I should be the one appologizing...
Today I'm having brain farts...it happens. Anyways, yes you can modify
environment varibles with the auotexec.bat / .nt files to modify your
"dos" or 16-bit sessions. However, with some registry changes, it looks
like it might be possible to get the autoexec.bat file to work similarly
to how it used to work for all the 16-bit OS's. I may be wrong though.
With that said... Frankly, I've gotten so wrapped up in trying to say
that I was right (when I was wrong), that I have forgotten what we were
trying to accomplish here. But anyways take a look at this...
Here is some info:
Article 1:
Environment Variables in Windows NT
The information in this article applies to:
Microsoft Windows 2000 Server
Microsoft Windows 2000 Advanced Server
Microsoft Windows 2000 Professional
Microsoft Windows NT Server 3.1
Microsoft Windows NT Server 4.0
Microsoft Windows NT Workstation 3.1
Microsoft Windows NT Workstation 4.0
This article was previously published under Q100843=20
There are three levels of environment variables in Windows NT; the
system environment variables, the user environment variables, and the
environment variables that are set in the AUTOEXEC.BAT file. There are
also some predefined environment variables that are set when the user
logs on. This article discusses the following topics:=20
System environment variables
User environment variables
AUTOEXEC.BAT environment variables
How environment variables are set
How the path is built
Changing user environment variables using control panel=20
System Environment Variables
System environment variables can be viewed from Control Panel by
choosing the System icon. These variables are always set no matter who
logs on and they cannot be changed by any user.=20
There are a few additional predefined environment variables that are set
when the user logs on that do not appear in the System dialog box:=20
USERNAME
USERDOMAIN
NTVERSION (not available in Windows NT 4.0 anymore)
WINDIR
OS
PROCESSOR_ARCHITECTURE
=09
values: x86, MIPS or ALPHA=20
PROCESSOR_LEVEL
=09
values for x86: 3, 4, 5 values for MIPS: 3000, 4000 values for ALPHA:
21064=20
HOMEPATH
HOMEDRIVE
HOMESHARE
=09
These three environment variables are set based on the value of the home
directory. The user's home directory is specified in User Manager
(Choose Profile and Properties). If the home directory uses universal
naming conventions (UNC), then they will have the following values:=20
HOMESHARE=3D\\<server name>\<share name> HOMEPATH=3D\<path> =
HOMEDRIVE=3D<drive
letter>:=20
If the home directory is a local path such as c:\nt then they will look
like this:=20
HOMEDRIVE=3Dc: HOMESHARE=3D HOMEPATH=3D\nt=20
All above environment variables are always present and therefore may be
used in log on scripts.=20
User Environment Variables
User environment variables can be viewed from Control Panel as well. The
user may add, delete or modify the environment variables in the User
Environment Variables for User field. These variables take precedence
over system environment variables. The user path is appended to the
system path.=20
AUTOEXEC.BAT Environment Variables
All environment variables and the paths set in the AUTOEXEC.BAT file are
used to create the Windows NT environment. Any paths in the AUTOEXEC.BAT
file are append to the system path.=20
How Environment Variables Are Set
Environment variables are set in the following order:=20
System variables
AUTOEXEC.BAT variables
User variables=20
How the Path Is Built
The Path is constructed from the system path, which can be viewed in the
System Environment Variables field in the System dialog box. The User
path is appended to the system path. Then the path from the AUTOEXEC.BAT
file is appended.=20
Note: The environment variables LibPath and Os2LibPath are built the
same way (system path + user path + AUTOEXEC.BAT path).=20
Changing User Environment Variables Using Control Panel
User environment variables can be added, changed or deleted from Control
Panel. There is no need to reboot after making any of these changes.
Changes take effect immediately after exiting the System dialog box.=20
The next application you start will use the new settings. All other
applications running before the changes were made will not recognize the
changes.=20

Article 2:
Windows NT usualy does have an AUTOEXEC.BAT and CONFIG.SYS, but doesn't
use them by default.
To use AUTOEXEC.BAT to set environment variables in command line
sessions you need to add or modify the following registry setting:=20
[HKEY_CURRENT_USER\Software\Microsoft\Windows
NT\CurrentVersion\Winlogon]
ParseAutoexec=3D1
Set it to 0 instead to disable it.
Warning: To use this feature you need to edit Windows NT's registry.
Changing the registry manually is a potential risk to your system; it
may never function again.
Use this information entirely at your own risk.=20
Windows 2000 allows the use of any AUTOEXEC.BAT like startup batch file
for command line sessions by introducing the AutoRun registry key, as in
this example:=20
[HKEY_CURRENT_USER\Software\Microsoft\Command Processor]
AutoRun=3DC:\STARTUP.CMD
Replace C:\STARTUP.CMD with any other batch file you like to run at
startup of command line sessions.

Sorry,=20
Lets clarify shall we, NT/2000 uses autoexec.nt for dos programs when
they run and if specified. Autoexec.bat is NOT used in NT/2000 as it is
used in 95/98. It only sets ENVIRONMENT variables. While it may be
there you can't run a script from it at system bootup.=20

If you check for hidden files on your NT server on the root of the boot
drive...you will see there is, in fact, an auotexec.bat that can be
used. =3D20

FYI Lucas, Winnt TSE has no autoexec.bat . . Only autoexec.nt which is
only used when 16-bit apps require the usage of DOS startup paramaters.
In other words, it doesn't run on boot.=3D3D20
Check out Jim K's responses to this one. Aside from the tools he
mentions, there are a couple of utilities from the NT resource kits
which can be used to make CMD or BAT files into controllable NT
services, which will launch on boot.=3D3D20
Do a search on google for "create an NT service", ignore the programming
links and you'll see some Q articles in there.=3D3D20

Try putting it in the autoexec.bat file. Either that or in the
system.ini file under the run=3D3D3D3D line.

I want to run a script that runs the SETPRFDC program whenever a server
first boots up. What is the best way to do this? The servers are winnt
