IE11 user agent - different on different servers, the same app

We have a problem with logging into out app on IE11 on production server. On dev and test server there is no problem at all. Using fiddler I see that on the production server the user agent in IE11 is set to 

User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; Trident/7.0; rv:11.0) like Gecko

I know, this is the new one added in IE11. But on the dev and test server, the user agent in fiddler looks that

User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.3; WOW64; Trident/7.0; .NET4.0E; .NET4.0C; .NET CLR 3.5.30729; .NET CLR 2.0.50727; .NET CLR 3.0.30729)

Don't know, why it differs? In the HEAD I have a 

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

Servers have different versions of IIS, but could it be a problem? On production there is a 7.5, on test 8.0 and on dev machine a 8.5 version.

If in the IE11 dev tools I change the user agent from default to e.g. IE10, then I can access the app on production server. But now I have a problem to debug, why the new user agent is a problem. I have no access to the production server, so I must test it on test or dev server, but I can't reproduce the problem.

Check your compatability view settings. Compatability view settings will set your agent string to MSIE 7.0.

In your IE, Go to Tools -> Compatability View Settings

You probably have intranet sites flagged as compatability or your dev/test servers are in the list box specifically.
