Web page displays on Host ie11 but not on another machine, have I missed something? - iis

i have an asp.net web site made to simply allow people to update some sqlserver tables.
The website works perfectly on the host server in Edge and IE11.
On other machines when accessing the server like so :
http://server.net/8081/homepage.aspx
It works in Chrome and Edge.
however in IE11 it displays wrong. Some colours come across, all gridviews appear correctly but layout is literally bonkers.
Is there something simple i am missing? This is my first time publishing a site in asp.net. all help appreciated.

Microsoft Edge and Windows mobile download my product page instead of showing it normally

I'm developping an online shop with PrestaShop 1.6.1 on an Apache server. I have no problem with Firefox, Chrome and Safari. But on Microsoft Edge (on my computer) and on my Windows Phone, the product pages does never show up. All other pages are ok, the issue is only when I try to open a product page with Edge or with my Windows Phone.
What is the issue? What can I do to solve it?
As supposed by arkascha (thank you arkascha), the headers sent with my page were wrong.
The file product.tpl of my prestashop theme contained a line:
{header('Content-Type: #slider_row')}
I replaced this line by:
{header('Content-Type: text/html')}
And now, it works fine. Problem solved.

Ads appearing in our application when they should not be

I had a strange issue from one of my customers this morning, who use my web application. Apparently they are getting "ads" within the browser window when using my application.
I do not put ads in at all. It a straight forward asp.net web application.
What I believe is happening in this case is that the end user has some malware on their pc which "hops" onto their browser session to display their "wares". It could happen to any website they are perusing I guess. I recommended they scan their pc with Malwarebytes.
Is this something that is under the control of the end user, or are there things web application developers can do to prevent this happening. Also some pointers as to how these "ad browser hijackers" work would be good.
Thanks.

not able to access mywebsite in webbrowser

My server with this IP is working and can able to view the updated data in database ..but not able to view, or open the page of website.before the website under IIS configuration was stooped and now started again..still no use..am couldnt view Login page at all.My application was developed in classic asp long back.Kindly give me any suggestion to this...its very urgent...
I tried browsing the website in IIS manger(server) .It showing page cannot be displayed.
Thanks in advance.
First, Don't Panic. Staying calm can avoid further damage.
While it's hard to tell what could be the problem, the first thing you can do is to "ping" the domain from terminal.Can you login remotely? "wget" (on linux) will download the files from website, and could help you see if the files on the site are still accessible. Check from different browsers or machines, if possible. I'm no expert in asp or IIS, so won't advice on that front. But once I had faced the same situation with my website. So I just called up the hosting service provider, and it turned out it was their problem, and they brought the server online. If it's okay from their end, you might have changed some configurations in your server or application or there might be some up-gradation changing parameters, or even an accidental deletion/ moving/ renaming of files. Just try to remember what are the things you did with your server and application, before it went down, and also ask your server administrator. That will surely help you understand the problem better, if not help to solve it right away.
Good Luck.

Having problems to load images in Opera Browser(login popup)

I think this should be releated to IIS settings but don't know exactly what it is.
As you can see below, this login message pops up for each images, 8 images 8 times in Opera.
And the major browsers react to this page different.
IE9 works good(this is the reason why I found this problem now. It's internal site and almost every users use IE...)
Chrome(17.0.963.56 m) works good.
Safari(5.1.2) is also good.
Opera 11.61 has a problem like I said...
And FF SHOWS NO IMAGES and don't even ask for login. And Firebug says it's "NetworkError: 404 Not Found!".
I don't know what's going on.
This site requires to login and it's internal, so I can't give you the link. Sorry for the inconvenient.
And this site is running on Windows Server 2003. And the image containing folder is shared for web(I don't know why it's shared. But don't want to change the setting). I don't know this may cause this situation.
If Opera opens a user name/password dialog, the site is probably sending a WWW-Authenticate header in response to those image requests. You can open Opera's developer tools ("Tools > Advanced > Opera Dragonfly" or right-click in page and select "Inspect element") and use the network feature to inspect the full headers.
I don't know how you can disable this header if it is sent, it depends on the server settings and what type of server you're running, and I'm not at all familiar with Windows Server 2003.

Chrome fails to show http authentication window

I am developing a Drupal site, within which is a page with an iframe, displaying an external SQL Reporting server driven site.
This iframed site is protected on by HTTP authentication. In all browsers, apart from Chrome, when the page is viewed, the browser driven login box pops up.
In Chrome (Windows & OS X), no login box appears and I get an immediate 401 error from the SQL Reporting Server. I've cleared cache's and even tried on a fresh chrome installation on a VM.
The above method works fine on the clients existing live site, which is ASP driven. Other than CMS technology, the only other obvious difference is domains.
The working live site is referencing a sub domain of itself in the iframe. The development site is referencing a completely different domain.
I've tried /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome -–allow-cross-origin-auth-prompt, which seems to make no difference.
Does Chrome have much tighter cross domain login rules? Or am I missing something else?
According to the devs at chromium, this was an intentional change to protect against phishing attacks. If you say the prod sites reference the same domain, you shouldn't have any issues.
http://code.google.com/p/chromium/issues/detail?id=91814
To switch the (in my mind stupid) security-feature off set Browser flag:
--allow-cross-origin-auth-prompt
In Linux close all Browser Instances and type in terminal:
chromium-browser --allow-cross-origin-auth-prompt
For Windows, Mac, Android... take a look here: http://www.chromium.org/developers/how-tos/run-chromium-with-flags
See http://www.chromium.org/administrators/policy-list-3#AllowCrossOriginAuthPrompt for the policy that can be set versus using flags.
On Windows this can be set via the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome. See http://www.chromium.org/administrators/policy-templates for more information.
