Can someone please give me a vbscript, ini file, reg file, inf file, etc that I can run under Windows NT Server 4.0/2000 Pro that will disable (and enable when needed to) the keyboard and mouse? I am trying to install some software silently and don't want the user to interupt the process.

Only ones I can think of are Hexadecimal, but require a reboot. format is CHR(27)+CHR(NNN) with the N = number. One would lock the Keyboard and mouse and the next reboots. If I remember correctly CHR(27)+CHR(121) is the reboot. Been over 12 yearssince I used it, worked great in a *.bat (Batch file), lock key board at the beginning and reboot at the end (8088 thru 486 technology)

I make no claim as to the value or usefulness of any of the following. None are tested or recommended by me. Simply related as items of interest... Use at your own risk.

The first option that I have for you is using a Win95/98 scripting tool:http://www.oreilly.com/catalog/netpc/excerpt/ch06-04.htm

Next, "Mo'Slo4Biz". This is a shareware app that slows down PI & II systems to run DOS apps. It has a cool feature to disable the keyboard.

The next is used in forensics on some seized PC's:

A copy of the SUBSEVEN Trojan would do it too. 8(

The rest is all programming stuff to do it the HARD way...

There is some old Delphi code athttp://www.delphipages.com/tips/thread.cfm?ID=100
that may help. May not.

Also some assembly here: http://cs.smith.edu/~thiebaut/ArtOfAssembly/CH20/CH20-5.html

A little "C" here:
