Please ensure all rights are given as per link below

Also please go to network log on account and ensure system log on account is selected with domain\username and correct password

& then check if you are able to expan the selection



Don't forget to give a "Thumbs Up" or Mark as "Solution" if someones advice has helped you.

all rights are fine as its the same domain admin account i use to backup the other servers. system log account is selected and username and password are correct.

any other ideas?

Is this server's data different from the others ? Would you pls explicitly verify if the Backup Exec account indeed has the permissions to back up this server ...And, try adding the server using IP address / FQDN under User-Defined Selections...Right-click on the server name & choose to establish trust..Check if you are able to expand the backup selection then or not.

The account does have permissions to buckup the server!

I have tried to right click on the resource to go into the 'manage user defined selections' but get the following error:

Pls try to re-register a dll using this KB -

Post this, re-try to establish a trust...If you get the same error, run a repair install of Backup Exec.
