Hi all!
Because nobody answered my question I'll do it because meanwhile
I know the answer (Perhaps later some other user has the same
problem)
1.) It seems DCOM only works if all computers are in the same
domain. (I'm not quite sure here)
2.) You have to do the class entry at the remote machine
by hand. For instance: If your server program is
prog1.exe
and the class which implements your interface is named
kl1
search for
HKEY_CLASS_ROOT\prog1.kl1
export this entry into a file and import it at the remote machine
3.) On "Component Services" board change the default security
(the little terminal symbol).
Add "Network" to the default launch permissions.
