Hi i followed the Guide in the Wiki how to install ms sql 2008 ( SQL Server 2008 - MediaPortal Wiki ).
So my Server is working fine, and no errors in the Log.
After this i installed a new client. But i cant realy connect to the server.
So i thing the ini file in the wiki isn´t correct to support 1.2 Beta. Isn´t it.

WOuld be great if somebody can advice how to proceed now.

I tested mith MySQL as default and everything was working. Some Server , same Host.
So defintly the database has a problem.
