1) Open Progress Explorer
2) Connect to the appropriate Admin Service
3) Right click on the appropriate AppServer
4) Select 'Properties' from the popup menu
At this point the properties window will be displayed for the AppServer
5) Click the plus sign to the left of the 'Broker' entry
6) Click the 'Advanced Features' entry
7) Change the 'Request timeout' field to whatever value is deemed appropriate
for the application
8) Click the 'OK' button
9) Stop and restart the AppServer
