Is there a way to take a backup without Intelligent Agent? Yes of course, just fire up a DOS session on the server and issue
rman nocatalog

rman> backup database plus archivelog format '<whatever filename you
want>'

assuming you are using 9i.

To troubleshoot the Agent failure
- Read the documentation
- Search Google
Look in %ORACLE_HOME%/network/log/nmiconf.log for error messages
To restart the agent
delete all files in %ORACLE_HOME%\network\agent except ANYTHING starting with svpp
make sure the first line in %ORACLE_HOME%\network\admin\snmp_ro.ora reads
snmp.visible_services=() or snmp.visible_services=(none) and restart the service
Dbnsmpwd.bat is only part of Agent.
And yes: you do need the Agent to run jobs in OEM. It is one of it's main functions.
