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.
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?
