Network connectiviry issue
When the client computer cannot contact the DHCP server for IP address configuration, Windows XP uses APIPA (Automatic Private IP Address) for IP configuration. This allows the client computer to communicate with other computers and printers on a single subnet. APIPA uses the private IP address range of 169.254.0.1 through 169.254.255.254 and a subnet mask of 255.255.0.0. 169.254.96.107 is thus an APIPA address that was assigned by Windows because the computer did not receive an IP configuration from a DHCP server. By running the Ipconfig /renew command we will force the computer to attempt to contact the DHCP server again so that it renew the client IP configuration.
Problem with network access to document
A user is attempting to open a Microsoft Word document Phonelist.doc by using Internet Explorer. However, when he types http://Server1/Files/Phonelist.doc into the address bar in Internet Explorer, he receives the following error message: “404: Page not found.”. You verify that Phonelist.doc exists in a shared folder named Files on Server1. You need to ensure that user can access Phonelist.doc by using Internet Explorer. What should you do?
The error message 404 indicates that the Web page cannot be located at the URL address specified by the user. This is because the user specified a Web server address, which is denoted by http:// in the URL. He should use file:// in the URL to specify a file server. The correct URL for opening the file with a Web browser in this scenario is file://server1/File/Phonelist.doc.
Problem with Remote Desktop Services
You need to establish a Remote Assistance connection with Michael’s computer. What should you do next? The right answer is to ask your firewall administrator to open the TCP/IP ports that are used by Remote Desktop Services.
The problem in this scenario is that the firewall is blocking the Remote Desktop Protocol port 3389. Remote Assistance uses the Remote Desktop Protocol port 3389 for outbound RDP traffic. This port is typically blocked on most firewalls, in which case we cannot connect to the Remote Desktop. We must configure the firewall to enable Remote Desktop Services program, which is Mstsc.exe, to make outbound TCP connections on port 3389.
The DNS problem in network
The network consists of a single Active Directory domain. The network includes Windows 2000 Advanced Server computers, and Windows 2000
Professional and Windows XP Professional client computers. Except for the domain controllers, all computers on the network use DHCP for their TCP/IP configuration. Users begin reporting that when they try to access resources on File Server, they receive the following error message: “Network path not found.”
The likely problem in this scenario is that when the file server was restarted, it received a new IP address. When a user connects to a server using a user-friendly name, DNS resolves the user-friendly name to an IP Address that is then used to connect to the server. This name-to-IP address resolution is then stored in cache on the user’s computer so that when they attempt to connect to the same server, they do not have to use DNS. The DNS cache on the users’ computers has the old IP address for the file server. Thus, when the client attempts to contact the file server it is using the wrong IP address that it has cached. The /flushdns switch of the Ipconfig command flushes the list of locally cached DNS names.
Configuration for strong company policies
If you should configure a computer so that user can dial in to the company network while out of the office. Company security policy states that dial-in users must use a smart card when they connect to the network, and that the users must use the strongest form of data encryption possible. Company security policy also states that client computers must disconnect if the routing and remote access server does not support both smart card authentication and the strongest possible authentication. You need to configure the dial-up connection properties on user’s computer to dial in to the company network. Your solution must ensure that company security policies are enforced. Then in this case you should select the Advanced (custom settings) security option. Then should Select the Maximum strength encryption item from the Data encryption list. And finally Select the Extensible Authentication Protocol (EAP) option, and select Smart Card or other
Certificate from the EAP list.
Remote connection to application
When an expert attempts to connect to a novice’s computer, the expert may receive the following error message: ” A Remote Assistance connection could not be established. You may want to check for network issues or determine if the invitation expired or was cancelled by the person who sent it.”
This problem can occur if the Internet Connection Firewall has been enabled after the Remote Assistance invitation was created. To resolve this problem, we should either create a new Remote Assistance invitation while ICF is enabled, and then send the new invitation to the expert; or we should disable the Internet Connection Firewall while the expert attempts to establish the Remote Assistance invitation; or restart the novice’s computer, and then have the expert establish the Remote Assistance session.
Configuring of the users’ applications
Users in the accounting department run an application that requires several hours to process financial and accounting data. Users in the accounting department report that when they run this application, the performance of other business applications becomes significantly slower. You need to allow the accounting application to run with the least amount of performance impact on the other business applications. You should configure all accounting application to have BelowNormal priority. To resolve the problem in this scenario we must lower the priority of the accounting application. The priority must be lowered from Normal to either Low or to BelowNormal. This will result in less system resources being allocated to the application and will leave more resources for other processes. This would thus improve the performance of the other applications while allowing accounting application to run.
Backup of user’s information
You are the desktop administrator for the Graphic Design Institute. You have just deployed new Windows XP Professional computers to all graphic designers. Each computer has a built-in tape drive for data backups. The graphic designers need to back up their own data to the tape drive. You add all graphic designers’ user accounts administrator members of the Backup Operators group on their computers. Then you instruct the graphic designers to create a full backup of all their data every Monday morning. The graphic designers need to back up all of their data once a week. They also need to back up all the changes since the last full backup. The graphic designers want to use a backup method that allows them to recover their data as quickly as possible. You should advice graphic designer to perform a normal backup every Monday. Create an Incremental backup for Tuesday, Wednesday, Thursday, and Friday. A Differential back up only backs up files and folders that are marked as having been altered since the last full backup but does not clear these markers. These markers are called archive bits. Thus, if we performed two differential backups on a file that has been altered since the last full back but not since the last differential backup, the file would be backed up on both occasions. This provides the quickest recovery method as we would have to restore only the most recent full backup and the most recent differential backup.
Hardware profiles configuration of notebook with IEEE 1394 PC card
You install Windows XP Professional on your portable computer. The computer is configured to use an IEEE 1394 PC card. You use the computer to download pictures from a digital camera while you are at the office. You attend a meeting every Monday. During the meeting you use a battery to supply power to your portable computer. Occasionally, the battery runs out of power during these meetings. You need to configure the computer to conserve battery power while you attend your weekly meeting without affecting your power options when you use the computer at your office. You should also Create an additional hardware profile, and disable the IEEE 1394 PC card for this profile. To ensure the optimal performance in different networking environments, we should create different hardware profiles that the users can choose from under different network environments. We do not require the IEEE 1394 PC card at the meeting therefore we should create a profile that has the IEEE 1394 PC card disabled to save the battery resources used to power this card. We can then choose this profile when he we are at the meeting.
