Windows 2003 Interview Questions-2

How do you double-boot a Win 2003 server box? The Boot.ini file is set as read-only, system, and hidden to prevent unwanted editing. To change the Boot.ini timeout and default settings, use the System option in Control Panel from the Advanced tab and select Startup.

What do you do if earlier application doesn’t run on Windows Server 2003? When an application that ran on an earlier legacy version of Windows cannot be loaded during the setup function or if it later malfunctions, you must run the compatibility mode function. This is accomplished by right-clicking the application or setup program and selecting Properties –> Compatibility –> selecting the previously supported operating system.

If you uninstall Windows Server 2003, which operating systems can you revert to? Win ME, Win 98, 2000, XP. Note, however, that you cannot upgrade from ME and 98 to Windows Server 2003.

How do you get to Internet Firewall settings? Start –> Control Panel –> Network and Internet Connections –> Network Connections.

What are the Windows Server 2003 keyboard shortcuts? Winkey opens or closes the Start menu. Winkey + BREAK displays the System Properties dialog box. Winkey + TAB moves the focus to the next application in the taskbar. Winkey + SHIFT + TAB moves the focus to the previous application in the taskbar. Winkey + B moves the focus to the notification area. Winkey + D shows the desktop. Winkey + E opens Windows Explorer showing My Computer. Winkey + F opens the Search panel. Winkey + CTRL + F opens the Search panel with Search for Computers module selected. Winkey + F1 opens Help. Winkey + M minimizes all. Winkey + SHIFT+ M undoes minimization. Winkey + R opens Run dialog. Winkey + U opens the Utility Manager. Winkey + L locks the computer.

What is Active Directory? Active Directory is a network-based object store and service that locates and manages resources, and makes these resources available to authorized users and groups. An underlying principle of the Active Directory is that everything is considered an object—people, servers, workstations, printers, documents, and devices. Each object has certain attributes and its own security access control list (ACL).

Where are the Windows NT Primary Domain Controller (PDC) and its Backup Domain Controller (BDC) in Server 2003? The Active Directory replaces them. Now all domain controllers share a multimaster peer-to-peer read and write relationship that hosts copies of the Active Directory.

How long does it take for security changes to be replicated among the domain controllers? Security-related modifications are replicated within a site immediately. These changes include account and individual user lockout policies, changes to password policies, changes to computer account passwords,

and modifications to the Local Security Authority (LSA).

What’s new in Windows Server 2003 regarding the DNS management? When DC promotion occurs with an existing forest, the Active Directory Installation Wizard contacts an existing DC to update the directory and replicate from the DC the required portions of the directory. If the wizard fails to locate a DC, it performs debugging and reports what caused the failure and how to fix the problem. In order to be located on a network, every DC must register in DNS DC locator DNS records. The Active Directory Installation Wizard verifies a proper configuration of the DNS infrastructure. All DNS configuration debugging and reporting activity is done with the Active Directory Installation Wizard.

When should you create a forest? Organizations that operate on radically different bases may require separate trees with distinct namespaces. Unique trade or brand names often give rise to separate DNS identities. Organizations merge or are acquired and naming continuity is desired. Organizations form

partnerships and joint ventures. While access to common resources is desired, a separately defined tree can enforce more direct administrative and security restrictions.

How can you authenticate between forests? Four types of authentication are used across forests: (1) Kerberos and NTLM network logon for remote access to a server in another forest; (2) Kerberos and NTLM interactive logon for physical logon outside the user‘s home forest; (3) Kerberos delegation to N-tier application in another forest; and (4) user principal name (UPN) credentials.

What snap-in administrative tools are available for Active Directory? Active Directory Domains and Trusts Manager, Active Directory Sites and Services Manager, Active Directory Users and Group Manager, Active Directory Replication (optional, available from the Resource Kit), Active Directory Schema Manager (optional, available from adminpak)

What types of classes exist in Windows Server 2003 Active Directory?

 Structural class. The structural class is important to the system administrator in that it is the only type from which new Active Directory objects are created. Structural classes are developed from either the

modification of an existing structural type or the use of one or more abstract classes.

 Abstract class. Abstract classes are so named because they take the form of templates that actually create other templates (abstracts) and structural and auxiliary classes. Think of abstract classes as frameworks for the defining objects.

