Trend blocks the IEEE 1394 port
I tried connecting my external hard drive to my work laptop via IEEE 1394 earlier today. For some reason, Windows wasn’t showing it in My Computer or in Device Manager. I tried turning the external drive on and off a couple of times as well as a different cable. Nothing worked so I started to panic thinking that I’d lost my files.
I figured out what the problem was once I remembered another issue I had earlier. The earlier issue was that none of the VM’s I run on my workstation would connect to the network. I had to shutdown the Trend Micro Personal Firewall service in order for them to work properly. We use the Trend Micro Office Scan suite at work so the firewall is loaded by default. Once I shutdown TMPF on my laptop, and reset the drive, everything worked fine.
The weirdest part is the fact that I can’t just disable the TMPF service. If I do, none of my network devices work properly. It has to be allowed to start and then shut down.

That’s one of the strangest things I’ve ever heard!
Trend Micro’s websites barely seem to even reference Firewire and IEEE 1394.
As to disabling the service, is it a dependency for any other services? Naturally you can script this to stop after starting but this shouldn’t be happening anyway.
In regards to the overall problem, have you tried maybe different drivers for the IEEE 1394 controller?
This is a longshot, but do you have any virtual NICs? I don’t know what VM software you are using but those virtual interfaces do some strange things to firewalls at times.
Hi your post is stunning.
I will definitely read your site..

Yeah, I’m with that guy.
I haven’t tried different drivers but I don’t think that will matter. The TPFW seems to “protect” any connections listed in Network Connections. I can’t edit the TPFW options so turning off the service is my only option.
There doesn’t seem to be any other services that depend on TPFW. At least, the Services panel doesn’t show any.
Oops, I forgot Firewire shows up like a network connection. Hmmm… doubt Trend will give much support for a “personal firewall” at work anyway.
