Maybe if you explained what you've tried and where it failing. The following works for me with my server in place of yours:

code:

---

shell '%comspec% /c showacls.exe /s "\\maorserv\home" >c:\showacls.txt'

---

In my case I copied ShowACLS.exe to the same folder as the test script. Since I'm redirecting to file, must include the CMD interpreter.

After, it's just a matter of analyzing the output file.
