2. If more then one domain exists. you can combine the multiple domains into hierarchical tree structures.
3. The first domain created is the root domain of the first tree.
4. Another domain is the same domain tree are child domains
5. A domain immediately above another domain in the same domain tree is its parent.

2. goto computer properties check domain - soft.com
3. open the cmd type  command net accounts 
4. check role —primary
5. create same accounts -nonconforming forest root domain controller
