Windows SBS Standard 2011 disconnect pcs from internet


New Member
There is a Windows SBS Standard 2011 running in school. Whenever more than 10 pcs connect to internet there is someone that gets disconnected and needs to reconnect. It is problematic because there are more than 10 children in class so it is next to impossible to carry out a lesson properly.

Are there any restrictions inside this version of Windows Server that might be the reason of this?
