22. VIRUS:

23. TCP/IP

24. Networking utilities:

25. Some of the important commands useful in trouble shooting TCP/IP networks are:

26. To see TCP/IP configuration on a Windows 95 / 98 computer, use WINIPCFG. It will display your IP address, subnet mask, default gateway, hardware MAC address.

To see TCP/IP configuration on an NT machine, use IPCONFIG. It will also display the IP configuration information on an NT machine. To get more details, use IPCONFIG/ALL.

27. DLL stands for Dynamic Link Library. DLL is a special form of application code loaded into memory by request. A DLL is not executable by itself. More than one application may use the functions offered by a DLL.

28. HTML stands for Hyper Text Markup Language. HTML is the language most widely used for writing Web pages.

29. You can't apply file level permissions on a FAT file system. Only NTFS allows file permissions. Remember that the NTFS file permissions are always in effect to all users and processes.

When you install Windows 2000 in the same folder as that of Windows 95/ Windows 98/ Windows NT, the operating system gets upgraded to Windows 2000.

TCP/IP protocol stack is installed by default when you install Windows 2000 on a computer.

You can use Regional Options to support additional languages on your computer. With the support of additional languages, you will be able to edit documents written in those languages. You can also set locale specific to any region using this Option.

The Windows 2000 Performance tool is composed of two parts:

With System Monitor, you can collect and view real-time data about memory, disk, processor, network, and other activity in chart (graph), histogram, or report form.

Through Performance Logs and Alerts you can configure logs to record performance data and set system alerts to notify you when a specified counter's value is above or below a defined threshold.

Event Viewer maintains logs about program, security, and system events. You can use Event Viewer to view and manage the event logs, gather information about hardware and software problems, and monitor Windows 2000 security events.

To open Event Viewer, click 'Start', point to 'Settings', and then click 'Control Panel'. Double-click 'Administrative Tools', and then double-click Event Viewer.

Encrypting File System (EFS) keeps your documents safe from intruders who might gain unauthorized physical access to your sensitive stored data by stealing your laptop or Zip disk, or by other means.

You need to ensure the following before the upgrade:

If you are creating a Striped volume on a new Windows 2000 machine, it can only be created on dynamic disks. However, if you are upgrading a Windows NT computer to Windows 2000, any existing stripe set will be supported.

For creating Stripe set with parity, we need at least 3 disk volumes.

Placing the paging file on different physical disks is optimal. This will improve faster access to the Paging file, and also distribute the load.

Microsoft Internet Explorer and Windows Explorer can be used for assigning Share and NTFS permissions on a Windows 2000 computer.

32. File names can be 255 characters long on a FAT, FAT32, and NTFS file systems.

33. Windows 2000 system monitoring:

Some of the important System Monitor counters are:

34. To insert a new file extension, you use Windows explorer, and select the application. Then, Tools -> Folder Option -> File Types. Configure the extension appropriately.

35. Windows 2000 disk volumes:

Windows 2000 Operating systems support 5 different volume types:

Note that Windows 2000 Professional doesn’t support Mirrored and RAID-5 volumes, where as other Windows 2000 Operating Systems (2000 Server, Advanced Server) support.

36. Fault tolerance boot disk is a floppy disk that enables you to boot a computer in the event that the first disk in a mirrored volume fails. If you mirror the installation folder in a Windows 2000 Server, you will not be able to boot because boot.ini points to the first volume. Therefore, you need to create a fault tolerance boot disk that contain an appropriately edited Boot.ini file, that points to the mirrored volume.

37. By default, you can start recovery console (in Windows 2000) using,

Also, you can have “Recovery Console” as a start up option by typing \i386\winnt32.exe /cmdcons at the command prompt, after switching to the CD ROM drive letter.

38. Windows 2000 provides two versions of Registry Editor

Regedt32.exe is automatically installed in the systemroot\system32 folder, while Regedit.exe is automatically installed in the systemroot folder. Regedit.exe is primarily used for its search capabilities as it doesn’t support all functions and data types.

39. On a Windows 2000 computer, the default spool folder is located at: Systemroot\System32\spool\printers. For example, if the OS is residing on C drive, the default location will be: “C:\\WINNT\System32\spool\printers”.

You can access this location through:

Start -> Printers -> File -> Server Properties -> Advanced tab. Type in the new spool location over the default location.
