The three FaxMaker services as seen in the Windows Services panel.
FaxMaker uses service accounts to carry out the functions of the software. A domain user account enables the service to take full advantage of the service security features of Windows and Microsoft Active Directory Domain Services. The service grants specific local and network access to the account, or to any groups of which the account is a member.
The overview diagram of the product which includes the services and some of their functions is shown below:
Due to all the external entities that FaxMaker interacts with, it is recommended (although not mandatory) that the service accounts used for FaxMaker are Domain Admin accounts.
Setting up these accounts is outside the scope of FaxMaker support, but the article about the requirements for the service account contains the necessary information.