 Auxiliary class. The auxiliary class is a list of attributes. Rather than apply numerous attributes when creating a structural class, it provides a streamlined alternative by applying a combination of attributes with a single include action.

 88 class. The 88 class includes object classes defined prior to 1993, when the 1988 X.500 specification was adopted. This type does not use the structural, abstract, and auxiliary definitions, nor is it in common use for the development of objects in Windows Server 2003 environments.

How do you delete a lingering object? Windows Server 2003 provides a command called Repadmin that provides the ability to delete lingering objects in the Active Directory.

What is Global Catalog? The Global Catalog authenticates network user logons and fields inquiries about objects across a forest or tree. Every domain has at least one GC that is hosted on a domain controller. In Windows 2000, there was typically one GC on every site in order to prevent user logon failures

across the network.

How is user account security established in Windows Server 2003? When an account is created, it is given a unique access number known as a security identifier (SID). Every group to which the user belongs has an associated SID. The user and related group SIDs together form the user account‘s security token, which determines access levels to objects throughout the system and network. SIDs from the security token are mapped to the access control list (ACL) of any object the user attempts to access.

If I delete a user and then create a new account with the same username and password, would the SID and permissions stay the same? No. If you delete a user account and attempt to recreate it with the same user name and password, the SID will be different.

What do you do with secure sign-ons in an organization with many roaming users? Credential Management feature of Windows Server 2003 provides a consistent single sign-on experience for users. This can be useful for roaming users who move between computer systems. The Credential Management feature provides a secure store of user credentials that includes passwords and X.509 certificates.

Anything special you should do when adding a user that has a Mac? "Save password as encrypted clear text" must be selected on User Properties Account Tab Options, since the Macs only store their passwords that way.

What remote access options does Windows Server 2003 support? Dial-in, VPN, dial-in with callback.

Where are the documents and settings for the roaming profile stored? All the documents and environmental settings for the roaming user are stored locally on the system, and, when the user logs off, all changes to the locally stored profile are copied to the shared server folder. Therefore, the first time a roaming user logs on to a new system the logon process may take some time, depending on how large his profile folder is.

Where are the settings for all the users stored on a given machine? \Document and Settings\All Users

What languages can you use for log-on scripts? JavaScipt, VBScript, DOS batch files (.com, .bat, or even .exe)

Windows 2003 Interview Questions-1

What’s the difference between local, global and universal groups? Domain local groups assign access permissions to global domain groups for local domain resources. Global groups provide access to resources in other trusted domains. Universal groups grant access to resources in all trusted domains.

I am trying to create a new universal user group. Why can’t I? Universal groups are allowed only in native-mode Windows Server 2003 environments. Native mode requires that all domain controllers be promoted to Windows Server 2003 Active Directory.

What is LSDOU? It‘s group policy inheritance model, where the policies are applied to Local machines, Sites, Domains and Organizational Units.

Why doesn’t LSDOU work under Windows NT? If the NTConfig.pol file exist, it has the highest priority among the numerous policies.

Where are group policies stored? %SystemRoot%System32\GroupPolicy

What is GPT and GPC? Group policy template and group policy container.

Where is GPT stored? %SystemRoot%\SYSVOL\sysvol\domainname\Policies\GUID

You change the group policies, and now the computer and user settings are in conflict. Which one has the highest priority? The computer settings take priority.

You want to set up remote installation procedure, but do not want the user to gain access over it. What do you do? gponame–> User Configuration–> Windows Settings–> Remote Installation Services–> Choice Options is your friend.

What’s contained in administrative template conf.adm? Microsoft NetMeeting policies

How can you restrict running certain applications on a machine? Via group policy, security settings for the group, then Software Restriction Policies.

You need to automatically install an app, but MSI file is not available. What do you do? A .zap text file can be used to add applications using the Software Installer, rather than the Windows Installer.

What’s the difference between Software Installer and Windows Installer? The former has fewer privileges and will probably require user intervention. Plus, it uses .zap files.

What can be restricted on Windows Server 2003 that wasn’t there in previous products? Group Policy in Windows Server 2003 determines a users right to modify network and dial-up TCP/IP properties. Users may be selectively restricted from modifying their IP address and other network

configuration parameters.

How frequently is the client policy refreshed? 90 minutes give or take.

