I have changed default port 1433 to 8484 because of security reasons. For backup purpose i am using third party tool that is Symantic. After changing this default port my backup job is not running (i think the communication is not going on between symantic to MS SQL server).
The Communication is not from Backup exec only, it is not even responding to other MS SQL program. In log file error was showing:
"The job failed with the following error: Unable to attach to a resource. Make sure
that all selected resources exist and are online, and then try again."
Kindly let me know what could be the reason and how to resolve my issue.
