Prior to knowing what caused my access problem, I fixed mine temporarily by doing a system restore, then disabling the automatic updates in my windows security center. I know this is what worked because the first time I tried I neglected to disable the updates. The system again downloaded the update causing a second access problem.
may not be a permanant fix, but it was good enough to allow me access to the internet
until a more permannat fix could be installed.
