Can't create Datasource - Timed Out

Hi,

i want to create a datasource, but it wouldn't work correctly...

In the past i create datasources without any problems... now i install Windows7 and it will not work...

The Error:

Connection verification failed for data source: mySOurce                          java.sql.SQLException: Timed out trying to establish connection                          The root cause was that: java.sql.SQLException: Timed out trying to establish connection

I turned off my firewall - without any other result.

Any ideas ?

greetings from germany, nico
