How do I resolve this?
Network infrastructure between the two servers.
Changes to DCE user credentials or update of the SSL certificate.
Ping the servers to ensure they are running and check your network path to rule out general network related issues.
Test the ITA/DCE server connection (in ITA selectSystem Setup > External Systems Configuration. Perform the test for both port 80 and 443 (use encryption).
Don't change the DCE server ID (IP/hostname) as part of the test because this will result in all device associations being lost.
The DCE server may be under too much stress and unable to run the necessary background jobs.
TheDCEserver may be unable to handle requests from theIT Advisorserver.
Reboot the DCE server to re-initiate the jobs.
If the server is stressed because it is monitoring too many devices, consider additional purchases.
If the connection was lost or interrupted, ITAwill collect any data it missed when the connection has been restored.
