IE7 Browser Error

[mickeyh080]

Having a major headache that I was hoping someone might be able to help with. We recently had an IP camera installed to keep an eye on the sicknote students in the infirmary. The camera has a fixed IP and is registered in DNS as Infirmary-Camera, the software is installed on a server and can be accessed on the server through IE7 browser typing the IP address or infirmary-camera yipee. So whats the problem I hear you say. Well I cant seem to get almost any other computer browser to openin the web interface without getting an error 400 bad request, stating that the web site was accessed but could not open. This error after googling it does not really give me an clues.

The reason I said almost all is that I tried today a new out of the box Dell laptop which is not on the domain and hey presto it connects to the interface no probs. I therefore think there is something in one of the group policy's that is stopping the browser from accessing this site. But for the life of me I cannot seem to find anything obvious.

The browsers on all the school machines otherwise function as advertised displaying the intranet and internet pages wth no probs.

Any suggestions would be grateful, I'm hoping I've just missed something obvious especially in the chaos of this first week back. But need to get this resolved as managemnt are on my back.

If you have network printers, can you successfully connect to it by IP? (exactly the same as with your IP camera) from the workstation and server?

So your camera might be 192.168.1.10 and your printer, 192.168.1.11.

[SYNACK]

What kind of authentication does the cammera use, also does it use a whole bunch of java or some other dynamic language in its interface. You may need to additional to the trusted sites list in order to tell IE that it is alright to run the active components and authentication method required.

Do connect to the internet via a Proxy server?

You might need to put the IP address in the proxy expection list in IE.

Just an idea.

You might need to put the IP address in the proxy expection list in IE.

I was thinking the same, so you'd put 192.* in your exceptions list.

Tools > Internet Options > Connections > LAN Settings > Advanced

You can also do this using Group Policy -

User Config > Windows Settings > Internet Explorer Maintenance > Connection > Proxy Settings

[SYNACK]

You may be able to get around it if it is a proxy issue by bypassing the proxy for local sites and then using the fully qualified domain name of the cammera so that it is identified as local: camera.school.local

[mickeyh080]

Yes can succesfully get to any printer interface via both IP address and DNS name

[mickeyh080]

The camera is a LevelOne FCS-1010 Pan and Tilt colour IP camera. Documanetation is very basic so not sure on the authentication issue. To connect to the control interface you just need to enter root and the set password. This works fine from the servers.

On the client desktops the proxy controls are set to bypass for local addresses and in the exception list I have added a wild card for all IP addresses on a set range which includes the camera, so by passing the proxy for these addresses. Still no joy.

Strange how it does not even open up the interface to allow the password to be entered just get the IE7 error 400.

[Michael]

SYNACK might have a point there. Try installing the latest Flash, Shockwave and Java plugins.

[mickeyh080]

Have Flash Version 9.0.124, Shockwave 11.0 and latest Java 6.7 installed.

Nice thought though.

Thanks for the suggestions so far, its good to bounce ideas off others.

[mickeyh080]

Thanks to all for there input. The cause of the problem is Microsoft Silver Light. Uninstalled the offending item and hey everything works as advertised.

[Michael]

I thought it was strange. I don't use Silverlight myself and this is all the more reason to avoid!

[mickeyh080]

Silver Light in my case is installed on quite a few domain machines via windows update on the desktop we used to create the image. At least now I can remove it on machines intending to access the camera. Think I'll probably take it off any future images as not sure of its real benefit.

Silverlight is an alternative to Flash, but I personally would stick with Flash.
