>>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.

Okay, we've repaired the damage. The time for the VGA-selection screen was set to 0, for security reasons. We made a bootup disk that set it back up to 15 seconds, so we can go in and fix it. Machine is now back.

The potential problem still exists on all NT machines, however. We set the res to 1600 on other NT machines, and it hoses the screen settings and renders the machines unusable. It really shouldn't even be available as a setting - no one could possibly use 1600, it'd be way too small to see. However, users (like me) may try it out of curiousity - so LAN is going to try to eliminate it as a resolution setting, and set the max res. at 1024x768.

Another thing that bothered us is that NT is requiring a restart for all the first-time higher res. changes. I thought that was fixed in Win98 and NT4?
