Chapter 1The Microsoft Windows 2000 Platform
Windows 2000 Server. Windows 2000 Advanced Server. Active Directory directory services. Integrating Active Directory directory services with Windows 2000 makes all shared printers in your domain available as objects in Active Directory directory services. Personalized Menus can be activated to keep track of the programs you use and to update the Programs menu so that it presents only the programs that you use most often. Applications that you use less frequently are hidden from normal view, making the Start menu easier to use. Improvements to the user interface, a graphical scheduling utility, improved hardware support, and support for ACPI. Microsoft Management Console (MMC), group policy, DNS dynamic update protocol, Active Directory directory services, Windows Management Instrumentation (WMI), Remote Storage, Windows Script Host, Indexing Service. Chapter 2Installing Windows 2000
Verify that the hardware components meet the minimum requirements for Windows 2000. Also, verify that all of the hardware components that are installed in the new computers are on the Windows 2000 HCL. If a component is not listed, contact the manufacturer to verify that a Windows 2000 driver is available. Start the computer by using the Setup boot disks. When prompted, insert the Windows 2000 Workstation CD-ROM, and then continue Setup. You need the DNS domain name of the domain that you are joining. You must also make sure that a computer account for the member server exists in the domain or you must have the user name and password of a user account in the domain with the authority to create computer accounts in the domain. A server running the DNS Service and a domain controller in the domain you are joining must be available on the network. Use a disk partitioning tool to remove any existing partitions, and then create and format a new partition for the Windows 2000 installation. Locate the path to the shared installation files on the distribution server. Create a 500 MB FAT partition on the target computer (1 GB recommended). Create a client disk with a network client so that you can connect from the computer, without an operating system, to the distribution server. Chapter 3Configuring the DNS Service
Record your results in the following table.
Domain name space The domain name space provides the hierarchical structure for the DNS distributed database. Zones Zones are used to divide the domain name space into administrative units. Name servers Name servers store the zone information and perform name resolution for their authoritative domain name spaces. Installing multiple name servers provides redundancy, reduces the load on the server that stores the primary zone database file, and allows for faster access speed for remote locations. A forward lookup query resolves a name to an IP address. A reverse lookup query resolves an IP address to a name. Configure a name server as a root server only if you will not be connecting to the Internet or if you are using a proxy server to gain access to the Internet. A name server must have at least one forward lookup zone. A forward lookup zone enables name resolution. A reverse lookup zone is needed for troubleshooting utilities, such as Nslookup, and to record names instead of IP addresses in IIS logs. Dynamic DNS allows automatic updates to the primary server's zone file. In DNS, you must manually update the file when new hosts or domains are added. Dynamic DNS also allows a list of authorized servers to initiate updates. This list can include secondary name servers, domain controllers, and other servers that perform network registration for clients, such as servers running WINS and the DHCP Service. Chapter 4Implementing Active Directory Directory Services
What is the one Sysvol location requirement? Sysvol must be located on a Windows 2000 partition that is formatted as Windows NT file system (NTFS). What is the function of Sysvol? Sysvol is a system volume hosted on all Windows 2000 domain controllers. It stores scripts and part of the Group Policy objects for both the current domain and the enterprise.
What selections are listed under domain? Builtin, Computers, Domain Controllers, Foreign-Security-Principals, LostAndFound, System, and Users.
That you have a partition or volume formatted with NTFS. That you have adequate hard disk space to store the directory. That the system time and time zone settings are accurate. That you have a DNS server, if you are not going to let Active Directory directory services configure a DNS server while running the wizard. Change from mixed mode to native mode. To do this, you use the Active Directory Domains and Trusts snap-in, which you start from the Administrative Tools menu. A domain controller and a global catalog server. These two components can be on the same computer. It is likely that you haven't configured sites for your network and that domain controllers that are located across the slow WAN link are occasionally authenticating users. Create a site for your main office and a site for your remote office. Create a subnet object for each network, and associate the subnet with the appropriate site. Make sure that both sites are in the default site link, DEFAULTIPSITELINK. Site Link AD: Cost 2 Site Link BD: Cost 2 Site Link CD: Cost 2 Site Link ED: Cost 1 The cost value is arbitrary. It is only important that the cost of site links be in the same proportions as above. Chapter 5Administering Active Directory Directory Services
By default, when can a user log on? All hours on all days are allowed by default.
