| 1 | Dr. Watson for Windows NT is a kernel debugger. | F | 600.1 100% |
| "Dr. Watson for Windows NT is an application error debugger. It detects application errors, diagnoses the error, and logs the diagnostic information." | |||

100% |
| "In order to properly use Kernel Debugger to view the kernel mode drivers and services loaded during a
Windows NT computer initialization, the following requirements must be met:
"· Two Windows NT-based computers: one running Kernel Debugger (host computer), and the other to be debugged (target computer). Both computers should be running the same version of Windows NT. "· A connectivity mechanism between the two computers. For example, they can be connected by a null modem cable or modem connection for remote dial-in." | |||
| 3 | The symbol file for the target computer must be available on the host computer before kernel debugging can be successful. | T | 590.3
100% |
| "Configuring Kernel Debugger on the host computer requires the following steps:
"· Copy the Kernel Debugger files and Windows NT symbols from the Windows NT compact disc to the host computer (the computer that will be running the Kernel Debugger software). . . . "A common problem in configuring the Kernel Debugger occurs if the wrong symbol files are used. A symbol gives the debugger the information it needs to decode errors. To avoid possible errors and misinterpretation of data, use symbols from the same version of Windows NT in which the computer was booted. Also use the correct symbols for the target computer.. . .. Copy the appropriate symbol files to the host computer to enable proper debugging of the target computer. " | |||

How does increasing the client's local cache optimize Intranet Browsing? | The more cache available for quick downloading of web pages, the less web pages are forced deleted from cache to make room for newly arrived web pages, and thus needing to be retrieved again from slower method of reloading it from over the network.. | 419.3.3 |
| Optimizing Intranet Browsing Traffic
The most effective optimization of intranet browsing traffic is during the creation of Web pages because the majority of Web traffic is caused by the size of the files being copied across the network. Because intranet browsing can generate very significant amounts of network traffic, anything that can be done to reduce the traffic generated can be beneficial in the overall scheme of network usage. . . . Increase the client's local cache. When browsing an intranet, pages are downloaded to the client, and placed in a directory called the cache. When the designated amount of disk space for the cache is used, and more files are required, the cache must be emptied (deleted). Thus, a previously loaded file must be copied over the network again, instead of loading it from the local hard disk cache. | |||

| UDP Port 137 (NetBIOS Name Service Broadcasts)
Not all WANs will have problems browsing. Some routers can be configured to forward specific types of broadcasts and filter out others. All NetBIOS over TCP/IP (NetBT) broadcasts are sent to the UDP port 137, which is defined as the NetBT Name Service. This usage is defined by Request for Comment (RFC) 1001 and 1002. Routers normally filter out these frames because they are sent to the hardware and subnet broadcast addresses. However, some routers allow all frames sent to this particular UDP port which is used only by NetBT to be forwarded. As a result, the browser looks as if it is on one, big, network segment. All domains and computers within the network segments are seen by all computers, including Windows for Workgroups computers. p. 66.5,6 B. Why Use WINS? 1. Drawbacks of Existing Name Resolution Methods (a) Broadcasts 1) Using broadcasts to resolve NetBIOS names to IP addresses causes significant traffic on the network. 2) The larger the network, the more broadcasts. 3) If only broadcasts are used to resolve NetBIOS Names to IP addresses, routers must forward broadcasts, thus further increasing network traffic Outline on CD Chapter 4 Lesson 2, page 75 | |||

| host name The name of a device on a network. For a device on a Windows or Windows NT network, this
can be the same as the computer name, but it may not be. The host name must be in the host table or be
known by a DNS server for that host to be found by another computer attempting to communicate with it.
See also Domain Name System (DNS); host table.
HOSTS file A local text file in the same format as the 4.3 Berkeley Software Distribution (BSD) UNIX \etc\hosts file. This file maps host names to IP addresses. In Windows NT, this file is stored in the \systemroot\System32\Drivers\Etc directory. See also IP address. host table The HOSTS and LMHOSTS files, which contain mappings of known IP addresses mapped to host names. LMHOSTS file A local text file that maps IP addresses to the computer names of Windows NT networking computers outside the local subnet. In Windows NT, this file is stored in the \systemroot \System32\Drivers\Etc directory. See also IP address; subnet. A-type resource record A line (record) in a computer's Domain Name System database that maps a computer's domain name (host name) to an IP address in a DNS zone. broadcast name resolution A mechanism defined in RFC 1001/1002 that uses broadcasts to resolve names to IP addresses through a process of registration, resolution, and name release. See also broadcast datagram; IP address. caching In DNS name resolution, caching refers to a local cache where information about the DNS domain name space is kept. Whenever a resolver request arrives, the local name server checks both its static information and the cache for the name to IP address mapping. See also Domain Name System (DNS); IP address; mapping. Domain Name System (DNS) Sometimes referred to as the BIND service in BSD UNIX, DNS offers a static, hierarchical name service for TCP/IP hosts. The network administrator configures the DNS with a list of host names and IP addresses, allowing users of workstations configured to query the DNS to specify remote systems by host names rather than IP addresses. For example, a workstation configured to use DNS name resolution could use the command ping remotehost rather than ping 172.16.16.235 if the mapping for the system named remotehost was contained in the DNS database. DNS domains should not be confused with Windows NT networking domains. See also IP address; ping. IP address Used to identify a node on a network and to specify routing information. Each node on the network must be assigned a unique IP address, which is made up of the network ID, plus a unique host ID assigned by the network administrator. This address is typically represented in dotted-decimal notation, with the decimal value of each octet separated by a period (for example, 138.57.7.27). In Windows NT, the IP address can be configured statically on the client or configured dynamically through DHCP. See also Dynamic Host Configuration Protocol (DHCP); node; octet. | |||
