hi i ran throgh that article, its exactly the same as the one i used fron that testlabs website

aslo my firewall has two nics internal & external so no problems there

what does it mean unauthorised response from isa? is isa blocking it?

what do i need to monitor to see the result from isa?

ok im not using secureID so all should be fine there

i changed authentication on the TMG rule from authenticated users to all users, now i get

A Web Exception occurred because an HTTP 401 - Unauthorized response was received from IIS7

this would be iis7 on the exchagne yes? as iis isnt installed on the TMG

under iis7 > Microsoft-Server-ActiveSync authentication is set to basic only, is that right?
