I am not sure if this is a widely known problem yet. Fresh install of TMWF9 and then the Professional AD sync tools.
I selected my own custom port for Trend to quirey my AD (6443). (It uses an Apache service)
It will not communicate. I ran up a fake IIS server on this port and it works, so my firewall rules are ok.
I ran “Netstat -an” and noted that the Trend service was running on 0.0.0.0 port 6433. I need it on my server IP on port 6443.
I located and edited:
<drive letter>:\Program Files (x86)\Trend Micro\InterScan Web Security as a Service\AuthenticationAgent\Apache-20\conf
I changed the following
Listen 6443
(Which listens on all free IP’s ports)
To the following (Where I have used my server IP)
Listen 10.0.0.2:6443
All fixed.
