Thank you both for your information.
Mclemson - let me clairify a little better, I am at the platform installation phase and it is the connection to the off box SQL server that is failing, thus causing the installation of the platform to fail. I set a trace on the sql server to watch the log activity as the platform installation progressed and have identified the following based on the sql server log ( the error is below).
"Cannot open database "Symantec_CMDB" requested by the login. The login failed.
"Login failed for user 'domain\Altiris_acct'. Reason: Failed to open the explicitly specified database [Client: <IP of NS>]"
to clairfy - I am using the SIM to create a new database (Symantec_CMDB) NOT connect to existing.
