I am a Domain Admin and this even happens to me if I login at the sites. It is not a permissions issue as I can transfer any file I wish to the same spot except for KiX32.exe and WKiX32.exe. I really think it has something to do with the "The redirector has timed out a request to 'myserver'" message I get. I just tried transferring KiX32.exe in .zip form and it worked flawlessly... this is very weird.
