my configuration is :
Backup Server OS: Windows 2008 R2 Standard
Retrospect Version: 10.0.1.103 ( 64 Bit ) SQL Server OS: Windows Server 2008 R2 Enterprise
SQL Server Version: 2012 Both Servers are Domain Member Servers. Problem: I can't configure a SQL Server item, the login failed with all three possibilities. Neither the current RBU Account, nor the SQL Authentication, nor the Domain Authentication works. A RBU Account exists and is a member of the Domain Admin Group. SQL Authentication with the sa Account also fails. And neither the Domain Admin Account, nor the RBU Account, nor the SQL Service Account (The account under which the SQL Services are running) works with the Domain Authentication. All three Accounts are member of the Domain Admin Group. The inbuild Windows Firewall is down on both servers.
