Automatic uninstall of File/Printer sharing, Win XP
I disabled all windows XP file/print sharing on my network by downloading snetcfg_wxp.exe. You can find it in the Windows Resrouce kit or by searching online. Save this file on a network share accessible by your windows clients. Create scheduled task policy and have it run:
\\YOUR_SERVER\PATH\snetcfg_wxp.exe -c s -u MS_Server
Set the policy to run at system startup as the secure system user. I also set the "disable the action after completion" option so it only runs once on each workstation.
