61. To find the effective NTFS
permissions, you add up all the
permissions given to different
groups that a user is member of,
and remove all entries with
“Deny” permissions (if any). In
other words, if any user or
group is denied access to a file
or folder, it overrides any
“Allow” permissions.
62. In Windows 2000
Professional, the default
permissions for a subfolders or
files are inherited from the
parent folder. Compare this with
Windows NT 4 where, any
subfolder newly created will not
inherit any permission from the
parent folder. Only files
created will inherit permissions
from the folder.
63. Compression and encryption:
If you encrypt a folder on an
NTFS volume, all files and
subfolder created 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.
64. Windows 2000 provides two
versions of Registry Editor
1.
Regedt32.exe (32-bit) and
2.
Regedit.exe (16-bit).
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.
65. Disk Quotas:
1.
To support disk quotas, a
disk volume must be formatted
with the version of NTFS used in
Windows 2000. Volumes formatted
with the version of NTFS used in
Windows NT 4.0 are upgraded
automatically by Windows 2000
Setup.
2.
To administer quotas on a
volume, you must be a member of
the Administrators group on the
computer where the drive
resides.
3.
File compression does not
affect quota statistics. In
other words, if a user is
allowed 10MB of disk space, he
or she can store a total of 10MB
of files / folder irrespective
of whether the files / folders
are compressed or not.
4.
If a user ‘A’ takes
ownership of a file copied to an
NTFS volume by another user ‘B’,
the user A's action causes the
disk space occupied by the file
to be charged against the user
A's quota limit.
