X301 "File and Printer Sharing for Microsoft Networks" removed at re booting (XP SP-3)

Question

Even if I run the “Network Identification Wizard” (under System properties/Computer Name) to join a Workgroup, the box ‘File and Printer Sharing for Microsoft Networks’ remains unchecked.  If I ticked it manually, it remains checked for the current session, but it is unchecked at booting.
The same occurs with the Windows Firewall (I am running that from Symantec). I switch the Windows Firewall off, but after rebooting, it appears selected again!.
This happens only with my brand new ThinkPad X301, which came with Vista. The package included a kit to convert to XP, but this installed a ‘naked’ XP, which required downloading from Lenovo and Windows about 1Gb of files (bad service, Lenovo guys!).
I wonder which “safety” issue of the X301 causes this, but how can I stop this happening? (It does not occur with any of my two old ThinkPads, also running XP SP-3 and Lenovo software).

See -> http://www.vistax64.com/vista-networking-sharing/72537-file-printer-sharing-turned-off-reboot.html  Here is the text. Re: File and Printer sharing turned off on reboot
I FOUND MY SOLUTION!!!
In my case, it was in Lenovo's "ThinkVantage Access Connections" applet. It
is additional security that is applied at the CONNECTION level.
Here is how I fixed it:
1. Double click on the ThinkVantage Access Connections applet in the
notification area.
2. Click on the MANAGE button on the toolbar
3. Select the SSID where you want File Sharing to work, and click EDIT
4. Click on the ADDITIONAL SETTINGS tab
5. Next to "Network Security", click the SETTINGS button
6. The first option in Security Settings is "Disable file and printer
sharing". UNCHECK this box. Click OK for 3 levels of dialog boxes, then
close Access Connections
Although these directions are specific to ThinkPad notebooks, the same
principle may apply for other manufacturers' connection managers.
Best of luck!
