	Not sure if it is important, but are you on the old machine,
trying to copy local files to the new machine?  Wasn't clear.

	Yeah... I had a similar problem.  Wanted to copy my Win7 cygwin
install to another machine (WinXPx64).  I also had problems with 
permission denied as an admin -- in my case, I think they were common
cygwin DLL's.  I think they were inuse -- and somehow that prevented 
them being copied.   

	In my case, I was aided by having the other machines 'C' drive
network mounted on Z:\.  I was able to copy the couple (3 actually)
of files that failed, manually, to old-machine's /tmp.  There they weren't
files that would be in use && then I could copy them across the net with
anything.  Since both machines had write access to each other's C: drive,
I copied the files from old's /tmp to the bin & lib directories where these
files lived.  Once that was done it started functioning.

	Maybe that will give you some ideas?  I was sorta in the dark as
to what was causing the failure as well, so I poked about... ;-)
