1. Using Regedit find the key below, if it doesn't already exist, create it.

2. Create two new DWORD values of 'NoFileSharing' and 'NoPrintSharing'.

3. Modify the values of 'NoFileSharing' and 'NoPrintSharing' to either '1' sharing disabled, or '0' sharing enabled. Both setting do not have to be the same, it is possible to have one disabled and the other enabled.

4. Exit Regedit and reboot.

Registry Settings:
Key: [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\Network]
Data Type: REG_DWORD

Good luck,

Mark.
