I have a windows 2003 server that is having an issue with a non responsive keyboard.
The keyboard stopped working after Microsoft connected remotely to troubleshoot an issue.
The device shows up in device manager with no marks (x or !)
When disconnected from USB, it does remove itself from device manager.
I have tried several things in searching for a solution.
The keyboard has been replaced multiple times with both used and new keyboards.
The issue persists even with a ps2 keyboard.
I have removed the item from device manager and had it check for and reinstall the device.
I have deleted the device in device manager and restarted the server allowing it to find the device (which it does).
The device works prior to the windows environment starting.
Multiple usb ports have been tried. (both built onto the mainboard and on a card)
I have replaced Usbehci.sys, Usbhub.sys, Usbport.sys and Hccoin.dll with known working copies.
Currently I am only able to remote into this machine.
This is our main server so restarts are to be avoided unless absolutely unavoidable, and then only after hours.
Thanks in advance for any help on this issue.
