Thanks for the update! Although my work-around was successful in the short term,
I'm still experiencing the occasional login delays and have to manually perform gpupdate
sometimes as well. I will check my DNS settings against this summary since this is
probably where I went wrong.
I have the reason WHY this happened for us... our knee-jerk reaction to the DNS flaw
was to point to DNS.org which meant changing DNS settings without fully understanding
what we were doing.
