Port nicht erzeugt

Hi,

Download ApiMonitor from http://www.rohitab.com/apimonitor (HTTP link as HTTPS usually and many times misconfigured at their part)

Only select API functions from (as shown in the screenshot )
Networking -> Windows Socket 2 -> ws2_32.dll
-> wsock32.dll

To be clear not all functions there are needed, you only need "bind" and "listen" and ("closesocket")
Also as i have no idea what DataSnap you referring to, but in some cases a "client" will use WinINet or WinHTTP, but these should not be your concern with opening ports, only if you found some missing API connections or more complex API calling like they are not coming form you application (the report will show the stack call for each API) as these client providers use the API internally and might be messing up your reports, or might no sense from first look.

After using these you should have a detailed error and response from bind and listen API call, like the socket handle is invalid as this means there was another API already destroyed the handle hence you need to expand on them or add CloseHandle to the report to track the handles.