Were you able to successfully log on as User1? Why or why not? Yes, because User One has access to the network 24 hours a day, 7 days a week. Were you able to successfully log on as User Two? Why or why not? It depends on the time set on your system clock. If it is between 6:00 AM and 6:00 PM, you should not be able to log on. If it is between 6:00 PM and 6:00 AM, you should be able to log on.
Were you able to successfully add the Managers global group to the universal group? Why or why not? Yes. A global group can be a member of a universal group. Was the Inventory domain local group available for you to add to the universal group? Why or why not? No. A domain local group cannot be a member of a universal group.
Why are all permission check boxes for some groups blank? Additional permissions are present, but you cannot view them in this dialog box. To see the unavailable permissions, click the Advanced button. Are any of the default permissions inherited from the domain, which is the parent object? How can you tell? The permissions that are assigned to Enterprise Admins are inherited from the parent object. The check boxes for inherited permissions are shaded.
The Permission Entry For Security dialog box appears. What object permissions are assigned to Account Operators? What can Account Operators do in this OU? The permissions that are assigned to Account Operators are Create User Objects, Delete User Objects, Create Group Objects, Delete Group Objects, Create Computer Objects, and Delete Computer Objects. Account Operators can only create and delete user accounts groups, accounts, and computer accounts. Do any objects within this OU inherit the permissions assigned to the Account Operators group? Why or why not? No. Objects within this OU do not inherit these permissions. The dialog box shows that permissions are applied on this object only.
What user objects are visible in the Security OU? The Secretary and Assistant user accounts. Which permissions allow you to see these objects? (Hint: refer to your answers in the preceding exercise.) The Assistant user account automatically belongs to the Authenticated Users built-in group, which has the Read permission for the OU. Attempt to change the logon hours for Secretary. Were you successful? Why or why not? No. The Assistant user account does not have the Write permission for this object. Attempt to change the logon hours for Assistant. Were you successful? Why or why not? No. The Assistant user account does not have the Write permission for this object.
Were you successful? Why or why not? Yes. The Assistant user account has been assigned the Full Control permission for all objects in the OU. This includes the permission to change the logon hours. Were you successful? Why or why not? No. The Assistant user account has been assigned no permissions for the Users OU.
Place user accounts (A) into global groups (G), place global groups into domain local groups (DL), and then assign permissions (P) to the domain local group. The global catalog contains the access permissions for an object. If users do not have the Read permission for an object, they cannot view or locate the object. Permissions that are assigned directly to the object remain the same. The object also inherits permissions from the new OU. Any permissions that were inherited from the previous OU no longer affect the object. Right-click the OU and click Delegate Control to run the Delegation Of Control wizard. Assign control of the OU to the user and limit the user's control to computer accounts within that OU. No, you must also have the Create Organizational Unit Objects permission to create an OU. You should also have the List Contents permission to view the objects in the container. User accounts must have unique names within the OU or container in which you have created them. Computer accounts must have unique names within the Active Directory forest. Chapter 6Managing Desktop Environments with Group Policy
Were the following restrictions enforced? Why or why not? No Run command on the Start menu. No access to Display icon in Control Panel. No My Network Places icon on the desktop. No Map Network Drive or Disconnect Network Drive on the Tools menu in Windows Explorer. Yes. The restrictions should be enforced for the Administration OU and the User One account is located in this OU.
Were the following restrictions enforced? Why or why not? No Run command on the Start menu. No access to Display icon in Control Panel. No My Network Places icon on the desktop. No Map Network Drive or Disconnect Network Drive on the Tools menu in Windows Explorer. No. None of the four were in force for ADAmin because the user account is located in the Users OU.
Were the following restrictions enforced? Why or why not? No Run command on the Start menu. No access to Display icon in Control Panel. No My Network Places icon on the desktop. No Map Network Drive or Disconnect Network Drive on the Tools menu in Windows Explorer. No. Group Policy has been removed.
GPOs store Group Policy information in a Group Policy Container and in a Group Policy Template. GPOs are implemented in the following order: site, domain, and then organizational unit. If the Software Development group had its own OU, you would create a GPO at the domain level, containing the required restrictions. You would then set the Block Policy Inheritance option at the Software Development OU. If all user accounts, including the Software Development group, were in the Users container, you would create a GPO at the domain level, containing the required restrictions. Next you would create a security group and add all of the Software Development group accounts to this group. Then you would deny Apply Group Policy permission on the discretionary access control list of the GPO for the new security group. Chapter 7Managing Software by Using Group Policy
The two new technologies are the Windows Installer and Windows 2000 Software Installation And Maintenance. Microsoft Word 2000 would be assigned in a GPO at the domain level. Microsoft Excel 2000 would be assigned in a GPO at the accounting department's organizational unit and would also be published in a GPO at the domain level. If the application were required for all users, regardless of which computer they log on to, you would assign the application to computers. You would deploy the new version as an optional upgrade. This will allow users to continue to use the previous version until they are able to upgrade to the new version. Chapter 8Managing File Resources
Who is the current owner of the Owner.txt file? The Administrators group.
Who is the current owner of Owner.txt? The Administrators group. Who is the current owner of Owner.txt? The User Four user account.
Windows 2000 displays the Add New Quota Entry dialog box. What are the default settings for the user you just set a quota limit for? Limit disk space to 10 MB and set warning level to 6 MB. These are the default settings that are selected for drive C.
What happens? The Notepad message box informs you that access is denied.
This can be accomplished by publishing the marketing documents and putting the research and development documents in a hidden shared folder. Install Dfs on one computer and create child nodes out of all of the shared folders. Windows 2000 supports disk quotas, which allow administrators to dynamically change the quotas. The disks need to be defragmented. This should be done at night or during the weekend to minimize the impact on productivity. Chapter 9Configuring Remote Access
L2TP supports more types of internetworks, it supports header compression, and it cooperates with IPSec for encryption. The settings are whether you want to allow others who use the computer to use the connection (access to the connection) and whether you want to allow other computers to access resources through this port (sharing the connection once it is established). By storing remote access policies on the remote access server, policies can vary according to the capabilities of the server. For example, servers having different sizes of modem pools can have different profile settings for multilinking. The access permission setting on the policy is overridden in a mixed-mode domain because the user dial-in setting, Control Access Through Remote Access Policy, is not available. Policy conditions and profiles are still effective. The profile must still match the settings of the connection attempt. For example, the profile may specify that another authentication protocol be used instead of CHAP. If this is the case, this attempt would be denied. Chapter 10Supporting DHCP and WINS
Are there any entries for DHCP? No. Are there any entries for DHCP? Yes, the DHCP tool was added to the Administrative Tools menu when the DHCP Service was installed.
