Your network uses TCP/IP as the only network protocol. Devices on the network are configured to use IP address from the private 10.0.0.0 range. All the client computers on the network runs Windows 2000 Professional. The network includes Windows 2000 Server computers and UNIX servers. User's print jobs are sent to shared printers on a Windows 2000 Server computer named PrintServ that directs the print jobs to print devices attached directly to the network. You have a high-capacity print device that is attached to one of the UNIX servers. The UNIX computer uses the LPR printing protocol, and it's IP address is 10.1.1.99. The name of the printer queue is GIANT. You want users to be able to connect to this printer from their computers. What should you do?
You are the administrator of a Windows 2000 Server computer. The server contains one network adapter and is a file and print server for critical company resources. You install a second network adpater in the server and connect it to the same network subnet as the first adapter. You want to ensure that the first adapter is used for all network traffic and the second adapter is used only if the first adapter fails or is disconnected from the network.

Some users report that when they connect to the server they receive the following message |" IPX SPX compatible computer deported error 733" The EPP control network protocol for the network is not available. If the users allow the connection to continue they are able to connect to the services that use TCP/IP. You want to prevent this message from being displayed. What should you do?
You are installing a network interface card on a computer with the following configuration: a 5867133 CPU, 16MB or RAM, a 800-MB IDE hard disk, a parallel port configured as LPT1, and a serial port configured as COM1, which is currently used by a mouse. In addition to the IDE host adapter and the video card, the following devices have been installed on the computer's expansion bus: a modem on COM2, a SCSI host adapter for a CD-ROM drive, and a sound card. The SCSI hose adapter is using IRQ 5, and the sound card is using IRQ 11. The network interface card that you are installing supports the following choices for IRQ: 2, 3, 4, 5, 9,10 and 11. Which IRQ(s) could you use for the network interface card without creating an IRQ conflict with another device?
