To use Coins ERP+, the Coins ERP+ URL must be set as a Local Intranet site or Trusted Site. Various things in Coins ERP+ will not function at all if you are using the normal security settings for the Internet zone.
To set up Coins ERP+ as a local Intranet site:
In Internet Explorer, select Internet Options from the Tools menu.
Click the Security tab.
Click Local Intranet.
Click the Sites... button, then click the Advanced button.
If the Require server verification (https:) for all sites in this zone box is ticked, untick it.
In the Add this Web site to the zone: field, enter the URL of the COINSOA server.
Click OK on each screen.
Alternatively, you could set the Web Coins ERP+ URL to be a Trusted Site. The default security level for an Intranet site is Medium; for a Trusted Site it is Low. Both will allow cookies.
