Internet Explorer - LAN Settings

I am looking for some help and advise regarding LAN Settings in Internet Explorer. I need to go in to the LAN settings to input a proxy. The problem that I am having is that when I go into the connections tab and click on LAN Settings, it throws up the error that "Internet Explorer has stopped working", after 2 minutes it then closes and re-opens. If I try to go back into LAN Settings and click it I get the same thing again.
I am currently using IE9 but I also have tried IE8 and the same thing is happening. I am running on Windows 7 64bit operating system. This issue seems to have only come up over the last few weeks and it has happened to multiple computers. Has anyone seen this issue before and found a work around? Any help is much appreciated. Thanks.

Have you tried Mozilla Firefox or it's absolutely necessary to be Internet Explorer?

Sticking to IE, close all your Internet Explorer windows, then go to Control Panel > Network > Internet Options and see if it works better.

It has to be IE as far as I know as I am trying to activate Microsoft Office 2010. I have tried your suggestion by going into Control Panel > Network > Internet Options and although it soesn't close down my IE is still throws up the following error "Windows Shell Common DLL has stopped working". This only seems to be an issue on Windows 7 also, IE8 on Win XP is fine.

Hi Argenti,
Still no success with your attached solution regarding powershell. I am lost as to what is wrong with this.
Do you have a virus scanner on your machine? Does it say anything?
What do you see in Event Viewer at the exact time the problem started?
(the info log you want is probably in Windows Logs--either Application or System)
You can also look at the Reliability Monitor (Start|type reli|click on Reliability Monitor) and see what information there is in the link in the Action Column.

Argenti - I have Sophos anti virus on my machine and have done a scan and nothing came back, it was all clear.

Apologies, I have been out of office. Anyone else out there have any advice on my question, I have tried the above possible solutions but to no avail.

I'm don't know when the problem started as it's only recently I had to make a few changes and it would not allow me click on the LAN Settings button, it just crashed the application. What area or option in event viewer should I be looking at closely to try pinpoint the time or cause. Thanks
Trying to find an Error in Event Viewer from an indefinite time in the past could be time consuming.  Recreate the situation by going "into the connections tab and click on LAN Settings, it throws up the error that "Internet Explorer has stopped working", after 2 minutes it then closes and re-opens".  Then immediately open Event Viewer, expand Windows Logs and look for Errors in Application and System.

Sorry with the delay, I have followed your steps as regards finding the error in the event viewer. Below is what was returned:

Hopefully it makes some sense to you and you might be able to guide me in the right direction from here - thanks for your help.

See if you can enter LAN Settings from that Connections window

If no help try troubleshooting from a Clean Boot (not a Clean Install).

Do not forget the Reset of the Startup mode when you are finished (instructions on that link).

Unfortunatley neither of the above possible fixes have worked for me. I am still getting the same issue where its crashing. I cannot understand what would be causing this error.
boomsong--You can try a repair of IE using this tool;cat=42&id=133&artlang=en

And you can temporarily disable your firewall to see if that could be the problem.

If no help and in view of the several other fixes you have tried, I would suggest a Repair Install.
This will not affect your personal data or installed programs, though a backup first is always a good idea.  Among the things it will do is reinstall IE.
