Error in NetWeaver CE 7.1 Installation: Step importJavaDump with MSS 2005

Question

After a dozen unsuccessful tries to install SAP NetWeaver CE 7.1 onto a Windows platform using the Microsoft SQL Server as the backed I could use help regarding this particular error.
I receive the following error when I try to install the software with MSS as the backend:
ERROR      2008-09-29 10:40:02.319 [sixxcstepexecute.cpp:944]
FCO-00011  The step importJavaDump with step key |CE_DevSystem_App|ind|ind|ind|ind|0|0|NW_Onehost_System|ind|ind|ind|ind|2|0|NW_CreateDBandLoad|ind|ind|ind|ind|10|0|NW_Jload|ind|ind|ind|ind|11|0|importJavaDump was executed with status ERROR .
The error occurs only with MSS. I have both my Windows and MSS updates up to date. When I use MaxDB as the backend everything goes nice and smooth (even the java info dump, or whatever that command does). When I use Microsoft SQL Server as the backend this error is printed. I have tried with Microsoft SQL Server 2005 Developer Edition on both Windows 2003 Server and Windows XP Professional SP3.
The following gets printed to jload.log:

29.09.08 10:40:02 com.sap.inst.jload.Jload printErrorInformation
SEVERE: An error occured during execution. Please consult SAP note 942766 for first steps on troubleshooting the problem.
For one thing, there is no SAP note 942766 when you search for one at SAP Notes. Another thing that is particularly interesting is that the SQL JDBC driver does not get the SQL instance name, or at least does not print that to the exception message but instead leaves there two whitespaces (The connection to the named instance >>Instance name should be here<< has failed).
Any suggestions on how to get pass this error? All help would be appreciated!
Best regards,

hello,
please check and ensure that:                                                                               
- your database server is started.                                                                               
- your database instance is running and you can connect  to  it through the network interface                                                                               
- the entries in secure store contain the correct options for 
connecting to the database. (These can be checked via     configtool and this only applies to the case when JLoad is run  using secure store parameters)                                   
hope this helps
kr,
