Hello, guys. I have a problem with web access through TMG server Enterpise Edition. When I turn on Url Filtering and create deny rule to several Categories (porno, Online Communities and etc), browsing from internal network is very slow. When i turn off the rule all work great.
It's my perfmon counters
If i create blocking rule and used by destination Domain Name Set, it's working great too.
What's the problem with using Microsoft Reputation Services? Thank you.
