I have a working site:

    http://moss/culture/

The culture site collection has a subsite (icon show it to be a workspace) that still shows up in the Current Navigation, SharePoint Designer and the Sites and Workspaces listing.  However the link is very wrong, and I cannot access the site.

It used to be 

    http://moss/culture/par/

But the site owner did something in the Site Navigation Settings (he says) that broke the link and the /culture/ site reports the link as

    http://moss/culture/viewlst.aspx/default.aspx

Which give a 500 INTERNAL SERVER ERROR warning.  None of the content listed in the Site Hierachry treeview is accessible.  It all throws this same error regardless of the link.

I cannot access the site with any of the [administrative functions][1], but they all give the same error.

My suspicion is while trying to rename the site, the cut and paste the wrong thing into the wrong box, but I just don't know where to look next.  

**NEW INFO**
I am now a site collection admin.  I enabled the Publishing feature and I cannot access the Manage Content and Structure page.  Unknown error.

Still looking for settings to reset on the parent site.
