Replicating Existing Accounts
In most cases, the multiplexed account—with its two sub-accounts—is used to replace a discovered service account. The sub-accounts for the multiplexed account should have exactly the same permissions and administrative rights as the original service account you are replacing. For example, if the target service has a current service account that is an Active Directory domain account with local Administrator rights, you should create two new Active Directory domain accounts with local Administrator rights. If the target service has a current service account that is a local account with Backup Operators privileges, you should create two new domain accounts with Backup Operators privileges.
