6. Name the AD NCs and replication issues for each NC

Windows admin interview questions (includes Vista)

There are three predefined Naming Contexts (NC)
1. Domain Naming Context - One per domain. The domain naming context stores users, computers, groups, and other objects for that domain. All domain controllers that are joined to the domain share a full writeable copy of the domain directory partition. Additionally, all domain controllers in the forest that host the global catalog also host a partial read-only copy of every other domain naming context in the forest.



2. Configuration Naming Context - One per forest. It stores forest-wide configuration data that is required for the proper functioning of Active Directory as a directory service. Information that Active Directory uses to construct the directory tree hierarchy is also stored in the configuration directory partition, as is network-wide, service-specific information that applications use to connect to instances of services in the forest. Every domain controller has one fully writeable copy of the configuration directory partition.
3. Schema Naming Context - One per forest. The schema naming context contains the definitions of all objects that can be instantiated in Active Directory. It also stores the definitions of all attributes that can be a part of objects in Active Directory. Every domain controller has one fully writeable copy of the schema directory partition, although schema updates are allowed only on the domain controller that is the schema operations master.
You can also define your own naming context in Windows 2003 and later -- called Application Partitions. Replication issues are not specific to a naming context.

5.What is the SYSVOL folder?

Windows admin interview questions (includes Vista)

System Volume (SYSVOL) is a shared directory that stores the server copy of the domain public files (Policies and scripts) that must be shared for common access and replication throughout a domain. It must be located in NTFS volume (because junctions are used within the SYSVOL folder structure)

4.Where is the AD database held? What other folders are related to AD?

Windows admin interview questions (includes Vista)

The Active Directory Database is Stored in %SYSTEM ROOT%\NDTS folder. Main database file for active directory is ntds.dit. Along with this file there are other files also present in this folder. These files are created when you run dcpromo. These are the main files controlling the AD structure
 ntds.dit: This is the main database file for active directory.
 edb.log: Transaction performed to ad stored in this file.
 res1.log: Used as reserve space in the case when drive had low space.
 res2.log: Same as res1.log.
 edb.chk: This file records the transactions committed to ad database.



When a change is made to the Win2K database, triggering a write operation, Win2K records the transaction in the log file (edb.log). Once written to the log file, the change is then written to the AD database. System performance determines how fast the system writes the data to the AD database from the log file. Any time the system is shut down; all transactions are saved to the database.
During the installation of AD, Windows creates two files: res1.log and res2.log. The initial size of each is 10MB. These files are used to ensure that changes can be written to disk should the system run out of free disk space. The checkpoint file (edb.chk) records transactions committed to the AD database (ntds.dit). During shutdown, a "shutdown" statement is written to the edb.chk file. Then, during a reboot, AD determines that all transactions in the edb.log file have been committed to the AD database. If, for some reason, the edb.chk file doesn't exist on reboot or the shutdown statement isn't present, AD will use the edb.log file to update the AD database.
The last file in our list of files to know is the AD database itself, ntds.dit. By default, the file is located in\NTDS, along with the other files we've discussed

3. Can you connect Active Directory to other 3rd-party Directory Services? Name a few options.

Windows admin interview questions (includes Vista)

Active Directory is a LDAP compatible directory service and supported by various third party applications like Novell DirXML, and Atlassian Crowd.
Microsoft Identity Integration Server (MIIS) is one of the options you can use to act as an intermediary between two directories (including directories used by SAP, Domino, etc).



MIIS manages information by retrieving identity information from the connected data sources and storing the information in the connector space as connector space objects or CSEntry objects. The CSEntry objects are then mapped to entries in the metaverse called metaverse objects or MVEntry objects. This architecture allows data from dissimilar connected data sources to be mapped to the same MVEntry object. All back-end data is stored in Microsoft SQL Server.
Versions
 Zoomit Via (pre 1999)
 Microsoft Metadirectory Server [MMS] (1999–2003)
 Microsoft Identity Integration Server 2003 Enterprise Edition [MIIS] (2003-2009)
 Microsoft Identity Integration Server 2003 Feature Pack [IIFP] (2003-2009)
 Microsoft Identity Lifecycle Manager Server 2007 ILM (2007-2010)
 Microsoft Forefront Identity Manager 2010 FIM [CR0] (Current)

Supported Data Sources
MIIS 2003, Enterprise Edition, includes support for a wide variety of identity repositories including the following.
 Network operating systems and directory services: Microsoft Windows NT, Active Directory, Active Directory Application Mode, IBM Directory Server, Novell eDirectory, Resource Access Control Facility (RACF), SunONE/iPlanet Directory, X.500 systems and other network directory products
 E-mail: Lotus Notes and IBM Lotus Domino, Microsoft Exchange 5.5, 2000, 2003, 2007
 Application: PeopleSoft, SAP AG products, ERP1, telephone switches PBX, XML- and Directory Service Markup Language DSML-based systems
 Database: Microsoft SQL Server, Oracle RDBMS, IBM Informix, dBase, IBM DB2
 File-based: DSMLv2, LDIF, Comma-separated values CSV, delimited, fixed width, attribute value pairs

Yes. Microsoft Identity Integration Server (MIIS) is used to connect Active Directory to other 3rd-party Directory Services (including directories used by SAP, Domino, etc).

