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:
1. System Monitor, and
2. Performance Logs and Alerts.
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:
1. Safe Mode
2. Safe Mode with Networking
3. Safe Mode with Command prompt
4. Enable Boot Logging
5. Enable VGA Mode
6. Last Known Good Configuration
7. Debugging Mode
8. Boot Normally
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:
1. Boot sector virus
2. 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:
1.
FAT: Also called FAT16, supported by all Microsoft
Operating Systems.
2.
FAT32: Also supported by Win 95 OSR2 and Win98
3.
NTFS: This is not supported by Win95/98
4.
CDFS (Compact Disk File System, used to access CDs)
5.
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.

create, manage, and delete simple volumes, spanned
volumes, mirrored volumes, striped, and stripe set
with parity volumes. Disk Administrator is NT 4 tool

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.
