Disable user prompt while opening document
I am using SharePoint 2007.
I have created a e-mail workflow in designer and attached to a document library. In the e-mail content of the mail, I have a link to open the document. when the user clicks on the link to open the document, it asks for username and password. I want to disable user prompt while opening document.(the document can be a word document or excel file).
How to open the document,without getting the username and password prompt..
