Possible Solutions:
1. http://www.veritas.com/docs/000005461

2. Verify the account used for the restore is using the User Principle Name (UPN) instead of the User Logon Name.

UPN Example: user@domain.local
User Logon Name example: domain\user

To verify the account is using the UPN

  1. Go to Network - Logon Accounts from within Backup Exec
  2. Select the account being used for the restore and click Edit
  3. In the User name box verify the account is listed as user@domain. If it is not, change the User name to the UPN.
  4. In the restore job, under Resource Credentials verify the Logon account is set to use the account with the User Name of the UPN.
