Then before surfing the web and going for extraordinary ideas, check if users you are introducing are:
1 - Memeber of RCTUniversalServerAdmins
2 - Make them administrator of local computer
3 - Make sure you have make them SIP Enabled. For this reason, after installation of Office Communications Server, in Active Directory Users, right click on the users and follow the SIP enable wizard.


Be a winner in your daily challenges
