This is the moving target Bill Gates set for Microsoft, for a while
we thought NT was going to upgrade to NT5, and Windows98 to Windows2000.
Then the new versions were renamed Windows2000, and WindowsME. He has been
pushing to merge the two streams, but they haven't been quite able to do
that. They are converging though.

Windows NT is being replaced by Windows 2000 not Windows XP.
Windows XP is replacing Windows 98. What you learn regarding NT is still
relevant for 2000 as it built on the same technology.

Thanks Eric.
This is the kind of information I would have liked to see in the
Mark Minasi
Mastering Windows NT book by Sybex, for example. We know where the
dialog
boxes and the buttons are, why hasn't anyone published info on how
to
configure NT properly.
Armed with that info, someone could then publish a book on how to
configure
Oracle to run properly on NT, in detail. (I looked at the Oracle on
NT book
from Prentice Hall already).
Funny that I find out only after the next MS OS is out, and they are
talking
about Windows XP now. The info is way behind the OS releases, I
would have
been happy to learn these things when NT was current, instead of
while it is
on its way out as an OS version.

---excerpts---
Windows NT Does Not Boot with Highly Fragmented MFT
...
SYMPTOMS
The Windows NT Start menu does not respond when you start
your
x86-based computer. A blinking cursor may appear in the
upper-left
corner of the screen, or an error message may be displayed.
This
issue only affects computers whose system partition (the
partition
containing NTLDR and Boot.ini) is formatted with the Windows
NT File
System (NTFS) file system.
CAUSE
This issue occurs because the low-level bootstrap code
contained in
the first few sectors of an NTFS volume can not cope with a
situation
where the volume's master file table (MFT) is highly fragmented.
The role of the bootstrap code is to locate and load the
NTLDR file
into memory. To perform this function, the bootstrap code
must
understand NTFS data structures well enough to locate NTLDR
on the
disk. This task involves reading the volume's MFT in order
to obtain
the root directory, which in turn contains information
necessary to
locate the entry in MFT for the NTLDR file itself.
The initial bootstrap code is very small and simple and runs
in the
processor's "real mode". Therefore, it cannot address large
amounts
of memory. When MFT is highly fragmented, the Windows NT 4.0
bootstrap code may run out of memory to store all the
necessary
records that describe MFT. This causes the system to stop
responding
(hang) and thus, the boot process does not proceed.
RESOLUTION
Windows NT Server or Workstation 4.0
To resolve this problem, obtain the latest service pack for
Windows
NT 4.0 or the individual software update.
...
WORKAROUND
To work around this issue, a discussion of MFT
fragmentation,
together with one method of preventing excessive MFT
fragmentation,
is presented in the following Microsoft Knowledge Base article:
Q174619 How NTFS Reserves Space for its Master File Table (MFT)
(
http://support.microsoft.com/support/kb/articles/Q174/6/19.ASP
<http://support.microsoft.com/support/kb/articles/Q174/6/19.ASP> )
After the system drive is sufficiently fragmented such that
the
system cannot start directly from the hard disk drive, it is
still
possible to start through a Windows NT startup floppy disk.
This is
possible because the floppy disk contains its own copy of
NTLDR. For
additional information, click the article number below to
view the
article in the Microsoft Knowledge Base:
Q119467 Creating a Boot Disk for an NTFS or FAT
Partition
(
http://support.microsoft.com/support/kb/articles/Q119/4/67.ASP
<http://support.microsoft.com/support/kb/articles/Q119/4/67.ASP> )
...
MORE INFORMATION
The Bcupdate.exe program updates the low-level bootstrap
code stored
on NTFS volumes. All NTFS volumes contain bootstrap code,
but the
code is used only on system volumes.
Because the bootstrap code is a part of the file system and
not a
part of any "user" file that can be replaced, it is not
affected by
the application or removal of hotfixes or service packs.
Once
updated, the boot code remains fixed until the volume is
reformatted
or the boot code is replaced by some other process (such as
that
performed by Emergency Repair when it repairs the boot environment).
Microsoft has no plans to incorporate automatic bootstrap
code
updates as part of a future Windows NT 4.0 service pack
installation.
To update the bootstrap code and resolve a boot issue of
this kind,
it is necessary to run Bcupdate.exe.

EXCELLENT explanation of other components of NTFS, and how
fragmentation in those areas can effect performance:

<http://www.microsoft.com/TechNet/winnt/optntfs.asp>
---excerpt---
..
NTFS Performance Factors
You determine many of the factors that affect an NTFS
volumes'
performance. You choose important elements such as an NTFS
volume's
type (e.g., SCSI, or IDE), speed (e.g., the disks' rpm
speed), and
the number of disks the volume contains. In addition to
these
important components, the following factors significantly
influence
an NTFS volume's performance:
* The cluster and allocation unit size
* The location and fragmentation level of frequently accessed files,
such as the Master File Table (MFT), directories, special files containing
NTFS metadata, the paging file, and commonly used user data files
* Whether you create the NTFS volume from scratch or convert it from
an existing FAT volume
* Whether the volume uses NTFS compression
* Whether you disable unnecessary NTFS behaviors
Using faster disks and more drives in multidisk volumes is
an
obvious
way to improve performance. The other performance
improvement
methods
are [***]more obscure[***] and relate to the details of an
NTFS
volume's configuration.
