You bet buddy... and the DNS issue I would imagine is probably system wide... but it might also be attributed differently between different HA (home agents) Yes, I traveled on I-65 from Nashville, TN all the way up to Indy, then north on Hwy 31 into South Bend and the net was foobarred all the way up. Changing the DNS server is the only thing thats fixed it for me.
Like I said, deleting the CM_Guardian will relieve your 'sticking setting' pains. In any case, by tomorrow its possible that your normal DNS servers will work once again too. I will be looking forward to your response tomorrow! Good luck with the studying!
