Attempting to query the AppServer Internet Adapter status page through a web browser fails.
Error: Internal commands restricted: access denied.

The Internal Administrative Command feature is not enabled by default for AIA.

The Internal Administrative Command feature is a security feature that has been added to the AIA.
To access any of the AIA status pages through the browser, this option needs to be turned on. The feature is turned off by default in Progress 9.1C and higher.
To Enable the Internal Administrative Command feature.

Through Progress Explorer:

1) Right Click on the AppServer Internet Adapter Instance in the Progress Explorer Tool.
2) Choose Properties and go select the Advanced features menu.
3) Check the box for Internal Administrative Command.

Editing the ubroker.properties file:

1) Add the following line under your AIA entry:

allowAiaCmds=1

For example:

[AIA.Aia1]
allowAiaCmds=1
controllingNameServer=NS1
logAppend=1
logFile=@{WorkPath}\Aia1.aia.log
loggingLevel=2

The settings are 1 for on and 0 for off.

Progress recommends this feature be enabled only for debugging purposes.
