>I changed the resolution to very high on my NT machine. It seemed okay for a minute, but then the screen went black, and the last bit of color I saw was a message about "lock-out." The machine (network) boots up to the point of "Last Known Menu", but then gets stuck. Pressing keys results in beeping. NT apparently has nothing comparible to "Safe Mode" of Win9x to get in to fix things.

Bruce, there should be an option to boot into VGA mode; doing that runs the default 640x480 VGA driver. You then fix and reboot as needed.

If that doesn't work, get out to www.winternals.com and order a copy of ERD COmmander Pro. Best thing since sliced bread. Not cheap.
