IIS HTTP error 404.11 - due to bad filename, plus signs



With URL:    http://server.name.here.com/SIERRA+FUN+FACTS.docx

Got the error message below.  First tried tinkering with mimetype (application/msword) but then decided just to change the filename

http://server.name.here.com/SIERRA-FUN-FACTS.docx

Getting rid of  +  signs solved the problem.
