I came across very strange behaviour in copy-item today. When copying a
read-only file repeatedly from the network to a local folder the first copy
works but the second copy fails, however the third copy works. The exact
same copy-item test using local C: paths works fine. Has anyone else seen
this behaviour before?

The example below shows the attribute change after the failed copy.

PS>gci \\myserver\share\testfile.exe

I'll try it out tomorrow. Just for fun, I'll also put in a start-sleep
-seconds XX on each run if I see the same failures.

I tested this with the v2 CTP, and could not reproduce. I'm sorry, but
I can't try v1 right now, but perhaps someone else can help out.

I have an idea though, and will try it with v1 within the next few days.
