I have an employee in another city that has a folder on the server. The
server is about 30 miles away, but the problem is that for the past couple
days, when she open excel, then goes to open her documents folder, and it
takes anywhere from 4 to 5 minutes to open that folder. Anyone have any idea
on why and how to fix this problem?