Yes We can Connect, by using dirxml and LDAP

2. What is LDAP?
LDAP, Lightweight Directory Access Protocol, is an Internet protocol that email and other programs use to look up information from a server.
Every email program has a personal address book, but how do you look up an address for someone who's never sent you email? How can an organization keep one centralized up-to-date phone book that everybody has access to?
That question led software companies such as Microsoft, IBM, Lotus, and Netscape to support a standard called LDAP. "LDAP-aware" client programs can ask LDAP servers to look up entries in a wide variety of ways. LDAP servers index all the data in their entries, and "filters" may be used to select just the person or group you want, and return just the information you want. For example, here's an LDAP search translated into plain English: "Search for all people located in Chicago whose name contains "Fred" that have an email address. Please return their full name, email, title, and description."



LDAP is not limited to contact information, or even information about people. LDAP is used to look up encryption certificates, pointers to printers and other services on a network, and provide "single signon" where one password for a user is shared between many services. LDAP is appropriate for any kind of directory-like information, where fast lookups and less-frequent updates are the norm.
As a protocol, LDAP does not define how programs work on either the client or server side. It defines the "language" used for client programs to talk to servers (and servers to servers, too). On the client side, a client may be an email program, a printer browser, or an address book. The server may speak only LDAP, or have other methods of sending and receiving data—LDAP may just be an add-on method.
If you have an email program (as opposed to web-based email), it probably supports LDAP. Most LDAP clients can only read from a server. Search abilities of clients (as seen in email programs) vary widely. A few can write or update information, but LDAP does not include security or encryption, so updates usually requre additional protection such as an encrypted SSL connection to the LDAP server.
LDAP also defines: Permissions, set by the administrator to allow only certain people to access the LDAP database, and optionally keep certain data private. Schema: a way to describe the format and attributes of data in the server. For example: a schema entered in an LDAP server might define a "groovyPerson" entry type, which has attributes of "instantMessageAddress", and "coffeeRoastPreference". The normal attributes of name, email address, etc., would be inherited from one of the standard schemas, which are rooted in X.500 (see below).
LDAP was designed at the University of Michigan to adapt a complex enterprise directory system (called X.500) to the modern Internet. X.500 is too complex to support on desktops and over the Internet, so LDAP was created to provide this service "for the rest of us."
LDAP servers exist at three levels: There are big public servers, large organizational servers at universities and corporations, and smaller LDAP servers for workgroups. Most public servers from around year 2000 have disappeared, although directory.verisign.com exists for looking up X.509 certificates. The idea of publicly listing your email address for the world to see, of course, has been crushed by spam.
While LDAP didn't bring us the worldwide email address book, it continues to be a popular standard for communicating record-based, directory-like data between programs.

1. What is Active Directory?
An active directory is a directory structure used on Microsoft Windows based computers and servers to store information and data about networks and domains.



A central component of the Windows platform, Active Directory directory service provides the means to manage the identities and relationships that make up network environments. Windows Server 2003 makes Active Directory simpler to manage, easing migration and deployment.

Backing Up the Registry

There are many backup programs for the registry but if the computer goes down and you can't fire off Win95 because of the registry problem.
Backup to a directory the following files:

• SYSTEM.DATA
• SYSTEM.DA0 (Yes seem to be the same size)
• USER.DAT
• USER.DA0 (Same size likely)
• WIN.INI
• CONTROL.INI
• SYSTEM.INI

These files can be copied to the windows directory from Win95 or DOS to help correct problems.

My Computer Won't Shut Down Itself After Installing XP

There are a number of users who are noticing that their PC will no longer automatically power down/shut off without pressing the power off button on the computers unlike in Windows Me/95/2000. There could be a number of reasons for this - but the main one seems to be that ACPI is not enabled on the computer or in Windows XP. Here is how to try that out:

1. Click - Start - Control Panel - Performance and Maintenance - Power Options Tab
2. Then click APM - Enable Advanced Power Management Support

How To Enable Hibernation

Under Windows 98, Me, or 2000 there was an option in the shutdown dialog box to enter the computer into hibernation (where all the content of the RAM is copied to the hard disk). The shutdown dialog box of Windows XP doesn't offer any longer the hibernation button. Some users may get confused about how to enable the hibernation mode. If this mode is supported by your motherboard (ACPI) you have to do the following:

1. Click Start and Shut Down,
2. Point the standby button and maintain the shift key pushed,
3. A new hibernation button appears: click it while still holding the shift key: voila your PC will hibernate.

