Hi to all!

It´s the first time i have set up a Blackberry Enterprise Express Server. The version is 5.0.0.x running on SBS 2008.
It seems, that not everything is working, i have several errors in the logs, which are driving me mad!

The worst one ist this MDS Error:

<MDS-CS_BLOOMSERVER_MDS-CS_1>:<DEBUG>:<LAYER = SCM, Admin. Task started;>
<2010-10-05 00:02:26.958 MESZ>:[32]:<MDS-CS_BLOOMSERVER_MDS-CS_1>:<DEBUG>:<LAYER = SCM, General Error connecting to the database.: com.microsoft.sqlserver.jdbc.SQLServerException: Es konnte keine Verbindung mit der benannten Instanz "" hergestellt werden.

<2010-10-05 00:02:26.958 MESZ>:[38]:<MDS-CS_BLOOMSERVER_MDS-CS_1>:<DEBUG>:<LAYER = SCM, Admin. Task- Configuration data>

I have double-checked the database-rights and have no errors in the database connection (tested in the blackberry confguration tool.)

I have no idea where the problem is, does somebody know this error?
BTW: When i had the server freshly installed, the database connection was set to dynamic and i had problems to open the admin interface. after setting it to Port 1433 and also setting the port in the blackberry configuration tool, it worked! Maybe changing the Port has caused the MDS error?
