How can I prevent users from pressing F8 when the computer is booting up and
viewing the list of boot options? or more specifically them being able to
boot in safe more with networking.
 
There is no way, to the best of my knowledge. What are
you trying to do that you need to prevent this from
happening?

Hello!
The file ntldr found on the root of the boot disk ( c:\ )
checks F8 and runs the safe mode menu so this needs to be
replaced by a modified version, which was created by
Michael J Reynolds..

1. Download www.myriadworld.com/support/download/ntldrnof8
http://www.myriadworld.com/support/download/ntldrnof8

2. Open a dos window (start/run/cmd) and type
attrib c:\ntldr -s -h -r

3. Copy the ntldrnof8 to ntldr

4. Then reassign the attributes
attrib c:\ntldr +s +h +r

5. Reboot and when you press F8, it will be ignored.

What does this Deepfreeze program do?
If the users only have domain accounts, and no local
accounts on the system, they still have to be validated
by the DC.
 
The problem with this is that it assumes that nobody can
just reverse the process. With physical access to a
computer, one can do all kinds of things, including
getting around this hack. It's rather simple to get back
to a state where I can press F8 and boot to safe mode, or
do all kinds of other stuff that doesn't even require me
to let NTLDR take control of the machine.

My understanding of the DeepFreeze program is that is an excellent
program, very useful where you have many computers like in a lab or
work pool situation. It's also a fairly expensive program, which means
they should have some good tech support. Call them and talk to them
about the best way to use their program. And, as mentioned, if I have
physical access to your computer, I can get in. Maybe you need to think
about who is hitting F8 and why and deal with the problem from a
personnel viewpoint instead of a technology viewpoint.

Good luck,

Malke
