SQL Server does not exist or access denied

Hello,

I am having an issue with MDT 2012 with the database.  It wont auto name the computers for me, i have a suspicion that it is my customsettings.ini, and possibley i have to put credentials in the sql part or something.

I use the MAC to identify the computers only.

MDT and the SQL are on the same server

Errors:

SQL Server doe not exist or access denied

Unable to establish database connection using [CSETTINGS] properties.

Here is my customsettings.ini (the SQL bit only):

[CSettings]

SQLServer=servername

Database=MDTDB

Netlib=DBNMPNTW

Table=ComputerSettings

Parameters=UUID,AssetTag,SerialNumber,MacAddress

The database wizard generated these settings automatically.

Any advice anyone

Tahnks.