You can use the DHCP console to display the total number of scopes and addresses on the server, the number of available addresses versus the number of depleted addresses, and the number of leases being processed per second. The DHCP Service is not authorized to operate in the domain. A member of the Enterprise Admins group must authorize the DHCP server before the DHCP Service will start on the member server. When a DHCP server that is a member of a workgroup starts, it sends a broadcast message. If the DHCP server receives a response from a DHCP server in a domain, the DHCP server that sent the broadcast message assumes that it is unauthorized on the network. If the DHCP server receives a response only from workgroup DHCP servers, the DHCP server that sent the broadcast message determines that it can operate normally. Create a new scope with the additional addresses, and then combine the two defined scopes into a superscope. You can use DHCP option classes to manage configuration details for DHCP clients within a scope. Windows 2000 supports two types of option classes: vendor-defined and user-defined classes. The client can use Automatic Private IP Addressing to generate a unique IP address in the range 169.254.x.y. You can configure a WINS client with as many as 12 WINS servers. The additional WINS servers provide an extra measure of fault tolerance in the event that the primary and secondary WINS servers fail to respond. Chapter 11Managing Disks
You can leave the disk as a basic disk and then create a combination of primary partitions (up to three) and logical drives in an extended partition; or, you can upgrade the disk to a dynamic disk and create five 2-GB simple volumes. Add the Computer Management or Disk Management snap-in to an MMC console. You have the option to focus the snap-in on the local computer or another computer. Type in the name of the computer you want to administer remotely. You can create striped volumes on dynamic disks only. The option to create a partition rather than a volume indicates that the disk you are trying to use is a basic disk. You will need to upgrade all of the disks that you want to use in your striped volume to dynamic disks before you stripe them. The existing volume is not formatted with NTFS. You can extend NTFS volumes only. You should back up any data on the existing volume, convert it to NTFS, and then extend the volume. Only Windows 2000 can read dynamic disks. Chapter 12Implementing Disaster Prevention
All disks that will be a part of the fault-tolerant volume must be upgraded to dynamic storage. You would restart the computer and select Safe Mode from the Advanced Options menu. When the computer starts in Safe Mode, you would remove the device that was causing the stop error. You can access the Windows 2000 Recovery Console by starting the computer from the Windows 2000 CD-ROM or the Windows 2000 boot disks and then choosing the repair option in setup. You can also install the Windows 2000 Recovery Console by running Winnt32.exe /cmdcons, and then you can access the Recovery Console from the Windows 2000 startup menu. On a domain controller you have backed up recently, restart the domain controller in Directory Services Restore Mode. Using the Backup utility, restore the system state data. Next, using the Ntdsutil.exe utility, mark the deleted OU as authoritative. Restart the domain controller and replicate the changes to the remaining domain controllers. The two types of emergency repair are Manual and Fast. You should normally choose Fast emergency repair because it is the easiest and does not require any user interaction. The fast repair will attempt to repair registry problems. You should only choose Manual emergency repair if you are an experienced user. Manual repair does not allow you to attempt to repair the registry. Chapter 13Upgrading a Network to Windows 2000
Yes. You must first upgrade to Windows NT Server 3.51 or 4.0, and then upgrade to Windows 2000. No. You can install the Directory Service Client for Windows 95 or 98. The laptop would then be able to access Active Directory directory services. SRV (Service) location resource records and the dynamic update protocol for DNS. Upgrade the master domain to Windows 2000 to create the root domain. To facilitate system recovery in the event of a problem during the upgrade, you should synchronize a BDC with the PDC and keep this BDC offline until you are sure the network upgrade has completed successfully. In all domain upgrade cases, the first step is to take a fully synchronized BDC offline to facilitate system recovery in case of problems during the upgrade. Next, upgrade the PDCs in the resource domains, and tell the Active Directory Installation wizard to make a new child domain in an existing domain tree. In this case, make the resource domains child domains of the old master domains. Finally, upgrade the BDCs of the resource domains. Nothing. The local groups remain, and group membership remains unchanged. Check that you have at least 32 MB of RAM and enough hard disk space free to complete the upgrade. You should also run the Windows 2000 Compatibility Tool to check that all hardware and software currently installed is compatible with Windows 2000. Chapter 14Upgrading a Network to Windows 2000
Remote installation requires the following five resources: A Windows 2000 Server with RIS installed and configured A DNS server available on the network A DHCP server available on the network A Windows 2000 domain to provide Active Directory directory services Client computers that meet the Net PC specification or have a boot floppy to connect to the RIS server. Windows 2000 ships with the Windows 2000 Remote Boot Disk Generator (rbfg.exe), which is used to create boot disks. It is found on the RIS Server in the folder where the Windows 2000 Professional installation files are stored. The path is E:\RemoteInst\Admin\i386\rbfg.exe. The boot floppies created using Rbfg.exe only support the PCI-based network adapters listed in the Adapters List, Start Rbfg.exe and then click the Adapter List button to see the list of supported adpaters. You create distribution servers when you have mulitple installations to perform. Having more than one source of installation files, speeds up the installations. |
