I've been tinkering with this for days now and I can't seem to figure out the problem. I know there were problems < 3.0.8 with robocopy and a few other programs, but even after upgrading, I'm still have a similiar issue with related errors. I'm running Samba 3.0.10 on FreeBSD pointed to an NT4 DC. I'm trying to copy files over to one of it's shares via robocopy from a few other NT4/W2K/XP machines. From the client machines, I can map drives, login to the server, copy, move, overwrite and delete files just fine from within explorer on both mapped drives and just using unc paths. I can't get robocopy to work sometimes without spitting out this: 100% Older 4617 1.gif ERROR 5 (0x00000005) Copying File D:\Inetpub\global\images\ven\norm\1.gif Access is denied. Waiting 30 seconds... Retrying... Now here's the crazy part. These errors only occur if the remote file is newer than source. The minute I tell robocopy to exclude files that are older on the source than on the destination, the newer source files copy over to the destination just fine. This fails: robocopy "D:\Inetpub\global\images\ven\norm" "\\x.x.x.x\Inetpub\global\images\ven\norm" /S While this works: robocopy "D:\Inetpub\global\images\ven\norm" "\\x.x.x.x\Inetpub\global\images\ven\norm" /S /XO This initially led me to believe that this was a source permissions problem, but for testing, I'm running the robocopy as the local admin which has full permissions on the source files and directories. Like I said, I can do the required file actions manually via explorer, just not within robocopy. To make matters worse, when these errors occur, I have nothing in my log.smbd, or loc.user files, nor anything in messages, auth, or ipf logs. At this point, I'm way stumped. Any ideas?
