Excel 2013 won't open file from network location

I have recently installed Office 2013 on several computers. Excel will not open a file from a network location. It opens the application but never opens the actual file. I have tried Word and it works okay from the same network location. If the users open Excel first and then use the Open menu option to navigate to their network file it opens fine. I have tried several options listed in previous postings but have not found anything that works for me. I have checked the event log but nothing of note is there because Excel does open it just never opens the file. Thanks.
