If that's the case then there's a design flaw with that implementation I found my original webui.zip in "%appdata%\roaming\utorrent" instead of "%appdata\local\utorrent" - I simply copied it back over to where it's supposed to be, and the webui works again. I haven't upgraded my home server to 3.1.2 yet, will do so now to see if it exhibits the same behavior. Just realized, remote uTorrent server is Windows Server 2008 x64, home server is Windows Server 2003 x64. Going to %appdata% at home, there is no "Roaming" "Local" or "LocalLow" - it's JUST it's own directory. OK, @ home, upgrading to 3.1.2, on Server 2003, the webui stayed enabled, and my previously set username/password were retained this time, however, the "Alternative listening port" was disabled, where as I had it enabled previously. When I installed uTorrent to my Server 2008 box, I just typed in %appdata%, and found the uTorrent folder, and dropped the webui.zip file into it. Didn't realize I was in roaming instead of local. Any way to test and verify this?
