I have one user who's computer takes forever to open network Powerpoint files. They will hang on the downloading for several minutes. His computer is similar to everyone Else's in our environment and they all open the same file quickly. We are running Office 2010 on all computers. I have optimized Windows for performance. I have used MSCONFIG to make sure nothing is running in the background. He is on a GIG port on my switch. I uninstalled and reinstalled Office. I deleted his profile and added him again. I even read that you need to have a printer installed so I checked and he does. I installed Powerpoint 2003 and now 97-2003 files open quickly using the older version but more recent files are still very slow. I have tried all the usual solutions but nothing seems to work, any ideas?
