No database connection via FDO/ODBC

Hi all,

until now I was not successful in connecting to a simple local Access database via the most recent downloadable FDO provider for ODBC connections. Generally it shouldn't be impossible, since once or twice I got a successfully established connection.

I'm successfully testing an "out of the box" MapGuide OS 1.0.0 (bundled, with Apache/PHP/Tomcat) and MapGuide Studio preview 2007, both together installed on 1. w2k Server (SP4) or 2. XP (SP1).
Previews, Layout management etc. work (mostly) fine so far, but as soon as I try to test the connection (either connection string or data source name), I permanently receive the previously mentioned error:
         "System.Net.WebException: The remote server returned an error: (559) MgFdoException. at ..."

Only the "Refine data setup" is activated, allowing me to specify the geometry columns.
The mgserver.exe process keeps the database locked, even if MapGuide Studio is shut down. The process has to be killed first, and then the lockfile *.mdl has to be deleted manually before any further access to the db is possible. Restarting or introducing "new" system databases did not help. What else?

Does anyone have any suggestions? (Or do we have a "raster-provider-like" problem? ;-)

Thanks in advance!
