Hi,
Sorry for a late posting but here is what I can tell you:
1. Run gpedit.msc and under Computer Configuration click Windows Stettings>Security Settings>Local Policies>Security Options.
Then click on accounts: LImit Local Account use of blank passowrds or something by that name (2nd or 3rd entry from the top, I believe) and click Disable. By deafult it is enabled.
2. You may also click under Local Policies on User Rights and then choose Access this computer from network and then add your login name, Authenticated Users, etc.
3. In any Folder under Tools, click Folder Options>View and scroll down and uncheck Sharing Wizzard. It's supposed to simplify sharing but can prevent some sharing options from becoming available.
4. Right Click...
