We are waiting for client to confirm. Here is the message from client

"Thanks for forwarding the links. The networks team found the issue. They will be working on it today, and hopefully, the issue will be resolved today."

Interesting. Did disabling the firewall then resolve the issue. I can't tell from your post.

I did a webex with client and these are my observations. I created a new "Test227" folder on FTP server which client could not access so I renamed it to "227Test" and client was able to access. Basically any folder ending with "227" is not accesible from client network.

I also found that using Windows Explorer , Firefox and IE client was able to access "227" folder but from command prompt, custom scripts and FTP clients (Filezilla, WS_FTP) he was not able to access "227" - It seems they were able to access "227" folder until 5/7/09.

It seems like it may be firewall issue at client end. This is what I found in the web

Iwan,

Actually I need to apologize. In my scenario it was the firewall, but it was not really renaming the files.

Check with your firewall team and ask if they are running checkpoint ngx. If they are, have them check if smartdefense application intelligence "FTP" "FTP Bounce" is checked off.

If it is, have them set it to monitor only.

SmartDefense somehow corresponds 227 strictly to passive mode.

Note- this is NOT a normal operation of firewalls. Normally, firewalls do not do content inspection at layer 5+, they usually operate at layers 3/4.

Again I apologize.

Anything in the FTP logs? Error codes?

Windows 2008 FTP server (IIS 7.0): the system cannot find the file specified error

We recently migrated FTP to Windows 2008 (IIS7). One client reported that they get "the system cannot find the file specified" when they try to access one folder.

They are not having issues accessing any other olders. We tested using client account and it just works fine. Our FTP directory as follows

A (Folder)

100 (sub folder)
101 (sub folder)
102 (sub folder)
103 (sub folder)
104 (sub folder)
226 (sub folder)
227 (sub folder)
228 (sub folder)
229 (sub folder)
230(sub folder)

B (Folder)

100 (sub folder)
101 (sub folder)
102 (sub folder)
103 (sub folder)
104 (sub folder)
226 (sub folder)
227 (sub folder)
228 (sub folder)
229 (sub folder)
230(sub folder)

They only get this error when they access "A/227" and "B/227"

Any suggestions how this can be resolved. Since it is working for other users and also working for me using same client credentials I believe the issue could be on client machine.
