Hello Jared,
Thank you for kind update.
The step 1 to 6 is my suggestions in my previous reply. I'd like you to try
them one by one in order. If the 6 suggestions can resolve your issue, we
do not need to perform any gather info steps, and do not need to schedule a
down time. If the all 6 suggestions can not resolve your issue, please
perform the next step 1 to 4 to gather info for me to narrow down this
issue.
Hope these steps will give you some help.
Thanks and have a nice day!
Best regards,
Terence Liu(MSFT)

| wow, thank you for your extensive reply...i noticed that part of the
| instructions require "schedule down time" -- does this apply to the
| section where there might be "incompatibility between web site and
| ISA's web proxy filter" and you give me steps on that? I would like
| to try that while people are still online, but don't want to mess
| things up with the changes...it is hard for me to be here when nobody
| is online...
