I just started MY MCSE. I have a doubt regarding configuring Domain Controller. The name which we specify as a DNS name is what? Is this the name of our own website or something else. I just confused by the word DOMAIN. Whenever I hear the word DOMAIN, it occurs to my mind that it is the name of space reserved on internet, which is used for creating the websites, etc., (OR) DNS name is just a local database name which we create is Server? Is this no way related to internet? Please help me in this matter, if both my conclusions were wrong, please tell me what's right.
