Hello
I followed the notes on Andreas Marshall's TAPI and TSP FAQ site and was trying to edit my HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TapiSrv\ImagePath
to "C:\Program Files\Microsoft Visual Studio\Common\MSDev98\Bin\msdev.exe"
%SystemRoot%\System32\svchost.exe -k tapisrv according to the doc. But found the registry keys are different for Windows 7.

Any idea how to debug the same?

Using Win 7 x64.

Found the solution at last and for the record,

Use tasklist /m tapi* as administrator. Attach to the process having tapisrv.

Yes, this is working in general, but with this approach you cannot debug initializing issues on startup...

In addition it is strongly recommended to change TAPISRV to run in its own, exclusive SVCHOST process before starting to debug it in any way.
Otherwise you will stop other network services too!

Yes, that is what happening now for me. So how you do that in Win7x64??

It seems the tapi server is a dll now. So how do we spawn it its own svchost??

To debug a TSPI_lineMakeCall() issue you can use the "attach to process" approach and set a break point at the first instruction within your TSPI_lineMakeCall() code.

TAPISRV is a DLL using SVCHOST.exe since Windows 2000...

On a client OS (Vista, Win7 etc.) you can change the SvcHost mode for TAPISRV from shared mode to exclusive mode.
This has been discussed several times in this group, e.g.:
