Network Drive Access for a3ERP
When the a3ERP data is stored on a network/shared drive (e.g. W:), the A3ERPService Windows service must run under a Windows user account that has access to that drive.
The default Local System account does not have access to mapped network drives, which will cause a login issue.
To fix this:
- Open services.msc
- Find A3ERPService, right-click → Properties
- Go to the Log On tab
- Switch from Local System account to a domain/local user account that has access to the network/shared drive (e.g. W:)
- Restart the service
