Definition of Fax Service in Network Encyclopedia.
What is Fax Service?
Fax Service is a service in Microsoft Windows that lets you administer fax devices on both a local machine and over the network. Besides allowing users to send and receive faxes both locally and over the network, Fax Service includes extensive document archiving and logging options for billing and troubleshooting purposes.

How it works
Fax Service is integrated as a snap-in within the Microsoft Management Console (MMC). Prior to configuring a fax device, choose Programs, Administrative Tools, and Computer Management from the Start menu. In Computer Management, open the Services And Applications folder and click on Services. Then right-click on Fax Service in the right pane of Computer Management and choose Start from the context menu to start the Fax Service. To configure a fax device, access its property sheet. Then configure its Transmitting Station Identifier (TSID), which identifies the location that transmits the fax, and the Receiving Station Identifier (CSID), which identifies the line that receives the fax. The TSID and CSID are usually the telephone number of the fax line. TSID and CSID are required on all faxes in some locales.
Sending and receiving fax with Windows 10
Windows 10 includes “fax and scan” program which turns the computer into a direct replacement of a hardcopy fax machine.
To send (or receive) a fax from a Windows 10 Computer using Windows Fax and Scan you’ll need the following:
- A computer running Windows 10
- Modem or Fax Board on the computer (the majority of computers that have a telephone line connection have this ability)
- A land-line phone line. The phone line should not be a VoIP phone connection as VoIP signals usually scramble a fax signal
- A document to send
When using Windows Fax and Scan as a fax machine, the computer needs always to be turned on and connected to the phone line to receive a fax.
As well, the computer will not be able to use your internet connection to send and receive faxes – only the phone connection.

Windows Fax and Scan is quick to configure.
