I had here tried a number of things to fix the issue that I am facing on Vista 64bit. I am not able to get proper working settings. I had kept the network as private. There is a password for those who want to access it. The network discovery service is kept on. File sharing is also active. I had disabled firewall to avoid any blockage. Later on I was working with DNS server. I had not done this settings before. I am facing issue with Active Directory. I got the error on the screen while configuration. Any idea what it is actually.
