SMB Communication Problem

[blackcat4866]

This one Win7 PC is starting to really irritate me.

This all started after an office move.
The first thing that I noticed is that NetScan was able to see the PC, but was only able confirm ports 21 and 25, not 139 or 445.
When I tried to ping this same PC from my laptop it times out every time.
Then from the RUN screen I attempted to access the share folder. Naturally it fails "Unable to connect ... "
We changed cables, changed switch ports, and checked file sharing and scan folder share settings. As far as I can tell, it's all set correctly (nothing different).
The customer has changed internet providers, but retains the same basic IP scheme as before.
All other functions of this Win7 PC seem to work normally.
Up until now the enduser has been able to scan to their SMB folder via port 445 (192.168.1.100:445). The enduser can access the other scan folders from the RUN screen, but noone can access the folder from the one Win7 PC.


Do you have any idea how port 139 and 445 would unexpectedly close? What should I be looking at?
I don't think it really matters, but the MFP is a Copystar CS-2560.

Re: SMB Communication Problem

Here are some things to check that you did not list.

1 username and password of win7 machine.
2 workgroup/homegroup
3 is the network connection on the win7 set for home/office/public (default on new connection to internet is public which blocks the smb and network discovery and other nice settings.)

Re: SMB Communication Problem

I see no mention of windows firewall or anti virus software.

that's what blocks ports

Re: SMB Communication Problem

Hey thanks. I'll take a look at those things. =^..^=

Re: SMB Communication Problem

Yeah I would put money on the LAN connection being on public and closing all the ports on the firewall

Re: SMB Communication Problem

I had similar issue. Customer moved and upgraded from xp to win7. On win7 enable file sharing on network settings. If anti virus, temporarily disable and try to scan. Ive had to also give user a password on win7 to work.

Re: SMB Communication Problem

As is more often than not, when connecting a Windows Vista / 7 computer to a network that isn't recognised already, Windows prompts the users to select the type of network that the computer is attached to.

In some cases, there was also a MS Patch for Windows 2008 and Windows 7 which resolved an issue where the PC would change itself from being connected to a "Work" Domain to a "Public" network without warning. This would then close the firewall up and stop other services from running correctly.

As already mentioned, check the firewall and the network type from the "Network and Sharing Centre".

If all else fails, shoot the computer in the face with the Grand Daddy of all bricks and call it a day...

Re: SMB Communication Problem

Had a customer that had an scan to SMB that "just quit" working....come to find out, it was antivirus software...can't remember if it was AVG or Norton...anyway, I turned it off completely, tested ok and then I incrementally turned features back on to find out what the issue was...It was a port on the receiving computer that was being blocked and ignoring any incoming communication attempts. So I had to make an exception for the MFP that the scanned file was being sent from. Unblocked and allowed TCP and UDP communications from the MFP IP address.

Everything worked ok after that!

Re: SMB Communication Problem

I had one install that it didn't matter what the hell I did, it wouldn't work; one PC with a wireless connection way in the back when I had the whole office scanning at 5-8 minutes setup time per seat; took an hour on this rebel..

I got it to "work", and here's my secret:
The receptionist never turned off her PC, so I setup a folder share tucked in 2 sub-directories deep under the Public folder;
I pointed the MFP to this path for scanning to such and such PC in the address book; I put a desktop shortcut to that share on the wireless PC's desktop, named it "Scans" and said "There you go.." 1 year later, and nobody has caught that lol

Re: SMB Communication Problem

Customers IT has resolved, but never told me what it took. =^..^=

Re: SMB Communication Problem

Shhhhhhhhhh....... don't tell anybody cause we want to keep it secret but I have the solution:

Scan-to-FTP

Works ALWAYS. Works after any update from MS, works when permissions are changed, works when authentication is changed, works when IT plays around in the server etc. etc. Just take care that the IP-Address of the FTP server is static.

Just last Friday there was another such issue at one of my customers. SMB messed up, provider changed so no SMB scan and no scan-e-mail. IT was not able or willing to fix this since 3 days. I went there to bring toner and was welcomed with "YOUR MACHINE IS NOT SCANNING AGAIN!!!!!" So I told the angry ladies please don't inform your IT that I'm here, tell them that suddenly scanning worked again and that there is no need for them anymore to take action and......., give me 5 minutes per workstation, than everything will be fine.

So I installed Quick 'n Easy FTP lite server locally on each workstation, configured the firewall accordingly and that's it. After a little more than half an hour 6 workstations could scan and 6 happy faces where looking at me.

I want to fully embrace ftp, but what do you do about laptops that have to stay dynamic (and no I'm not comfortable toying with router config without their IT)

and does your ftp software support multiple folders to one PC (i.e. a server)? I know Konica's ftp utility did not

On newer Konica Minolta devices, you can actaully use the DNS Name of the PC instead of the IP address when setting up Scan to FTP. Once upon a time ago, you could only enter in an IP address for FTP destinations.

As for multiple folders, all FTP software supports this, you just need to make sure that you enter in your settings into the MFD correctly. As with all FTP servers, you must first set a Home Folder in which the FTP session will start from. This root folder can be thought of as being similar to the root of the system drive, but FTP Home folder will be a folder that resides with in the system drive (or another drive / partition).

From there you can have many folders which you can scan to, you just simply put the name of the folder into the destination when entering in the One-Touch on the machine. If you simply want to scan to the root of the Home Folder, all you need to enter into the destination is a / without anything else.

Just figured this out in my Fiery class today when using the KM FTP utility. My problem is I had been following the konica minolta documentation until today. In the FTP utility just add the drive itself as the path and no other folder/subfolder whether it is "C" drive or drive letter for a usb drive. Then for example if you want to scan to C:\FTP then in the one touch just put "FTP" as the file path. Works with anonymous and no password if you like. You could create more one touches to send to other folders and sub folders under your drive path. So yes you can scan to multiple locations as long as it is within the same logical drive.

It is also very useful to use it for flashing firmware for pretty much any konica minolta copier since 2004 using ISW via ftp. Did it in class today on a C353 and a C284. Easy configuration and select download and it does the whole process unintended. Useful if you keep a copy of ftp utility installed on your laptop and then have a collection of firmware files. Can just hook laptop directly to the copier or use a switch and hook up to a dozen or more copiers and flash them all at once.
