correlation between print driver and Scan to smb...

[jmaister]

There is absolutely zero correlation right?

some guy try to pin his scanning wasnt working because print driver was updated...

SMB is port 445 or 139 (CIFS, deprecated) & TCP/IP printing can be ports 9100 and such.[emoji57]

He probably changed his PC login password...therefore an authentication failure![emoji57]

Only thing i can thank of that could link the two would be a firewall.

If the outgoing print gets blocked, and I had it before the firewall could block all communication on the device IP in both directions.
But far fetched i would think.

Knew this, thanks. i was kinda blown away too. Because I'd be rewriting the last 10 years on the job, throw out all the tricks in the book. I was certain, but just want third opinion.

Authentication wasnt the problem. I could ping from this IR ADV to my phone, and ping my phone to this IR ADV, but not to his PC.

I was thinking firewall, but he could print just not scan. It scanned to my laptop, so machine has no issue as far as I'm concerned. The first thing his IT went to look for was "Canon Print Utility" app on Win10 when they remoted in... I knew right away they dont know AT ALL. (first thing an experienced IT would ask is, IP?, login?, where is addressbook?)

I even hardwired the devices, it still couldnt find the PC. I even suggested it could be the ethernet port, and suggested to get a USB/ethernet adaptor(that could have happened, or his router fixed itself, or he changed back his router and just not owning up to it)

The claim was upon changing driver to Generic UFRII Plus, his scan stopped working. And after helping him on Sunday on my day off...the UFRII V30 is what got his scan fixed?

and! all this happend because his router was changed...

mierda de caballo!!

Check to see if the network location is set to public or private mode!!! Public mode will pretty much shut down ALL incoming ports!!! Additionally, try using hostname and if that doesn't work, use the ip address of the target computer you are scanning to.[emoji6][emoji1303]

IP didnt work.

public and private mode? I could see the share folder with my laptop, but just not able to ping even from my laptop. So it couldnt be on Public mode...

did I miss something silly? shouldnt there be a message to prompt me if something mysterious was blocking the sharing function?

machine can scan to me no problem..


*I just did a test to my pc in Public mode, i can ping it from my phone...so its something abnormal. But GOOD TIP! thx!

Just a Quick Question...is his PC domain controlled by a server? If so, you will need it to authenticate with the local machine and not the domain if possible. [emoji6][emoji1303]

its a bloody home office with ISP wifi POS router(real fibre, oooo) with two POS signal booster. I even put all the devices on LAN, no wifi.

its as basic as you can get.


RIGHT? its sooo simple. but it didnt want to be fixed that day but today, and let me have this "wtf" in my head before Monday...

LOL! OMG![emoji23][emoji38][emoji1787]...might need to check that router!!! I've had an instance or two where the router put the mfp on a "public" status and the pc on a "private" status just for effin' because!!! And only when I went into the router and set the mfp to trusted private...only then did it work!!! They were on the same bloody wired subnet ffs!!![emoji57]

I have seen it the other way around. User scans something to their computer for the first time. User does not go immediately back to computer. Protection software does not recognize the new ip address attempting to access storage drive and pops up the "Allow or Block" dialog. If the user does not respond "Allow" within the timeout period the soft automatically blocks the IP Address. Printing to that IP address is also blocked.

How was driver updated? Still no correlation between driver and SMB, but if he says "driver updated" and it was via Windows Update, check that SMB didn't get turned off during the update process. Why would it? No idea, but there have been several MS updates that did this to my clients. Beat my head against the wall until I turned the protocol back on.

If SMBv1 is ON when any Windows update is installed, the update will turn it off.

I have had a couple of situations where either a windows update or an antivirus software update turned off network discovery and file and printer sharing, which disabled scanning.
