No Mouse after Reboot

[SKent]

Here is one for you .. I have a network comprised of server and 1 workstation .. W2K on both .. the other night I shut off the system because of weather .. everything was working fine. I rebooted the system and lo and behold .. neither machine acknowledges a mouse being attachted ... this has to me more than coinsidence ... I did all the normal trouble shooting and still can't get it to see one out there ... any ideas ?? I ran McAfee and is didn't find any kind of a virus connection ...

This is happening to me periodically on one of my PCs I upgraded from Win98. Either of these machines an upgrade? When my PC fails to detect the mouse, it also fails to detect the keyboard as well, so when I get to the CAD login screen I'm forced to reboot. It doesn't happen often enough for me to give it more attention.
When you say you've done normal trouble shooting, I'm guessing this included swapping in a known-good mouse, and it's still not detecting it?

I had a call about a month ago for user that had someone "cleaning" out their registry of unnecessary stuff. Well it just so happened that the person rebooted the machine after doing this, and no mouse OR keyboard was detected or working. Well you'd think no biggie, but PNP doesn't happen till a user actually logs in! I had to connect to this user's PC on the LAN and delete the following registry entry (took out the keyboard entry since you don't need it):

Using regedt32 go to key: HKLM\system\CurrentControlSet\Control\Class\{4d36e96f-e325-11ce-bfc1-08002be10318} go into the UpperFilters key and delete the 'lmouflt2' entry.

Note - You MUST use regedt32!

Yes .. I tried it on both machines .. the machine acknowledges a keyboard just fine ... B5passat .. I assume the key register you gave me was for the mouse .. and you say I should delete this ??? what is the entry for the keyboard that I need to delete .. do I understand you right that this will enable PNP during the reboot .. also I tried to add hardware once I was logged on and PNP still didn't see anything out there ..

Yep, delete that one entry, and it should find the mouse again. You shouldn't need the keyboard one since you said that was working, right? In case you do, here it is:

Using regedt32 go to key: HKLM\system\CurrentControlSet\Control\Class\{4d36e96b-e325-11ce-bfc1-08002be10318} go into the UpperFilters key and delete the 'lkbdlt2' entry.

This basically resets the PNP for the devices that you delete, and that key will be regenerated upon reboot.
