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.
