Recently we replaced our KVM
As a result the PS2 ports on some servers are not working with the keyboard and mouse.
We have isolated the problem and it is not caused by the KVM, hardware or the cables.

We cannot get the server to respond to the keyboard or mouse plugged directly.

I know that its likely the keyboard and mouse will work if we could restart the server.   However we do not have this option available during the next 12 hours.
We need to get the keyboard and mouse working urgently (without reboot) using a command or tool that refreshes the PS2 ports.

Is there a dos command or software tool we can run to refresh the PS2 ports?
We can connect to the machine using remote desktop.

Thanks.

In Device Manager, try deleting the ports and see if you can identity the devices after a refresh.

Hi,

PS2 peripherals are first detected by the bios. Then frowarded to your OS. IF the problem is your bios, you're stuck anyways...

If your problem is Windows related, you might try to reload/update the drivers for your devices in the System Properties : Hardware > Properties > Driver > Update Driver. You can also scan for hardware changes there (right click option)... It depends of your version of Windows...

Good Luck,
P

Hi Piloute and Vicky,

You both pointed us in the direction of the device manager (win2k3)
If I change the view to show hidden devices - I can see the keyboard and mouse items.
They have a question mark on the device.  I "Scan for changes" and it doesn't re-detect the keyboard and mouse.  I tried update and I don't have any newer device drivers to install.
I uninstalled the device and then scanned for changes. Hoping to refresh / reconnect to the mouse and keyboard.  I was hoping Plug and Play would do its thing.
Now the device is uninstalled and I don't suppose there is a way to get it back other than trying the reboot (after hours).   I'm trying to remember how the startup procedures work.  Something with POST or Keyboard Bios?

I think there's no software to force this proceedure that happens on startup.  I may have no option but to reboot after hours.

Sorry, it looks like a reboot is the only way for the system to re-connect to the keyboard and mouse.
