What is the MSSQL sa account password? (CloudVM)

Hi,

I changed my cloud VM instance from some CentOS distro to the 'Windows Server 2008 with IIS & MSSQL' one. 

When I try to add a new database via Management Studio I am getting:
Create failed for Database 'mydbname';. (Microsoft.SqlServer.Smo)
An exception occurred while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)
CREATE DATABASE permission denied in database 'master'. (.Net SqlClient Data Provider)

When I log-in to MSSQL I have found that the only account with 'sysadmin' privileges is the SA account.

SELECT
p.name AS [Name]
FROM
sys.server_principals r
INNER JOIN sys.server_role_members m ON r.principal_id = m.role_principal_id
INNER JOIN sys.server_principals p ON 
p.principal_id = m.member_principal_id 
WHERE r.type = 'R' and r.name = N'sysadmin'


So, what are the SQL log-in credentials, that are scripted, as part of the VM image? i.e. what is the SA password?

Surely, I am not the only person that has had this issue?

Thanks
