Network access to My Cloud extremely slow...

Just installed a 2TB My Cloud to share files, mostly PDFs, Word docs, etc., nothing like image files, media, etc., over a small office LAN.
Everybody's hooked up to a Netopia 3000 router (supplied by AT&T) & no one is accessing it over wireless.
Copied some files to it & was shocked to find them taking 30 seconds (or more) to open!
I assigned the device a static IP address & added an entry to the PC's hosts file, thinking that may speed it up & the first file I opened took about 4 seconds, but I'm now back to extrememly long (at least in computer time) times to open files.
My Cloud does have latest firmware, too.
What could be causing this & how can I speed it up?
Thanks!

2003, I believe. And I do have - I forget what it's called, but the setting under macros or security set at low, since I'm running AV software on computer.

The Office File Validation Tool causes your problem.  Save the following to an REG file and double-click to add it to your registry:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\11.0\Excel\Security\FileValidation]
"EnableOnLoad"=dword:00000000

Will try that tomorrow, when I get back to office, but what is actually going on with the office file validation tool that is causing this behavior?

It is known to make opening office files across a network painfully slow.  One of my clients had it take XLS files up to 20 minutes to open.

You are a genius, thank you!!
What would possess Microsoft to create such a tool?

Paranoia.
It's supposed to scan every Office thing for macro malware; but, really, really, really hates network shares.
