Henry,
Just wanted a general rundown on how ISA controls Internet
access etc TBH.
Wanted to know if there were any factors determining how
it could slow performancec down as the nework BB seems
slower than at home.
I don't suppose i am comparing apples with apples when you
run through the list of all your factors.
It's not drastically slower just a little slower but ever
so slightly noticable to a hardened surfer like myself.
It's nothing to spend any length of time though.
Thanks for all the advice/Info Henry really appreciate the
work users do on these web type forums..
