My Windows XP Pro will not accept webcams for some reason - it happened before I installed SP2 and it is still happening. I have tried at least three different brands and it won't have it. Even my Fuji digicam won't act as a webcam with it!
I have 2 SP2 CDs from Microsoft, but I downloaded SP2 originally through Windows Update. I have considered getting one of the webcams listed on the scanner/camera installation wizard as those drivers are included with XP...
Firstly, make sure that you have the latest version of the Instant Messaging client you are using. Go to their web/forum site to check whether other people have similar problems.Often you have to upgrade or add a patch. Somewhere you will see that your messaging client will need certain Ports or a group of Ports, to be opened for it to be able to function properly. Do not assume that these ports will automatically open when you log on. Most ports not in use (nowadays should be closed, since SP2 especially) should be closed for security reasons. You can open the necessary Ports manually,while you are using the Webcam and then close them when you have finished, for the sake of security.For a trial connection you could simply turn off your Firewall protection. Firewalls have caused most webcam connection problems. I am not sure why this function is not made automatically when you use the program, maybe they have already incorporated this feature by now. The security aspects have put me off using my Webcam as much as I would like to. It is a very intimate way of communicating, and very pleasant, and time consuming.
I haven't got far enough to see if a webcam will work with my messaging programs yet. For some reason, XP (I think that's what the problem is) won't even recognise them. The error message says that the software doesn't install properly. I even tried downloading the latest software for them, but that doesn't work either. It's probably something obvious, but I might be looking in the wrong place. My device manager just lists them as unknown devices.
