Before you can configure the IEC application, you must start the Infor ION Grid.
EC does not control the GridAgent logon. EC_ Central uses the Security context of the Grid Agent (Infor ION Grid Bootstrap - <Grid Name>) to access or modify the files contained in the CF folder. As a default the configured OS user does not have access to the network. For EC channels that require network access, a different configuration is needed.
To configure which user executes Grid and on a host, see Infor ION Grid Administration Guide.
See Microsoft Help on "Select an Account under which the service will run".
