Symantec Installation Manager - Database Configuration - "Could not connect to server or Login Failed"

Hi,

Environment:

3 VM Mahines

1. LABDC - Domain Controllet
2. LABSQL - SQL Server 2008 Datacenter Edition
3. LABALTIRIS - Client Management Suite 7.1 SP2

I am currently on LABALTIRIS, at the Symantec Instllation Manager (SIM) interface and stuck at the Database Configuration page. My Settings are as below:

SQL Server Name: LABSQL

Windows Credintials

After I click next i received this error: "Could not connect to server LABSQL or Login Failed"

I have even tried using an SQL Server Login and am receiving the same error.

The SQL is confgured to allow remote connections and enabled on named pipes and TCP/IP

And I am using the Domain Admin account to configure and install each component.
