installation log file
• Windows Setup options: selecting, partitioning, and formatting the system disk, name and location of the image file, product key, admin password
Configuration pass: offlineServicing
Applies unattended installation settings to an offline image, as well as enables you to add updates, hotfixes, language packs, and drivers to the image file.
Configuration pass: specialize
Computer-specific information: network configuration, international settings, domain name.
Runs after the generalize pass and system reboot / runs only when you execute the sysprep /generalize command.
Configuration pass: generalize
Specifies the settings that will persist after you run Sysprep.exe with the /generalize parameter. Running this causes all machine-specific settings to be removed from the computer configuration, like the SID and hardware settings, so you can create an image file.
Runs only when you execute the sysprep /generalize command.
Configuration pass: auditSystem
Applies unattended setup settings when the computer is running in the system context of an audit mode startup, before a user has logged on. Only runs when you configure it to start up in audit mode. This phase is an additional installation phase that occurs with a separate system startup after the OS installation and before Windows Welcome. OEMs and system builders typically use audit mode to install additional device drivers, applications, and other updates.
Configuration pass: auditUser
Applies unattended startup settings when the computer is running in the user context of an audit mode startup, after a user has logged on. Typically used to run scripts, applications, and other updates.
Configuration pass: oobeSystem
Applies settings during the first system boot after the Windows installation or the audit mode phase, also known as the Out-Of-Box-Experience (OOBE) or Windows Welcome. Runs only when you start the computer in OOBE mode.
MAP can run on the 32-bit versions of the following operating systems:
• Windows Vista
• Windows XP Pro with Service Pack 2
• Windows Server 2003 R2
A computer that provides services that support the primary functions of a network, working behind the scenes to facilitate user access to the computers that provide servers to them. Infrastructure servers are the ones that provide service to network administrators (not users). DHCP, DNS, etc.
Dynamic Host Configuration Protocol.
A service that automatically configures the IP address and other TCP/IP settings on network computers by assigning addresses from a pool (scope) and reclaiming them when they are no longer in use. An extension of BOOTP.
The three components of DHCP:
• A DHCP server application, which responds to client requests for TCP/IP configuration settings
• A DHCP client, which issues requests to a server and applies the TCP/IP configuration settings it receives to the local computer
• A DHCP communications protocol, which defines the formats and sequences of the messages exchanged by DHCP clients and servers
The DHCP standards define 3 different IP address allocations:
• Dynamic allocation - only to clients. The client is assigned an IP address for a specified length of time, and then it must renew it or the address goes back into the scope. (this is the default, at 6 days)
• Automatic allocation - The DHCP server permanently assigns an IP address. Reduces network traffic. An indefinite lease; good for networks where you do not often move computers to different subnets.
• Manual allocation - The DHCP server permanently assigns a specific IP address to a specific computer on the network (reservations). This is for computers that must have the same IP address all the time.
Designed to enable diskless workstations to retrieve an IP address and other TCP/IP configuration settings from network server. An admin had to manually enter the configuration parameters for each workstation on the server.
Used by clients to request configuration parameters from a DHCP server
Used by servers to offer IP addresses to requesting clients
Used by clients to accept or renew an IP address assignment
Used by clients to reject an offered IP address.
Used by servers to acknowledge a client's acceptance of an offered IP address
Used by servers to reject a client's acceptance of an offered IP address
Used by clients to terminate an IP address lease
Used by clients to obtain additional TCP/IP configuration parameters from a server.
DHCP communications are always initiated by:
DHCP IP address assignment process:
1) Client broadcasts DHCPDISCOVER
2) Any receiving servers reply with DHCPOFFER
3) Client broadcasts DHCPREQUEST with the info of the IP it wants to accept
4) Server receives it and adds it to its database.
5) Server transmits DHCPACK to acknowledge acceptance and completion of the exchange (if it assigned it to someone else, it sends a DHCPNAK and everything starts again)
6) Client broadcasts the IP using ARP to ensure no other system is using the IP address. If someone else is, it sends out a DHCPDECLINE to the server and starts again.
Automatic Private IP Addressing.
Used when there is no DHCP server available. Only works for computers on the same subnet.
DHCP IP address renewal process:
1) At 50% of the lease (renewal time or T1), the client sends unicast DHCPREQUEST messages to the DHCP server holding the lease.
2) At 87.5% of the lease (rebinding time or T2), the client sends broadcast DHCPREQUEST messages to try to get an IP address from any DHCP server.
3) The original server can respond with a DHCPACK to approve the renewal or a DHCPNAK to terminate the lease.
