Before we start making any configuration changes to the Web Services for Microsoft Dynamics GP, there is a couple of decisions to me made:
- Decide which port is to be used. Web Services by default installs on port 48620; to enable a secure connection a different port must be used. You can use any available port; to keep clear of any other ports being used, the port I am using for this series is 48666.
- Create an externally accessible hostname with associated certificate; I am not covering this area in this series, but Microsoft’s Dan Peltier did a recent post titled “DNS Overview for External Workflow 2.0 Email Notification Approval”.
Finally, make sure to backup all configuration files before any changes are made to allow for a rollback if necessary.
