pls check the bluescreen minidumps on w500

hi, my w500(4061a62) went to blue screen sometimes when switching network through AC,here are the minidumps,will pls check them for me?THX in advance...

it seems the error comes from wanarp.sys and pacer.sys...
both of them are vista network service drivers(remote desktop and QoS service).

I'm using a vista ultimate 32bit version, all the hardware drivers are latest, I doubts if it is a bug of AC...

 

it often happens when the net cable is unplugged and the vpn connection go dead and I try to reconnect

 

I didn't check the dumps, but if the Default Bucket ID is Driver Fault, and the Image Name is wanarp.sys/pacer.sys, then uninstall the driver, make sure those sys files have been removed, then reinstall a different version (old or new).

Or, if you don't need them, just go to their location (System32/Drivers), take ownership of the 2 files, and change their extension to .old

 

hi,andy
the two drivers are pacer.sys and wanarp.sys...I dont know how to uninstall them or should I uninstall them?
