41. By default, Windows 2000 stores a user's profile in the C:\Documents and Settings\ user_name folder on the computer the user logs on. When a new user logs on, his initial user profile is an exact copy of either the local or domain-wide :default user: profile folder. The local default user profile folder is located in %root%\Documents and Settings. If you have installed Windows 2000 in C drive, it is C:\Documents and Settings.
42. 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.
43. Pressing F8 during boot process in Windows 2000 desk top bring up the following options:
- Safe Mode loads only the drivers necessary to get the desk top up and running. The drivers loaded with Safe Mode include mouse, monitor, keyboard, hard drive, and standard video driver.
- Safe Mode with Networking is same as Safe Mode with networking enabled.
- Safe Mode with Command Prompt option loads the command prompt instead of Windows 2000 graphical interface.
- Enable VGA Mode option loads a standard VGA driver. This option is good if you have any problem with newly installed video driver.
- Last Known Good Configuration enables the desk top to load the configuration that was stored when it was booted successfully last time. This option can't take care of any hardware related problems.
- The Debugging Mode option runs the Kernel Debugger, if that utility is installed.
- The Boot Normally is same as not pressing the F8 key. The Windows boots normally
44. You can access Task Manager by pressing <Alt> <Ctrl> <Del>. The applications tab lists all the applications that are currently running on the computer. The current status of the application is also displayed as either :Running: or :not responding: or :stopped:.
45. Blue screen messages are also called STOP messages. You will not be allowed to proceed, when a blue screen message appears. The most likely cause of blue screen messages are:
- Boot sector virus
- IRQ/ IO address conflicts.
You can check for any boot sector virus, and also for any conflicting IRQ / IO addresses.
46. You can configure support for multiple displays on your Windows 2000 computer. This is done through the use of Control Panel -> Display -> Settings. A Windows 2000 computer can support up to ten display monitors at the same time. Use additional video cards as required.
47. On a Windows 2000 computer, disk quotas can be used on NTFS volumes. Windows Explorer can be used to configure and monitor disk quotas.
48. On a Windows computer, you can use the View tab in Folder Options applet in the Control Panel to show / hide files and folders that have :Hidden: attribute set. You can also use Windows Explorer -> Tools -> Folder Options -> View tab.
49. If you want to install Windows 2000 on the same partition as that of Windows 98, install 2000 Professional either on the FAT file systems or on the FAT32 for dual boot. Windows 98 supports FAT (FAT16) and FAT32. It doesn't support NTFS file system.
50. The various file systems supported by Windows 2000 are:
- FAT: Also called FAT16, supported by all Microsoft Operating Systems.
- FAT32: Also supported by Win 95 OSR2 and Win98
- NTFS: This is not supported by Win95/98
- CDFS (Compact Disk File System, used to access CDs)
- UDF (Universal Disk Format, used to access DVDs)
51. If you want to have dual boot between Windows NT 4 and Windows 2000, ensure that Service Pack 4 is installed on Windows NT 4. This is required since Windows 2000 upgrades the NTFS to NTFS 5. NT4 requires Service Pack 4 to read and write to NTFS 5.
52. If you encrypt a folder on an NTFS volume, all files and subfolders created in the encrypted folder are automatically encrypted. Therefore, it is recommended that you use encryption at the parent folder level.
Also note that you can't encrypt a file or folder that is compressed. If you want to encrypt a file or folder that is compressed, you need to first decompress the file or folder and then encrypt. Only NTFS volumes support file or folder encryption.
53. You don't need to have a network card installed for successful installation of Windows 2000 Professional. You can use loop back adapter for this purpose and proceed with the installation. Network card can be installed at a later time, when required.
54. In Windows 2000 computer, Disk Management is used to create, manage, and delete simple volumes, spanned volumes, mirrored volumes, striped, and stripe set with parity volumes. Disk Administrator is NT 4 tool and is not available in Windows 2000.
55. Only Windows NT Server 4 and Windows NT Server 3.51 can be upgraded to Windows 2000 Server. Windows NT Workstation 4.0 or Windows 95/98 cann't upgraded to 2000 Server.
56. You can use System Monitor as well as Task Manager to monitor Processor and Memory usage on your Windows 2000 computer.
