Nobody is perfect, and no software
is perfect !
Although Microsoft has done its best to test Windows NT4 before
releasing it, some "bugs" are only found by
the users, sometimes in very specific configurations.
The fixes are made available to users as: Service
(Dec. 1, 2000: current version for
Windows NT4 : Service pack 6a, often just called: SP6a,
note: there is a Encryption Conflict between IE5.5 and SP6a )
There are now software
packages/updates on the market, which check (and
insist), that a minimum level of Service pack is
installed (so sometimes you have no
choice, you are forced to install it).
The Service Pack MUST match your
Windows NT version in the Language
and version (and the US-version is NOT the
same as the English-International version !)
They are getting delivered with new NT4 systems as additional
CD-ROM (at least with new HP systems), but they can also be purchased.
The Service Pack CD-ROM is Auto-Play and starts up your
Just click on "Install
Service Pack" to
start the installation.
But you can also download the Service Pack from http://www.microsoft.com , follow the links to "Free Downloads" /
"Windows NT Service Packs":
Do you really like to download 18 MByte for
SP4 or 34 Mbyte for SP6a ?
The downloaded file needs to be expanded for installation.
Also, since you will need the Service Pack
fairly often (see below), even if
I have the CD-ROM, I prefer to copy all files of the Service
CD-ROM to disk location (I use: C:\SP3) (to
have it in fast and convenient access).
To start then the installation, locate and start: UPDATE.EXE:
||You get the Welcome message.
||You need to accept the
Microsoft License Agreement.
||Select to install the Service pack.
(running UPDATE.EXE can also
be used to un-install
a Service Pack)
||But to be to UN-INSTALL
the Service Pack, you have to
create an UNINSTALL directory
(so that the system can save the files
of the current s/w version)
||Files are copied
||and you will need to reboot.
I hope, that you did read (and
memorize) the above message:
|If you change or add any
component to your system,
you will need to reapply the Service Pack
that means: install the Service Pack
This is a MUST !
(Example: Service Pack 3 was installed on a
system without networking,
you install networking and without reapplying the Service pack,
your network will
NOT work and you get in the event-Log the message: Not Enough Server Storage )
Need to know, whether (and which level) a
Service pack is already installed on your system ?
Start the "Windows NT Diagnostics":
||Although it shows "Service
it could also be "Service Pack 6a",
but which is installed ?
To my knowledge, the ONLY
method to identify an installed
SP6 or SP6a is the "WINVER"
(run it the START-menu,
from a command-window)
