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.

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?

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

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 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.
