This means you're trying to copy a file that's being written to, and  
the OS thinks it has a good reason not to let you do that.  Why are  
you trying to copy the live file?  It'll get you a bunch of stale  
data and next time you copy it won't be easy to determine the  
boundary of the stuff you have already copied.

Are you trying to rotate the logs?  The best way to do that is as  

1) Rename the old log file(s).  Apache will continue to write log  
data to
    the old files, since it has open file handles on them and the OS  
is not
    fooled by something so trivial as a filename
2) Send Apache a restart (or graceful restart) by calling

    c:\path\to\httpd -k restart

    (or -k graceful).  This causes Apache to open new, empty log  
files with
    the original names, closing the old open file handles.  New log  
    will appear in the new log files without any loss.
