COMPUTER ACCOUNTS
In a domain network, we create user accounts in the Active Directory (AD). Users logon to the domain using client PCs. A computer account of the client PC is to be created in the Active Directory. In other words, client PCs are to be made members of the domain and only then users can logon using the clients.
