Error 3709 when connecting thru ADODB.connection to SQL Server 2008 in Excel

Question

I'm trying to open a recordset on a SQL Server in Excel using the below code, but get a 3709 - The connection cannot be used to perform this operation. It is either closed or invalid in this context. error. Where am I going wrong?:

EDIT:

It is now working, i'll update the code below:

'Declare variables'
    Set objMyConn = New ADODB.Connection
    Set objMyRecordset = New ADODB.Recordset
    Dim strSQL As String

'Open Connection'
    objMyConn.ConnectionString = "Driver={SQL Server};Server=SERVER\SERVER; Database=we_ci_db; Trusted_Connection=Yes"
    objMyConn.Open

'Set and Excecute SQL Command'
    strSQL = "select * from tblUsers"

'Open Recordset'
    Set objMyRecordset.ActiveConnection = objMyConn
    objMyRecordset.Open strSQL

'Copy Data to Excel'
    ActiveSheet.Range("A1").CopyFromRecordset (objMyRecordset)

Solution

Remou pointed me in the direction of an alternative Connection String, but I still got the same results. I googled around for a bit and came up with another SO Question LINK with a different implementation, which resulted in:

'Declare variables'
    Set objMyConn = New ADODB.Connection
    Set objMyRecordset = New ADODB.Recordset
    Dim strSQL As String

'Open Connection'
    objMyConn.ConnectionString = "Driver={SQL Server};Server=SERVER\SERVER; Database=we_ci_db; Trusted_Connection=Yes"
    objMyConn.Open

'Set and Excecute SQL Command'
    strSQL = "select * from tblUsers"

'Open Recordset'
    Set objMyRecordset.ActiveConnection = objMyConn
    objMyRecordset.Open strSQL

'Copy Data to Excel'
    ActiveSheet.Range("A1").CopyFromRecordset (objMyRecordset)
