when opening MS documents (word, excel, powerpoint), that are stored in a shred document list, it prompts for a username and password several times before the document opens. If we hit cancel, on the login prompt, several times it still opens the document. We are not prompted for a username and password from none MS documents and if we use any other browser but IE. So this looks like a problem between MS products. Has anyone run into this before? What was your solution?
