Just completed migrating an old NT4 FTP server to 2003. It appears that all works fine with manual uploads, but more than one of our clients has attempted to upload with an automated process - scripted or client based and had the problem where they get an access denied error message after starting the upload. In checking the log files, it appears that a single file was attempted to be uploaded many times. The strange thing about it is that the time stamp in the log of each of these duplicate uploads has the exact same time.
I am suspecting that the the access denied error message is due to the file being overwritten by the multiple uploads of the same file name. The ftp account does not have the ability to delete files only upload.
I cannot figure out why the file is being uploaded several (sometimes over 50 times) with the exact same name at the exact same time - right down to the second.
Software/Hardware used: Windows Server 2003 R2 SP2 64 bit, HP Proliant BL20P G4
