Not sure how I’d check that. And maybe I was unclear about what I meant by including the template info in my original post.
I only meant to imply that I created the wss site absolutely normally:
1. created web site in IIS6 inetmgr.
2. extended web site in wss admin interface (created new app pool, new content db, etc)
3. opened newly-extended site, immediately prompted for site template, picked first template (team site)
As you would expect, I then attempted to open the new site at http://www.mysite.org to verify that it worked, but I got forwarded to http://www.mysite.org/_layouts/1033/error.aspx?ErrorText=Cannot+complete+this+action.%0a%0aPlease+try+again.
To troubleshoot, I appended the default page to the base url (http://www.mysite.org/default.aspx) to see if it would load, and it did.
At this point I can get the homepage to load without appending /default.aspx once it’s cached in IE, but if I clear my IE cache I get the error again.
Beyond this weird error, whenever I attempt to upload a file to a document library, I get a 404 error at this page:
http://www.mysite.org/<doclibname>/Forms/Upload.aspx?RootFolder=&Source=http%3A%2F%2Fwww%2Emysite%2Eorg%<doclibname>%2FForms%2FAllItems%2Easpx. But if I edit that url down to http://www.mysite.org/<doclibname>/Forms/Upload.aspx, the upload page loads, and uploads are functional.
I have created many generic wss team sites and have never seen these problems before, which leads me to think that the site may be corrupted.
