XP Pro SP3 fully patched, T60 notebook with recent install of the OS, all drivers present and updated.
Local home network
In my Local area connection properties, the "File and print sharing for Microsoft Networks" tick box is unchecked on every reboot, I must check it every time after a reboot.
I have updated my network driver to the latest available with no change, looks like all the other needed protocols are installed and remain checked.
Windows firewall is turned off, I even disabled it in Services, no change.
Maybe something in group policy?
Any suggestions are welcomed, I have never seen this behavior before.
