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.

Our LAN NT "specialist" (none of us are extremely good with NTWS here) looked at it, but was mystified also, and is not quite sure what to do. Any ideas, short of a complete re-install?
