Summary
This article provides suggestions for troubleshooting error return code 11002 (CM_ERR_TRY_AGAIN).
Resolution
There is typically a hostname resolution problem:
- Make sure that the machines involved in the backup (master server, device server, client, and GUI), can ping each other by hostname.
- Check DNS/WINS for fully qualified/short name errors for the hostnames.
- Add entries in the local hosts file on the servers as a troubleshooting step.
- Scan the machines into the Backup Express enterprise by IP address rather than hostname.
- If you are using both WINS and DNS for name resolution of the machine, check for incompatibility between WINS and DNS.
