If Network Security Task Manager cannot scan a computer in the workgroup, then please deactivate "Simple File Sharing" on this workgroup-computer.

 

To deactivate the Use simple file sharing option, run Windows Explorer and click Folder Options on Tools menu.

According to the settings, this only works on the current folder. Therefore the "save viewing options for each folder" must also be deactivated.

 

Windows Vista by default disables simple file sharing be following settings in Control Panel\Network and Internet\Network and Sharing Center:

 

The security tab now appears in the Properties dialog for folders and files.

 

The following registry key is responsible for "Simple File Sharing":

HKEY_LOCAL_MACHINE\ System\CurrentControlSet\Control\LSA 

forceguest = 0 - "Simple File Sharing" not used

forceguest = 1 - "Simple File Sharing" used (Standard)

 

 

The entry can also be edited via the local security policies (Administrative Tools -> Local Security Policy -> Local Policies
-> Security Options -> Network Access: model for shared use and security model for local accounts).

 

"Simple File Sharing" is activated by default on Windows XP Professional, when the computer is added to a workgroup at the time of installation of the operating system. If the computer is directly added to a domain at the time of installation of the operating system, then "Simple File Sharing" is disabled by default.

If a computer currently in a workgroup is subsequently upgraded to a domain, then despite this, the setting "Use simple file sharing" still persists and, if unwanted, must be turned off as described above.
