Following the myriad of emails I received, here’s a link to markshareforABDE.exe as used in my blogcast about Access Based Directory Enumeration a few days ago. Many thanks to DuWayne Harrison at Microsoft in the US, the author of this tool for giving his permission to make this available. Please be aware that there is absolutely no support from PSS and all standard disclaimers apply as per resource kit tools. In other words, any use you make of this utility is entirely at your own risk.
Usage is straightforward: markshareforABDE <sharename> 0|1 [servername] where 0=off and 1=on
