I ran into this today –
Tagging on /_Layouts/permsetup.aspx to a site’s url brings up a list of the 3 standard groups for a site:
- one for visitors
- one for members
- one for owners

The ULS logs were a mess, and not wanting to loose a day opening a case with MS I tried PowerShell.
The solution is fairly easy.
Grab a pointer to the web in question with:
$web = get-spweb http://www.yoururl.com/sites/MainSite/subsite
You can see all the web’s properties with:
$web | fl
The 3 that we’re interested in are:
We can set these with PowerShell easily:
$web.AssociatedVisitorsGroup = $web.SiteGroups["Nameofthegroup"] $web.update()
