It's 11:30 pm my time and still poking around the internet trying to get the scoop on this stuff - after an exhaustive search of the literature (what little there is) - here's thoughts :

1) ADsSecurity cannot set share permissions. It can only change file,folder and registry ACL's. Is this your conclusion as well ?

2) I downloaded the latest and greatest ADSI SDK and it stills states that share permissioning is not implemented "yet"

3) I guess RMTSHARE is still the best bet for permissioning shares through scripts ?

4) Permissioning registry ACL's through ADsSecurity would be a facinating topic to pursue (especially given some recent posts and that there are no (known) tools to do this job) ... thoughts ?
