La'teeno,
correct me if I'm wrong, but when you say you want to install NT from the
network, I assume YOU mean from the Internet.
What a network installation is, is one from a LAN or a WAN, eg a company
network.
If this is what you mean, then you have to go to the \i386 directory, and run a
file called WINNT.EXE. Upgrading an existing NT package, you would use the file
WINNT32.exe.
I'm no expert, but I do know you cant install Windows NT from the Internet.
Hope this helps a little.
