Trying to delete a directory stored on a Windows server, from on a Mac, containing files created on the Mac, getting "Directory not empty"

I am trying to delete a directory stored on a Windows 2008 R2 server, mounted on a Mac as network home (10.8.5). The directory was created by Safari and stores temporary internet files. I need to be able to delete this folder on logout from a Mac bash script.

The Terminal on Mac shows the directory as empty:

36W-FacRm-02:History lwickham$ cd /home/lwickham/Library/Caches/Metadata/Safari/History
36W-FacRm-02:History lwickham$ ls -al
total 0
drwx------ 1 lwickham CGPS\Domain Users 264 Nov 8 09:24 .
drwx------ 1 lwickham CGPS\Domain Users 264 Nov 8 09:28 ..

However, on the Windows server it has a single 0kb file that doesn't start with a "." but yet is invisible to the Mac.

E:\FacultyHome2\lwickham\Library\Caches\Metadata\Safari\History>dir
 Volume in drive E is FacultyUsers2
 Volume Serial Number is 8C17-4EF3

 Directory of E:\FacultyHome2\lwickham\Library\Caches\Metadata\Safari\History

All my attempts to delete the dir from the Mac have failed:

36W-FacRm-02:History lwickham$ rm -fr /home/lwickham/Library/Caches/Metadata/Safari/History/*
36W-FacRm-02:History lwickham$ rm -frd /home/lwickham/Library/Caches/
rm: /home/lwickham/Library/Caches//Metadata/Safari/History: Directory not empty
rm: /home/lwickham/Library/Caches//Metadata/Safari: Directory not empty
rm: /home/lwickham/Library/Caches//Metadata: Directory not empty
rm: /home/lwickham/Library/Caches/: Directory not empty

Solution 1:

Step 1, stop trying to admin a Windows server with Mac tools.

Step 2, access the Windows server through Remote Desktop, or psexec.exe, or Powershell Remoting, or something that can execute commands on the Windows server, or have the admin do it if you don't have access.

Step 3, run

C:\>rd /s /q E:\FacultyHome2\lwickham\Library\Caches\Metadata\Safari\History

That will recursively delete that directory and all files it contains. You can do it from the Mac as long as you're using a tool that remotely executes commands on the Windows machine.
