Scanned files not showing up in shared folder

We have several copiers at our office that are used for scanning documents to .pdf files, among other things. Last week we added yet another one and I configured the copier to scan the files to a department shared folder just like I’ve done many times before. When testing the new setup I would see the new scanned files in the folder from my machine, but the users in the department that it was set up for only saw an empty folder. Several minutes went by and finally one user could see the file, but the other four or so still could not. So after doing some digging I found several forum posts and Microsoft articles on the subject and a registry hack that did the trick for me. You can find the article from Microsoft here. To sum up the fix, here is what is required. Change the DWORD value for the following registry keys to 0 (zero).

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Lanmanworkstation\
Parameters\FileInfoCacheLifetime

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Lanmanworkstation\
Parameters\FileNotFoundCacheLifetime

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Lanmanworkstation\
Parameters\DirectoryCacheLifetime

And thats all there is to it.
