I recently was setting up port forwarding for a DVR at a business. They wanted to watch the DVR from a remote location and port forwarding with password protection was the easiest solution. Once I had the port forwarding set up on the router I set out to the remote site to set up the URL for the remote computer. What I encountered was an IE security error message that blocked the installation of the remoteweb.cab ActiveX.
What I first did was lower my security setting so that all ActiveX would be allowed and tried again without any success. I then put the URL in the Trusted sites and tried again only to fail. At this point I went to Google and found a couple of MS MVP’s that had left someone with the same problem some snotty answers. There was one intelligent answer from a MCSE but it was the first solution that I had tried.
Bound to not let this kick me for more than 15 minutes, I decided to lower the settings in the Trusted Sites to the lowest settings I could. I went back to the site, where low and behold the install worked perfectly. After it was finished and I could see the DVR, I went about moving the security settings in both the Tools > Security > Internet and Trusted Sites back to their normal settings.

My last check was to restart IE and test the port forwarding site again, which was a smashing success. What this shows is that you shouldn’t listen to titles like “MS MVP” or “MCSE” as gospel. You can get good answers in all sorts of places, you can even find them yourself with a little persistence.
