There is a file that you need to configure to point it to your AD server
Find the AcceleratorClient.exe.Config file in the directory where the Client was installed
Near the end of the file there is a section <add key="AcceleratorServer" value= "name of your DA server" />
Put in the name of your DA server between the last quotations and then retry to open the client. It should connect to your DA server and then present you with the dropdown list of your Client databases
I'm running the client on Windows 7 and have no issues
I checked the config-file. It already has the correct entry in it. Same message. I assume it has something to do with firewall, grouppolicies, or some other disturbance of the os..
