I even tried to change it to Automatic and checked all the settings but no vail. Please help me out. Is that because PDC is disabling the IAS service? or Group Policy is shutting it down? i got not idea why, everytime i log in to BDC i need to start the IAS services and also the IAS application service. Need help since it going to be used by our client using VPN client.
