Consider a TCP client and TCP server running on two different machines. After completing data transfer, the TCP client calls close to terminate the connection and a FIN segment is sent to the TCP server. Server-side TCP responds by sending an ACK, which is received by the client-side TCP. As per the TCP connection state diagram (RFC 793), in which state does the client-side TCP connection wait for the FIN from the server-side TCP?
You are the administrator of a SQL Server 2000 computer. The server contains a database named FinanceData that is used by a client/server application. Each employee has a SQL Server login that the application uses to access the server.Your company hires a new employee named Andrew. You create a SQL Server login named Andrew. You also create a database user named Andrew in the database and grant the database user full permissions in the database.Whenever Andrew runs the client/server application, he receives the following error message: "Invalid object name." Andrew also reports that he cannot access the database by using the application.You need to ensure that Andrew can use the application. Which Transact-SQL statement should you execute?
You are the administrator of the Windows 2000 Server network shown in the exhibit. Users in the Research group and the Executive group have permission to access the Internet through a Windows 2000 Server computer running Microsoft Proxy Server. These users must enter their proxy server user names and passwords to connect to the proxy server, to the Internet, and to your local intranet server. The users who do not access the Internet do not have user accounts on the proxy server and, therefore, cannot connect to the intranet server. You want all users to be able to connect to the intranet server without entering a separate user name and password. What should you do?
Your network contains 10 domain controllers, 10 member servers, and approximately 1,000 client computers. All the servers run Windows 2000 Server, and all the client computers run Windows 2000 Professional. Two of the domain controllers act as DNS servers. Users of client computers use file sharing to grant access to files stored locally. The network has 10 subnets and uses TCP/IP as the only network protocol. You want to configure the network so that all computers can resolve the addresses of all other computers by using DNS. Client computers must be able to register and resolve addresses if a server fails. How should you configure the DNS servers?
You are the administrator of a Microsoft Windows NT Server 4.0 computer. The server is the PDC in your domain and also runs SQL Server 2000. The server has four processors and 1 GB of RAM.Your network consists of 500 client computers that are running Microsoft Windows Millennium Edition. Users report that when they log on in the morning their computers respond slowly and occasionally return error messages.You use System Monitor to monitor processor performance and RAM utilization. You discover that the % Total Time and % User Time counters average 90 percent and the % Privileged Time counter averages 20 percent. The Available Mbytes counter averages 800 MB. You need to improve server performance for user logons. What should you do?
You install a Windows 2000 Server computer on your network. You place several shared folders on a 12-GB primary partition formatted by FAT32. During nine months of continuous operation, the number of users who access the server and their access frequency remains constant. The average size of the files on the server remains approximately constant. After the server runs continuous for nine months, users report that the server does not retrieve files from the shared folders as fast as when you first installed the server. What should you do to resolve the problem?

Consider the following statements regarding Peer-to-Peer computing environment: 1. In this system, clients and servers are not distinguished from one another. 2. All nodes distributed throughout the system (within) are considered Peers and each may act as either a client or a server. 3. Peer-to-Peer system assuredly offers certain advantages over the traditional client-server system. 4. Peer-to-Peer system is just a replica of the file-server system. Which of the above statements are correct?
Your network consists of a single Active Directory domain. All servers run Windows Server 2003 Service Pack 2 (SP2). All client computers run Windows XP Service Pack 3 (SP3). You install and configure Microsoft Windows Server Update Services (WSUS) 3.0 on a member server named Server1. You create a new Group Policy Object named GPO1 that enables automatic updating. You link GPO1 to the domain. You need to ensure that each client computer obtains software updates from Server1. What should you do?
You are the administrator of a Windows 2000 Server network that runs in mixed mode. You install a new Windows 2000 Server computer. You create and share a new HP LaserJet 4L printer. Your Windows 2000 Professional client computers can print to the new printer successfully. However, when users try to connect to the printer from Windows NT Workstation 4.0 client computers, they receive the dialog box shown in the exhibit. "The server on which the printer resides does not have a suitable HP LaserJet printer driver installed". You want the printer driver to be installed automatically on the Windows NT Workstation computers. What should you do?
