Thanks tw33k!

I know this thread is now 6 years old but I just wanted to drop a thank you for posting this, it got me out of a really sticky situation. I'd spent 3 full days trying to find out why I was receiving that error, trying reg hacks and browsing probably close to 100 different articles and nothing worked.

Step 6 of this guide is exactly what I needed, it fixed my problem. So thank you.

I was trying to copy from a brand new Dell 7910 Precision workstation (Xeon, 32GB, RAID5, Win7 Pro x64) to about 12 x 5-year-old Dell Vostro's with Win 7 Pro 32bit and was having nothing but trouble. This guide saved my sanity. Hopefully, it helps someone else.
