I have setup FTP on IIS 7.5 and can use it just fine to transfer various log files (web, smtp, firewall) EXCEPT for the current file being written to (e.g. today's log file)
Example:
website_x can transfer yesterdays log file, but not today's log file if there is somebody on the website (and IIS is therefore writing to the log file for website_x). There seems to be a "time out" and after several minutes of no activity on the website
then the log file is "released" by IIS and can be copied over (no traffic on a production website is not the idea though).
This wasn't/isn't a problem on IIS 5.0 (currently running in a live production environment).
Error encountered on 2008 R2 IIS 7.5:
FTP: 550 - The process cannot access the file because it is being used by another process.
Apparently this is a "by design" behavior per the link below.

I followed the suggestions per the link above, but it doesn't resolve. In addition, I don't necessarily think this is an FTP issue, but more of a Windows or IIS "locking" issue because I can reproduce the error trying to transfer the file using remote control
software.
Any suggestions would be appreciated. I can remote control to the server, copy the live log files to a "transfer" directory and then FTP them over, but it'd just be nice to FTP all the log files at once (not just the ones not currently being written to).
