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, 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.
