I am using the very latest build of CUPC 8 on a HP laptop. Its running XP Professional SP3. When I am on a wireless connection everything works perfectly. When I am on a LAN connection and using the softphone, everythign works perfectly. If I try to use a LAN connection and connect to my desk phone, I get a BSOD every single time. It will log in, contacts will populate, and a few seconds later it will blue screen.
So far I have updated my network drivers, updated my VPN client, and updated CUPC.
On Windows 7, all is well. TAC hasnt been very helpfull as I cant even get a response from them. Has anyone seen anything like this?
