Files in Network Folder Don't Appear in Windows 7

Our office copiers automatically deliver scans via SMB to a shared network folder.  These files always and consistently appear on Windows XP workstations.  On Windows 7 (x64) workstations, however, new files sometimes do not appear.  I've tried refreshing, manipulating the files on a Windows XP workstation, and other various unsuccessful tactics, but usually they simply appear after a period of time (anywhere from 30 seconds to hours later).

Was something changed in the way Windows 7 accesses network folders, and is there anything I can do to resolve this?  I have noticed that large network folders take seem to longer to load in Win7 than in XP, as though Win7 is running an extra process as they load.

FYI, we use Kaspersky Enterprise Protection suite on both WinXP and Win7 workstations.  Because the problem happens intermittently, I have been unable to test whether this might be the cause.

Thanks in advance for any assistance!

try it on a different partition than the c: drive as the c: drive permissions are different than previous versions

Sorry IanTh... should have clarified this too.  The network folder is on a volume that lives on our NetApp SAN, so no C drive to move it from.

Hi, what do you see when you map a drive on your W7 workstation and check in a cmd prompt if you can see the files?

I know there is something in Windows 7 which caches what is in the folder - saw it enabled on a NAS I worked on today ...

I am assuming here that you only have one SAN / server instead of two or more replicating data to one another as this may cause an impact ...

Thanks gerwinjansen & harryhelp... I will definitely check via command prompt whether the files are visible next time this arises.  And you are correct that we are only operating with a single SAN.

Apologies if there is a delay before I post an update - since this is an intermittent event, I don't know when I will next have the opportunity to test it.

Sorry actevolis - never found the solution at the time.  Since then, we've changed our environment sufficiently that the problem no longer seems to occur.  Could be due to new hardware, new versions of Kaspersky software, or new updates to Windows.  Unfortunately, no way to pinpoint.  Good luck, though - I know how frustrating this one can be!
