cannot copy file with name that end with 227 (eg 20080211110227 normal txt file), get 550 file not found

i have an ftp server on my network, that holds CDR's for SMS.
every 10 mins the system close a cdr file and name it YYYYMMDDHHMMSS.
when we try to get the files using normal ftp client (cmd, totalcmd etc.) we get the error:
550 2008021111022_ :the system cannot find the file specified  
(it removes the last 7 and place _ instead).
it happen only with this file name. other files that end with 27 are transfered correctly.

any ideas?

perhaps the file is in use when you attempted to download?

Try restart IIS and have another go.

it happen when the file is closed.
it's one file out of many...
iis reset won't help

I was curious to see if you were able to resolve this issue?  We are running into the exact same issue while trying to trasfer files from a Unix platform to our AS400 via FTP.

Had the other end ensure that the file name not end in 227 and this resolved the issue.
