When you attempt to save a document to a Web folder in My Network Places, you receive:
You cannot save in the folder you specified. Please choose another location.
If the program that you are using does NOT support communicating with the Microsoft OLE DB Provider for Internet publishing, you will experience this behavior.
NOTE: Many Microsoft programs, like Notepad, Wordpad, and Paint, do NOT support saving files to a Web folder.
To workaround this issue, don't save the document to a Web folder. After you save the document, copy it to a Web folder in My Network Places.
