Hi
To prevent this error it is necessary to determine which IP the Web Server was set to use, and use that in Cognos Configuration instead of localhost.
To find the IP that the Web Server is set to use Internet Information Services (IIS):
Open IIS.
Right-click Default Web Site and select Properties.
Check the IP address specified on the Web Site tab.
In Cognos Configuration, select Environment and enter this IP address into each URI that is displayed in the right-hand panel.
