hi ed,

copy the follwing file:
C:\Documents and Settings\All Users\Application Data\Symantec\Backup Exec copy the file besernum.xml to your desktop.  (for safety)

now,

delete the existing besernum.xml from C:\Documents and Settings\All Users\Application Data\Symantec\Backup Exec.

goto toos--> Install options and license keys on this media server

if it is showing any existing licenses just remove them and add the licenses keys manually means by license file ( which you have to got from symantec)  and complete the installation. this step will create new license file.

and restart the agent service on remote server after doing the above steps.

now you should be able to take backup of the server.

let me know the update

Hi girish,

I get the same error-message (0xe0009418). i've exactly done what you have described:

delete besernum.xml
delete all existing license-numers in BE, entered the licence-nummers manually
restarted the service on the remote-server

After manually reinstall of license-numbers i got this warning in the following file:
C:\Documents and Settings\All Users\Application Data\Symantec\Backup Exec\Logs\bkupinst.htm

08-13-2009,12:13:14 : WARNING: The license key changes being made do not require the services to be immediately restarted.
08-13-2009,12:13:14 : WARNING: However, until the Backup Exec services are restarted, these changes may not be accurately reflected.

restart the services of BEWS and test the job on particular server.
