Hello, I installed W2K3 server on machine and all works fine. I have 2 network adapters. One for local network and one for internet. I use Winroute for NAT and mail administration. All works fine. Next I want install Active Directory. I use AD wizard which install DNS and AD. All works fine but in about 4 hours (sometime in later sometime sooner) my internet conection does not work. I must change IP adres of network adapter for internet connection and then change it back and all works fine. In protocols I see in SYSTEM folder this errors : 8015, 2505, 8035. Can someone PLEASE help me?
