The configuration:
The Backup/Media Server
Windows 2008 R2 Datacenter all patches applied
Symantec Backup Exec 2010 with license for SQL AND Exchange all updates applied and the server has been restarted
The target machine
Windows Server 2003 Enterprise runing Exchange 2003 Enterprise all patches ans service pack applied
The agent is installed and running.
When I tried to add the machine to a backup job with the agent running I get the error message:
An error was encountered while attempting to browse the contests of exch01.doman.local
A network connection to the server could nto be established.
If I stop the agent on the target server it show me shares on the exchange server, when I restart the agent I get the same error message.
I have edited the services file and added "ndmp 9000/tcp" to change the port of the backup exec agent.
I have uninstalled and resinstalled the agent restarted each time
I have change the log on account for the agent from system to domain\backup which is a domain admin account
I can access other servers on the network with the agent running on them to include SQL servers and plain data servers.
I have disable all firewalls and virus protection
It seems that the agent will not talk to the backup server when the agent is running.
