Trendmicro Officescan remote install issue

I have Trendmicro OfficeScan 8.0 installed on my win 2003 server. I'm using the web based management to do remote installs on my client machines. It's been working fine but I've run into an issue today. From the web interface it can't find certain client machines. If I disable the firewall on those machines it finds them just fine. I know how to work around this but I want to know what is causing this.
some facts:
I can ping the clients from server
I can ping the clients from my desktop
I'm using the webinterface of the server on my desktop to do the remote installs
These machines are across a VPN.

I've already called Trend's support number and they were no help.
I used a program to see what ports were being used when the firewall was off and it showed 445, but when I tried to add that as an exception it told me it was already part of File and Print Sharing. So I enabled that and it still doesn't work.
Anyone have any ideas?

Network browsing usually works on port 445.
So if your pc block that port then it is logical that the TMC can not browse for it.

you should make sure that outgoing TCP connections on ports 80 and 443 are allowed to the OfficeScan server you are connecting to.

You mentioned that the client PC is connected through a VPN.
Make sure that the VPN software/hardware ( if it is a third party software ) has these firewall settings open as i describe above.

goodluck,

It's something else I think, some of the other machines work fine even with the firewall on, even through the VPN. I called Trendmicro's tech support to ask what port the remote management/install uses but they were no help. They gave me all the ports it uses after the client is installed. Which doesn't help for remote install.
I ended up just turning off the firewall to do the install on the machines that were having this issue. Which turned out to only be a handful.

You can use GPO to disable the Firewall on the client.
That way it is fast and easy.
After you have installed everything, you can set everything back the way you want using GPO.
