ok so here's the deal I went to this website (http://www.mydigitallife.net/2007/0...sys-connection-limit-patch-for-event-id-4226/) and followed the instructions perfectly upon re-start the tcpip.sys driver cannot verify digital signature. I can't get it to boot at all regular or in safe mode, I even tried disabling driver signature inforcement and I get a blue screen that says its dumping information. and I dont have the vista installation cd to re-install, so please help I just need to boot to re-place the original tcpip.sys driver
