We had a bunch of Windows 2008 servers configured by a tech, then racked with and hooked up to an IP KVM. Unforunately, the monitor used during configuration was a widescreen LCD, and now Windows is initialized to a resolution out of range for the KVM as well as the screen onsite.
We found that we can edit HKLM\System\CurrentControlSet... and then reboot the machines. But I'd prefer not to have to make all of them reboot.
Is there a way to restart the video driver or otherwise change the console resolution remotely, without a reboot?
You can use
ResSwitch
from this page: http://www.codeproject.com/KB/tips/resswitch.aspx.This is a little cheeky but you could do it onsite blindly :D
Here's how you'd do it in windows XP:
Oh I should add - DON'T DO THIS.
I've been able to do it using VNC if you can install that via an RDP session, it doesn't require a reboot and you can always uninstall it when done.
