Thanks for the reply. I'm using Windows Server 2003 on both ends so the ftp software is current. I have checked the Active Mode flag and that helped but it did not cure the problem. If I turn off date based synchronization then new files won't be uploaded unless their file size is different.

I'm having problems synchronizing. I'm using date difference, time zone difference is checked. It will synchronize 100% and then if I synchronize again it will send around 50% of the files back up and nothing has changed. Any ideas?
