Hi All,

Internet explorer hangs when I access my web site that I have created using
ASP.NET
There is no predictable behavior/ pattern for the browser to hang.
The application uses Server.Transfer to transfer from one page to another.
We have debugged the application and found that the application completes
all the tasks and returns the HTML to the web browser, but the browser some
how is not able to render the HTML.

When the browser hangs, it does not even go to any other web site / web page.
Accessing the same website from another browser or computer works fine.
Therefore it is also clear that the application or the IIS server does not
hang.

What do you mean when you say IE "hangs"? Does your whole system lock up
requiring a restart? Does just IE freeze and you have to quit it via Task
Manager? Any error messages? Is the NET framework properly installed on
that system? Are you using any scripts on your page? Are the security
settings the same on the browser that doesn't work vs. the one that does?

In IE go to Tools...Internet Options...Advanced tab, make sure both "Use
HTTP 1.1..." boxes are checked.

If the NET framework is installed on that computer:
Click Start, and then click Run. Type regsvr32 <Windows
folder>\Microsoft.NET\Framework\<Version Number>\aspnet_isapi.dll, and then
click OK.

If no joy, reinstall it.

Hi Jon
IE actually freezes. We have the security set to low level and the .NET
framework is properly installed on the system.

Yes the page has java script, but the same work properly at our development
centre. The problem is at our client site. We are unable to replicate the
same on our computers.

The behaviour does not have any pattern, the browser freezes abruptly. We
have also checked for Malware,parasites also other softwares that can
interfear with IEandfound none.

Moreover we installed a fresh server for our client, but the problem
persists on the client site.

Any pointers??

Screen freezes with IE are most commonly caused by video drivers that need
updating. Go to the web site of your video card manufacturer and get the
latest drivers for that card. As a work around, try turning down your
hardware acceleration, color depth, and/or screen resolution. If these
work, then new drivers are in order.

Other causes are scripting engines that need reinstalled or updated:
http://msdn.microsoft.com/library/default.asp?url=/downloads/list/webdev.asp

Or the Java VM: http://www.java.com/en/download/download_the_latest.jsp

Some other things to check (you haven't mentioned what version of Windows is
involved):

HTML pages only partially appear, HTML pages do not appear at all, or the
network stops responding

Internet Explorer Displays a Blank Page and May Appear to Stop Responding on
Windows 2000

Internet Explorer may appear to stop responding when requesting many objects

Internet Explorer Quits When You Visit a Web Page That Uses an XSL Transform
and Window.name Property
http://support.microsoft.com/?kbid=811812

I take it at the client's site that IE is updated with the latest patches
via Windows Update?

It seems that all the patches/hotfixes are installed regularly using windows
update. However, I found that a patch related to Q867801 is not installed. IE
at the matchine is IE6 with SP1. When I tried installing the aforesaid patch,
it gave the message "this patch requires SP1 installed", though SP1 is
already installed on the machine. That is the only patch I guess is not there.

However, just wanted to elaborate that the problem reported by our client is
only at two aspx pages. These two pages are part of a three page wizard and
problem mostly comes when user goes from page 2 to page 3. Page 2 is pretty
data centric and has hell lot of controls on it. We use server.transfer for
going from page 1 to page 2. While clicking on a button on page 2, IIS logs
says that page2.aspx POST request and status is 200 OK. Application also logs
the information and we found that server.transfer executes sucessfully,
page_load event of page 3 gets called by framework and finishes successfully.
But browser sometimes freezes and never recovers back.

Also, we checked at the browser end by installing a plugin, giving all the
details of the response. It also says the status of the previous request was
200 OK, says the content length is ~ 30000 and sends a GET request for
fetching .css file assoicated with the page and does not move forward to GET
another images, .js files, etc and freezes.

Any help would save us innumerable hours.

Explain?

That message should be interpreted as: you don't need this.


> That is the only patch I guess is not there.

KB867801 (aka MS04-025) is a very old cumulative security update.
A later cumulative security update would supersede it, hence the message.

Please answer all questions, implied or direct first:

Depending on the OS you may be able to try an IE Repair (ref KB194177)
or check your maintenance level using the MBSA, etc.


Worrying about some specific symptom may be premature
if you are unsure about your maintenance level or the state
of any COM modules.
