Fast workaround:
Restart the Cognos BI server or service.

Go to administrative tools on the Windows 2008 server.
Go to services
Find IBM Cognos in the list
Right click and select Restart
Wait 5 minutes and try again

Possible Solution:

In a multi server installation of Cognos BI
Ensure that Content Manager is active on all servers where it is installed.

Go into Cognos Configuration
Go to IBM Cognos Services
Set TRUE after Content Manager service enabled?
Save
exit and restart the Cognos Bi service.

Repeat on all servers.

The primary dispatcher used in a Cognos BI multi server solution must be on a Cognos BI server where the application layer is installed.
