i am not sure what settings spybot has made but after running it my PC, although visible, it cannot be accessed over the network. firewalls are off, tcp/ip, and all other protocols and clients are installed and configured correctly. what chnages did spybot do so that i cannot access the shared folders from other PC?
Did that happen after running a scan with Spybot?If so,you could post a fixes log,so that someone could check it.Go into Spybot -> Mode -> Advanced mode -> Tools -> View Reports ->View previous reports.Look for the Fixes.yymmdd-hhmm file from when you did the scan.Open it.Copy it into the clipboard:Right click > Select all. Right click > Copy.Then you could paste it here.
Also,maybe this might help:
