I have an ASP.NET (framework 2.0) web app running under IIS7.
When I run the app on the server, using IE8, localhost the app runs the way it is supposed to.
When I run the app in Visual Studio 2008 (framework 2.0) it runs the way it is supposed to.
But when I try to run the app from another computer it renders incorrectly.
Same versions of IE8.
What would cause the serving of an ASP.NET application to render correctly on the server, but incorrectly when serving to another computer, when the Internet Explorer versions are the same?
Can anyone help?
You can force IE to work in a specific compatability mode with one of the following meta tags in the head:
<meta http-equiv="X-UA-Compatible" content="IE=4"> <!-- IE5 mode -->
<meta http-equiv="X-UA-Compatible" content="IE=7.5" > <!-- IE7 mode -->
<meta http-equiv="X-UA-Compatible" content="IE=100" > <!-- IE8 mode -->
<meta http-equiv="X-UA-Compatible" content="IE=a" > <!-- IE5 mode -->
Here is a link to more information regarding the compatibility meta tag:

One other thing you could try is to save the output source on each system and then compare to see if they are the same. If they are identical then it comes down to the rending on the client which is a compatibility setting.

I have done my project in asp.net with using webmethod concepts. I deployed it in live server. Clients are using windows 8 with IE 11/9. When users used my projects then IE version are changed to IE7. webmethod and json does not support IE 7/8. but when this page open then its automatically IE version changed and display 'JSON object' error. I tried to changed IE default version 9.but its automatically changed IE 7/8. how to change IE default version 9. what is the solution for my problem?
I feel you are talking about the compatibility mode. Try adding following meta tag in your layout page or master page.
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
The X-UA-Compatible meta tag allows web authors to choose what version of Internet Explorer the page should be rendered as.

When I run my project in IE10 in my local, it works fine. But when I deployed it on the server, my pages are not displaying as it should be and it is not working properly especially those parts with javascript. Can anybody help me?
Thanks
Probably the brower displays them with the engine of an older IE.
Try adding this in the head of your html/asp files:
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
Try running a tool like Fiddler. It could be that there's missing css or javascript. Any missing resource will show up in red.
Are you using any browser detection in .NET (i.e. HttpBrowserCapabilities)? If so, it may be due to a bug where IE 10 is being seen as IE 1. Try applying the hotfix for the version of .NET you are using from this page
I was facing the same issue and adding the below line solved the problem
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
In IE 10, if you check the developer tools, you can see that there are two modes for the browser:
Browser Mode
Document Mode
By adding the tag below:
<meta http-equiv="X-UA-Compatible" content="IE=9" />
One is able to force IE10 to render the page in IE9 document standards.
Is there a way that ASP.Net can force the browser to change the Browser Mode to use IE10 Compatibility View or any version lower?
I have an application that seems to break down with IE10, but trying the app in IE10 Compatibility and IE lower versions Browser mode, the application works perfectly fine.
Appreciate any help.
Update:
Posted screenshot of the browser mode and document mode.
If I added the meta tags above, I get:
Notice that the Document Mode is in IE9 mode as specified in the meta tag.
But my application needs to change the Browser Mode (IE10) to something like IE10 Compatibility Mode or lower. Using the current IE10 mode, breaks the application.
You can force the browser to use the most recent by:
<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />
If you want to use lower versions, just change the number:
<meta http-equiv="X-UA-Compatible" content="IE=7" />
Will render for IE 7. But you see to know that from the example you posted. Not sure what else you are asking though.

I am having a similar issue with my app not behaving correctly on IE10. I discovered that my issue is related to the ASP.NET browser definition files not recognizing the latest IE:
[Source: http://support.microsoft.com/kb/2600100 ]
By default, ASP.NET uses sniffing technology for the user agent string
to detect browsers. The browser definition files cover a certain range
of browser versions. However, as the version numbers increase, ASP.NET
might not recognize new versions of a browser by using the user agent
string. In this case, ASP.NET might handle these versions as an
unknown browser.
Links for the hotfixes:
.NET 2.0 SP and .NET 3.5 SP1: http://support.microsoft.com/kb/2600100
.NET 4.0: http://support.microsoft.com/kb/2600088
So, I have an application that I test on my VS2010 virtual ASP.NET server, when I open it in IE on my local environment, everything renders fine, but whenever I deploy it to the external server, it starts to screw stuff up in IE (CSS and some jQuery problems). I have the same code everywhere, how is it possible to be rendering it differently? (I test them in the same IE version), everything works fine in other browsers.
It sounds like a compatibility-mode issue. In some cases, IE will jump into compatibility mode unexpectedly. This is often related to browser configuration.
Easiest way to preven this is to add the following meta tag to your HTML code:
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
This will force IE to always use the best available rendering engine, and prevent it jumping into compatibility mode, regardless of the browser config.
Hope that helps.
We have an old project lying around with these <meta> tags in every page. This website is an intranet web application.
<meta name="GENERATOR" content="Microsoft Visual Studio 7.0" />
<meta name="CODE_LANGUAGE" content="C#" />
<meta name="vs_defaultClientScript" content="JavaScript" />
<meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5" />
Do they have any value or use?
Is it safe to remove them?
I'm using VS2005 if that matters for the intellisense.
They have no use for web clients (other then leaking information about your development environment and using up bandwidth) only for your development environment.
I believe that the vs_defaultClientScript and vs_targetSchema are used for intelisense. You can remove the other tags without any problems.
On some machines it can cause slow loading of the page in IE 11, but it's not clear, on what it depends. Just one user in the office had problems - had to wait 5 - 10 seconds for loading the page, which other users saw immediately... on same Win 7 and IE 11. I removed
and it's OK.
