SYMPTOMS
When you try to access an application on a Microsoft Intelligent Application Gateway (IAG) portal, you receive an error message that access is denied. Additionally, a Warning event that resembles the following is logged in the Security log of the IAG event monitor:
Severity: Warning
Time: DATETIME
ID: ID NUMBER
Type: Unrecognized Application
Category: Security
Trunk: PORTAL NAME
Description: Request failed, wrong configuration of the application server, port, or path. Trunk: PORTALNAME; Secure=1; URL: https://Application_Server/WebDirectory/IISWeb.dll; Source IP: IP ADDRESS
CAUSE
This issue occurs when IAG cannot recognize the application on the secure (HTTPS) portal that is named “PORTAL NAME”. This issue may be caused by the incorrect configuration of the application server name, of the port, or of the path.
RESOLUTION
To resolve this issue, verify the configuration of the application servers in the application properties. To do this, follow these steps:
  1. Open IAG Configuration.
  2. Expand Services, expand HTTPS Connections, and then click the trunk that is reported in the Warning event.
  3. Click the application in the Applications list, and then click Edit.
  4. Click the Web Servers tab.
  5. Make sure that the IP address or the fully qualified domain name (FQDN) of the Web server that is reported in the Warning event is in Address list.
  6. Make sure that the port that is reported in the Warning event is in the HTTP Ports list or in the HTTPS Ports list.
  7. Make sure that the path or the paths that are reported in the Warning event are in the Paths list.
  8. Make sure that the FQDNs and the hostnames can resolve to an IP address.

    Note You can use the NSLOOKUP command or the PING command at a command prompt to test whether the FQDNs and the hostnames can resolve to an IP address.
  9. Click OK.
  10. On the File menu, click Activate.
  11. In the Configuration pop-up window, click Activate.
