What is Global Catalog Server?

A global catalog server is a domain controller it is a master searchable database that contains information about every object in every domain in a forest. The global catalog contains a complete replica of all objects in Active Directory for its host domain, and contains a partial replica of all objects in Active Directory for every other domain in the forest.

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.

What remote access options does Windows Server 2003 support?

Dial-in, VPN, dial-in with callback.

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.

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.

What can be restricted on Windows Server 2003 that wasn't there in previous products?

In Partition Knowledge Table, which is then replicated to other domain controllers.

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.

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.

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. Hashing is taking a value (a persons name, date of birth or anything) called a KEY and subjecting it to an algorithm. The value produced is normally numeric. The key thing about a hash is that without the algorithm it is impossible to determine the original value. For example my name is Ken. If I have an algorithm that changes my name to a value of say 56 it would be impossible to know from looking at 56 that the original value was Ken.

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.

Is Kerberos encryption symmetric or asymmetric?

Symmetric. Symmetric encryption is where the same key is used to encrypt and decrypt the message. This differs from asymmetric (or public-key) encryption, which uses one key to encrypt a message and another to decrypt the message.

What is presentation layer responsible for in the OSI model?

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.

What is "tattooing" the Registry?

The registry contains 2 zones. One zone is specially designated zone, whereby any registry changes made can be reversed when the policy is removed and hence prevent tattooing. These zones are under the following registry keys: HKEY_LOCAL_MACHINE\Software\Policies HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies HKEY_CURRENT_USER\Software\Policies HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies Any registry changes made (whether by GPO or any other method) that are not under these zones will result in tattoos. Specifically a tattoo is a change that persists even after the keys responsible for the change have been removed. Tattoos are best removed by using a change that has the opposite effect of the change that needs to be removed

We've installed a new Windows-based DHCP server, however, the users do not seem to be getting DHCP leases off of it?

The server must be authorized first with the Active Directory.

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.

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.

How do you double-boot a Win 2003 server box?

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.

What do you do if earlier application doesn't run on Windows Server 2003?
