Hi
If you are backing a server with have installed agent on it then please check few things to ensure
1 Click on. Backup exec icon on top left and go to install option and license keys
2 When the new windows come there it will list the license you have entered there please check carefully that it has an entry for backup exec base license and one remote agent license and when you click on next you have checked the backup exec base license and remote agent
3 If not then please import the self for remote agent license and when clicked next you would need get a box to check the license ,
4 If that remote agent license is already there then what are you exactly backing on that server like only flat file or some application like SQL ,exchange etc which will require a license key so
