There are a number of errors one could find in a Windows Server 2003 DNS log. They are as follows: The DNS server could not create a Transmission Control Protocol. The DNS server could not open socket for address. The DNS server could not initialize the Remote Procedure Call (RPC) service. The DNS server could not bind the main datagram socket. The DNS Server service relies on Active Directory to store and retrieve information for Active Directory-integrated zones. And several active directory errors are possible.

Answer: B is incorrect. DNS Servers do not create FTP connections. Answer: A is incorrect. DNS Servers do not create SMTP connections.

The major advantage that a table-structured Web site has over a frame-structured Web site is that users can bookmark the pages of a table- structured Web site, whereas pages of a frame-structured Web site cannot be bookmarked or added to the Favorites folder. Non-frame Web sites also give better results with search engines. Better navigation: Web pages can be divided into multiple frames and each frame can display a separate Web page. It helps in providing better and consistent navigation. Easy maintenance: Fixed elements, such as a navigation link and company logo page, can be created once and used with all the other pages. Therefore, any change in these pages is required to be made only once.

The following are the drawbacks of the NTLM Web Authentication Scheme: NTLM Web authentication is not entirely safe because NTLM hashes (or challenge/response pairs) can be cracked with the help of brute force password guessing. The "cracking" program would repeatedly try all possible passwords, hashing each and comparing the result to the hash that the malicious user has obtained. When it discovers a match, the malicious user will know that the password that produced the hash is the user's password. This authentication technique works only with Microsoft Internet Explorer. Answer: A, C are incorrect. NTLM authentication does not send the user's password (or hashed representation of the password) across the network. Instead, NTLM authentication utilizes challenge/response mechanisms to ensure that the actual password never traverses the network. How does it work? When the authentication process begins, the client sends a login request to the telnet server. The server replies with a randomly generated 'token' to the client. The client hashes the currently logged-on user's cryptographically protected password with the challenge and sends the resulting "response" to the server. The server receives the challenge-hashed response and compares it in the following manner:

The server takes a copy of the original token. Now it hashes the token against the user's password hash from its own user account database. If the received response matches the expected response, the user is successfully authenticated to the host.
