When I copy files from the Windows Vista clients to my Wondows 2000
server domain controller the copy/move is very slow. I order to copy a
15MB file I wait 23 seconds (21 seconds for "calculating time
ramaining..." and 2 seconds for the copy).
If I copy the same file on another Windows 2000/2003 server (non
domain controller) or a linux/samba share wait only 2 seconds.
On Domain Controller I don't have network errors (netstat -e).
