File names cannot contain those characters but the user does not see them. The link they see and the underlying path can differ. Where exactly are you hitting this problem. When you reply, you will see a camera icon that allows you to insert a screenshot. That would help.

Thanks Peter. I am attaching a screen shot. We have definitely narrowed it down to a server issue. When we deliver .htm files for our external help, the external server seems to have no issues however when we deliver the same files for our internal help, our internal servers give the error you will see. Works fine for the names with no special characters.....
Hey Peter, we went in and changed the file names after reading your reply. We changed them to where the client cannot see them and it is working. We really appreciate your help.