Restricting Logon Access

If you work in a multiuser computing environment, and you have full (administrator level) access to your computer, you might want to restrict unauthorized access to your "sensitive" files under Windows 95/98.
One way is to disable the Cancel button in the Logon dialog box.
Just run Regedit and go to:

HKEY_LOCAL_MACHINE/Network/Logon
Create the "Logon" subkey if it is not present on your machine: highlight the Network key -> right-click in the left hand Regedit pane -> select New -> Key -> name it "Logon" (no quotes) -> press Enter. Then add/modify a DWORD value and call it "MustBeValidated" (don't type the quotes). Double-click it, check the Decimal box and type 1 for value.
Now click the Start button -> Shut Down (Log off UserName) -> Log on as a different user, and you'll notice that the Logon Cancel button has been disabled.

Search For Hidden Or System Files In Windows XP

The Search companion in Windows XP searches for hidden and system files differently than in earlier versions of Windows. This guide describes how to search for hidden or system files in Windows XP.
Search for Hidden or System Files By default, the Search companion does not search for hidden or system files. Because of this, you may be unable to find files, even though they exist on the drive.
To search for hidden or system files in Windows XP:
Click Start, click Search, click All files and folders, and then click More advanced options.

Click to select the Search system folders and Search hidden files and folders check boxes.
NOTE: You do not need to configure your computer to show hidden files in the Folder Options dialog box in Windows Explorer to find files with either the hidden or system attributes, but you need to configure your computer not to hide protected operating system files to find files with both the hidden and system attributes. Search Companion shares the Hide protected operating system files option (which hides files with both the system and hidden attributes) with the Folder Options dialog box Windows Explorer.

Add Open With to all files

You can add "Open With..." to the Right click context menu of all files.This is great for when you have several programs you want to open the same file types with. I use three different text editors so I added it to the ".txt" key.

1. Open RegEdit
2. Go to HKEY_CLASSES_ROOT\*\Shell
3. Add a new Key named "OpenWith" by right clicking the "Shell" Key and selecting new
4. Set the (Default) to "Op&en With..."
5. Add a new Key named "Command" by right clicking the "OpenWith" Key and selecting new
6. Set the (Default) to "C:\Windows\rundll32.exe shell32.dll,OpenAs_RunDLL %1", C:\ being your Windows drive. You must enter the "OpenAs_RunDLL %1" exactly this way.

Turn off Welcome screen

Open User Accounts in Control Panel.
Click Change the way users log on or off

XP Computer management console

To quickly access the computer management console, where you can see event logs (to see what's causing a problem, for example), right-click My Computer and choose Manage.
Then, select the Event viewer and double-click highlighted events in the Applications or System areas to view detailed explanations of what went wrong.

Automatic Screen Refresh

When you make changes to your hard drive and use Explorer, the changes are not usually displayed until you press the F5 key
To make the updates automatic:

1. Start Regedit
2. Go to HKEY_LOCAL_MACHINE / System / CurrentControlSet / Control / UpdateMode
3. Edit the DWORD value to be between 1 and 7
4. Restart Windows

Deleting Registry Keys from the Command Line

With the OEM Version of Windows95, a new switch, /D, is added to Regedit.
This enables you to delete items from Registry.
The syntax is: REGEDIT /L:system.dat_location /R:user.dat_location /D Reg_Key
where Reg_Key is the key you want to delete
There are two requirements:
1. That you have to boot to the same OEM version of Windows95 as the REGEDIT.EXE file.
2. You cannot be in Win95 at the time you use this switch.

Creating a Default File Opener

If you have a un-registered file type and want to view it with Explorer's Right-click
you can add your program to the right-click options by:

1. Starting Regedit
2. Go to HKEY_CLASS_ROOT / Unknown
3. Highlight the Shell Folder below it
4. Right click on Shell and create a New Key
5. Name it anything you want (For example NOTEPAD)
6. Create a New Key under that named command
7. Highlight the Command key
8. Double click on the Default value in the right hand panel
9. In Value Data, enter the path and filename of the program you want to use to open the file type
10. For example: C:\WINDOWS\NOTEPAD.EXE %1
11. Click on OK

In this example, when you right click on a file in Explorer, NOTEPAD will show up as an option.

Creating a Network Logon Banner

If you want to create a Network Logon Banner:

1. Start Regedit
2. Go To HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Winlogon
3. Create a new String called LegalNoticeCaption
4. Enter the text for your banner

Changing the Location of Windows95's Installation Files

If you need to change the drive and or path where Windows95 will look for it's installation files:

1. Start Regedit
2. Go to HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Setup \ SourcePath
3. Change the location from there