Where is secedit? It‘s now gpupdate.

You want to create a new group policy but do not wish to inherit.? Make sure you check Block inheritance among the options when creating the policy.

What is "tattooing" the Registry? The user can view and modify user preferences that are not stored in maintained portions of the Registry. If the group policy is removed or changed, the user preference will persist in the Registry.

How do you fight tattooing in NT/2000 installations? You can‘t.

How do you fight tattooing in 2003 installations? User Configuration - Administrative Templates - System - Group Policy - enable - Enforce Show Policies Only.

What does IntelliMirror do? It helps to reconcile desktop settings, applications, and stored files for users, particularly those who move between workstations or those who must periodically work offline.

What’s the major difference between FAT and NTFS on a local machine? FAT and FAT32 provide no security over locally logged-on users. Only native NTFS provides extensive permission control on both remote and local files.

How do FAT and NTFS differ in approach to user shares? They don‘t, both have support for sharing.

Explan the List Folder Contents permission on the folder in NTFS.?Same as Read & Execute, but not inherited by files within a folder. However, newly created subfolders will inherit this permission.

I have a file to which the user has access, but he has no folder permission to read it. Can he access it? It is possible for a user to navigate to a file for which he does not have folder permission. This involves simply knowing the path of the file object. Even if the user can‘t drill down the

file/folder tree using My Computer, he can still gain access to the file using the Universal Naming Convention (UNC). The best way to start would be to type the full path of a file into Run… window.

For a user in several groups, are Allow permissions restrictive or permissive? Permissive, if at least one group has Allow permission for the file/folder, user will have the same permission.

For a user in several groups, are Deny permissions restrictive or permissive? Restrictive, if at least one group has Deny permission for the file/folder, user will be denied access, regardless of other group permissions.

What hidden shares exist on Windows Server 2003 installation? Admin$, Drive$, IPC$, NETLOGON, print$ and SYSVOL.

What’s the difference between standalone and fault-tolerant DFS (Distributed File System) installations? The standalone server stores the Dfs directory tree structure or topology locally. Thus, if a shared folder is inaccessible or if the Dfs root server is down, users are left with no link to the

shared resources. A fault-tolerant root node stores the Dfs topology in the Active Directory, which is replicated to other domain controllers. Thus, redundant root nodes may include multiple connections to the same data residing in different shared folders.

We’re using the DFS fault-tolerant installation, but cannot access it from a Win98 box. Use the UNC path, not client, only 2000 and 2003 clients can access Server 2003 fault-tolerant shares.

Where exactly do fault-tolerant DFS shares store information in Active Directory? In Partition Knowledge Table, which is then replicated to other domain controllers.

Can you use Start->Search with DFS shares? Yes.

What problems can you have with DFS installed? Two users opening the redundant copies of the file at the same time, with no file-locking involved in DFS, changing the contents and then saving. Only one file will be propagated through DFS.

I run Microsoft Cluster Server and cannot install fault-tolerant DFS. Yeah, you can‘t. Install a standalone one.

Is Kerberos encryption symmetric or asymmetric? Symmetric.

How does Windows 2003 Server try to prevent a middle-man attack on encrypted line? Time stamp is attached to the initial client request, encrypted with the shared key.

What hashing algorithms are used in Windows 2003 Server? RSA Data Security‘s Message Digest 5 (MD5), produces a 128-bit hash, and the Secure Hash Algorithm 1 (SHA-1), produces a 160-bit hash.

What third-party certificate exchange protocols are used by Windows 2003 Server? Windows Server 2003 uses the industry standard PKCS-10 certificate request and PKCS-7 certificate response to exchange CA certificates with third-party certificate authorities.

What’s the number of permitted unsuccessful logons on Administrator account? Unlimited. Remember, though, that it‘s the Administrator account, not any account that‘s part of the Administrators group.

If hashing is one-way function and Windows Server uses hashing for storing passwords, how is it possible to attack the password lists, specifically the ones using NTLMv1? A cracker would launch a dictionary attack by hashing every imaginable term used for password and then compare the hashes.

What’s the difference between guest accounts in Server 2003 and other editions? More restrictive in Windows Server 2003.

How many passwords by default are remembered when you check "Enforce Password History Remembered"? User‘s last 6 passwords.
