Please take note whne you try to push down the client computer requirements for SharePoint 2013 with IE 10 + Windows 7!
I bumped into this error when trying to set target audience for SharePoint Publishing Navigation.
This issue happened only on IE 10, if i used IE9, this error will not happen.
After several rounds of testing, it is confirmed that the IE 10 Browser Mode “IE 10” that cause this issue. I’m shocked that IE 10 default browser mode does not support SharePoint 2010.
In order to avoid this error, you’ve got to hit F12 “Developer Tool”, look at the toolbar and change the Browser Mode to “IE 10 Compatibility View“. Then this error will be gone.
Internet Explorer provides seamless authentication using Windows Account to only trusted site or local intranet site. To avoid unnecessary prompt for re-login to SharePoint Site. Simply add your SharePoint site URL as Intranet site or Trusted Site.
- Open Internet Explorer, Click Tool > Options (or Alt + T + O)
- Click to Security tab
- Click on Local Intranet / Trusted Site (either one)
- Uncheck “Require Server verification (https) for all sites in this zone”
- Enter the URL and click Add
Close your browser and open again. Your Windows Login should be automatically authenticated to SharePoint site now.
For SharePoint with seperate domain
You may want to add the same login domain user account in the Active Directory of the domain where your SharePoint is hosted. For example, if your windows login is DomainA\mylogin, create a domain user account in Domain B Active Directory.
