Changing the AF Link account

In the default configuration, the AF Link service runs under the NETWORK SERVICE account on the Data Archive server and the NETWORK SERVICE account gets administrative access to the Data Archive element hierarchy on the PI AF server.

If you do not want to grant this access to the NETWORK SERVICE account, edit the PI AF Link Subsystem Windows service to use a dedicated domain account. The account you use must meet these requirements:

• Read and write access to the Data Archive PI\dat and PI\log directories

• Member of the AF Link to PI Windows group on the PI AF server

  Note: If you have multiple AF Link services synchronizing different Module Databases to the same PI AF database, you must run each of them under a different Windows user account.
