Hello , I faced this problem one week ago and tried to solve it by changing the lan settings in the browser but it was in vain , also i tried another solution regarding the registry but also it didn't work .. Eventually , by analyzing this problem i found that it is related to the user profile .. therefore , I deleted my user profile and create a new profile and now every thing is going right .
I hope it will be helpful for all .
thanks,
Inas
