How UPnP failed me and Bonjour for Windows saved me. Today I am working in an Windows XP environment entirely. Not just a Mac found. However, it was Apple software that kept me. We just got a new Axis Q1755 network camera. It supports Universal Plug-and-play or UPnP.

It also supports Bonjour which it turns out is very lucky for me. The camera was linked by me to our network. At that true point, as a UPnP device it is supposed to show through to my OR WINDOWS 7 computer inside My Network Places. I opened up My Network Places, and it wasn’t there.

I found an article that said Windows Firewall can interfere with UPnP devices. However, since I’m on an internal network, I’ve my Firewall turned off. I came across another article that pointed out that by default OR WINDOWS 7 might possibly not have all the needed UPnP software installed. Add or Remove Programs.

I clicked the Add/Remove Windows Components button. I clicked Networking Services. Then I clicked Details… I saw that UPnP INTERFACE was not examined, so it was examined by me to set up it. Clicked OK, then Next, then Finish which installed the UPnP components. Opened My Network Places again, but nothing still. I found just one more article having said that I would need to enable the UPnP discovery service.

Services and appeared for the SSDP Discovery Service. Affirmed, it was handicapped. I enabled it and began it. I verified its status changed to Started. Closed the assistance control -panel. Opened My Network Places again, and still nothing. Now I’ve already wasted 10 minutes on something that was supposed to be Plug and Play.

Then I noticed in the setup manual of the camera it also supports Bonjour for Mac OS X. Hmmm I understand Apple released Bonjour for Windows too. It can’t work any worse then this, and if it requires less then 10 minutes it’s a more efficient use of my time. So I go to the Apple website and download Bonjour for Windows. It installs a fresh button on the Explorer Bar in Internet Explorer. I click that button and it discovers three devices on my network immediately. Two printers, and my new Axis camera. I go through the camera and have full access to it.

Unfortunately, redirects usually fall under that category if the person doing it doesn’t really know the importance of it. Another plain thing with deadlines is inner deadlines. Sometimes perhaps you may have a deadline for a quarterly game or a monthly game. We must have our projects done by this date. A similar thing with the deadlines. The redirects are usually however something that will skip the cutoff for those types of things. Then another situation that can cause site migration 404s and mistakes after active is non-SEOs handling this. Now you don’t have to be considered a really experienced SEO usually to handle these kinds of things.

It depends on your CMS and how complicated is just how that you’re implementing your redirects. Those are all situations that I’ve came across issues with. So given that we kind of know very well what I’m talking about with migrations and why they kind of sometimes still happen, I’ll launch into some guidelines that will hopefully assist in preventing site migration mistakes because of failed redirects. Number one, always create one-to-one redirects. This is super important.

What I’ve seen sometimes is oh, man, it could save me tons of time if I just use a wildcard and redirect all of these pages to the homepage or to your blog homepage or something similar to that. But what that tells Google is that Page A has shifted to Page B, whereas that’s not the case.

You’re not moving many of these web pages to the homepage. They haven’t actually relocated there. So it’s an irrelevant redirect, and Google has even said, I think, that they treat those as a smooth 404 essentially. They don’t even count. So be sure you don’t do this. Make sure you’re always linking URL to its new location, one-to-one every single time for every URL that’s moving.
