Did you check the accounts on the Backoffice server?
Guy on site is running window updates, apparently this pc has never been updated. He has control right now. Letting him do his thing.
/me puts on a dang helmet. Good luck!
Well, lets check back in a couple of hours. Actually windows will reset some settings when you install some updates.
Sounds like a plan.
Some of the next steps to troubleshoot are:
- open the share on the back office server from the back office server itself (this eliminates the network outside the machine)
- if above doesn't work check that the "File and Printer sharing from Microsoft Networks"-setting is enabled on the LAN interface properties.
- install and run a portscanner from one terminal to see that the ports are actually open over the network.

Didn't read al 65 posts above, so may have been mentioned or I may have missed something....
But is 802.1x being used?

802.1x ? What is that and why would it be used?
IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN. This is what i get when i google 802.1x
Is this what youre talking about? -

This is the first time im ever hearing of this so im sure the answer to that is no

I'm facing a parallel issue where a workgroup share is inaccessible, so I've been doing a lot of testing. One of things I've noticed in my tests is that when the Windows Firewall is off then port 445 closes automatically. Have you tried it with the firewalls on, but with SMB-In configured properly in the firewall settings?

I have not..

You can test the port using telnet or ssh (assuming you have either installed on a client). It will at least tell you if you can reach the port.

I dont believe i have either installed on the client side

Better to use a port scanner, for instance nmap for windows. https://nmap.org/download.html

I would use Nmap on my system, but for troubleshooting a client machine I'd rather use something lighter and faster. YMMV

Yes, but installing the complete openssh server on windows isn't light weight.
For telnet and ssh client it's better to just run putty.exe in that case.

https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.htmlPutty used to have less than helpful error messages. It looks like that has changed since the last time I used it. Either way, I'm done arguing with you.

If the terminals are Windows XP, then telnet is installed by default. In Windows 7, it can be installed, or you can get Putty Portable or something like that.

One terminal is Windows XP

Try telnetting from that terminal...
Open command prompt and
telnet 192.168.128.xxx 445
If it can't connect, it will tell you right away.

Sorry, didn't mean to start an argument for the sake of arguments. You brought up a good point which is to test with telnet which I appreciate. :thumbs_up:

That makes sense. It has been a rough week, so sorry if I read too much into your comments.

I scanned this thread quickly.
Same workgroup?
Joined domain?
Same activated account in backoffice? Same level of security?
Did something switch to the Public Network in Network & Sharing Center?
I believe I saw earlier about the firewall needing to be enabled for 445 to work. That's true AFAIR.
