Backup exec won't backup more than one share CIFS netapp

Hi.

I’m Using Backup exec  2012, and backup share (CIFS) on  netapp without NDMP, and ‘I’m facing a problem since one week …

the problem is:

With several shares selected, and when run a backup job, after backing up the 1st share Backup exec give an error(Backup failed), and job stop on error
I made several teste with several jobs (allways the 1st share its ok and the second share give error) .

On backup job (edit/creation) I can browse all shares (the  user have admin rights on backup server  and NetApp filer).

The detail information on the job log (for first share) the one working well:

Set type               : Backup
Set status             : Completed
Set description        : ap2fssia01 Backup 00168-Incremental
Resource name          : \\server\1stshare
Logon account          : SGGP Backup Administrator
Encryption used        : None
Agent used                     : No
Advanced Open File Option used : Yes

The detail information on the job log  (for 2nd and followings shares),

Set type               : Backup
Set status             : Completed
Set description        :
Resource name          : \\server\2ndShare
Logon account          : SGGP Backup Administrator
Encryption used        : None
Error                  : e000fe29 - Authentication failed on connection to the server. Make sure that the user account has the appropriate permissions and that the password was typed correctly.
Agent used                     : Yes
Advanced Open File Option used : Yes
 

 The only difference is that Backup exec  for first share “Agent used = no”  that’s correct we are using CIFS in Netapp without DNMP.

The second and next shares backup exec  says “Agent used= Yes”, and abort the bakup job.

The error : Access is denied to Remote Agent.  Check the login account for the specified device

 any help will be appreciated
