Windows XP Network Error 71 after last firmware upgrade

Post by funny_ambience »

Hi Everyone,
After recent fimware upgrade I have a problem connecting to NAS server. The error message is as follows:

Code: Select all

System error 71.
An error occured while reconnecting V: to \\NAS_server\shared_folder
Microsoft Windows Network: No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept.
This connection has not been restored.
The client system is Windows XP SP1. NAS server model TVS-1282, QTS 5.0.1.2248
Server log (/var/log/log.smbd) shows NT_STATUS_ACCESS_DENIED error.
Until upgrade it worked fine.

Hi,
I have the same problem. It was working well before. After a recent firmware upgrade I have this problem also.
NAS: TS-230, QTS-5.0.1.2248
Client: Windows Small Business Server 2003 SP2

However under a Win10 client it works fine.

Probably SMB1 was disabled, check the forum search for plenty of these threads already.....or just the user manual on how to enable SMB1 again

Time to update client?
Such an old OS and a very new NAS OS could cause some issues.
In addition: as far as I remember latest service pack for XP was SP3...

Windows xp uses smb1. With the new firmware, smb1 is disabled. That's why you're having this problem.
You can open it as below and solve the problem.
Control Panel > Network & File Services > Win/Mac/NFS/WebDAV > Microsoft Networking > Advanced Options > Lowest SMB version: SMB 2 -> SMB 1

Be careful, SMB1 contains vulnerability. But if you are using windows xp, you already have many vulnerabilities.

I installed the latest firmware for the TS-639 and my XP cannot connect.

I cannot find the SMB option in the QNAP control panel. Help refers to it, but I cannot find it.

What is the command line option to restore SMB1 in putty?

You can check if SMB1 is enabled in

Code: Select all

[~] # cat /etc/config/smb.conf
[global]
...
min protocol = LANMAN1
...
The "LANMAN1" is the synonym for SMBv1.

TS-639 4.2.6 Build 20221028 with Windows XP

I seem to have similar problems with SMB2.

But I did SMB2DISABLE and SMB status shows as 1 But still showing SMB1 security fail

Everything was rebooted.

Well, I regressed to 4.2.6 build 20220623 and the problem still exists.

Code: Select all

[~] # smb2status
smbd (samba daemon) Version 4.0.25
smbd (samba daemon) is running.
max protocol SMB 1 enabled.
But no messages in the log.

The goal is to allow XP access to the data.

I found when I set SMB2 higher level windows get access but with SMB1 set (even after downgrading back to Firmware version 4.2.6 Build 20220623) neither XP nor higher windows can access.

Looks like 4.2.6 build 20221028 did something irreversible.

Also, I don't see Samba or the option to set down SMB in control panel. I had to do it via putty. I wonder if doing it this way skips something.

SMB1 should enable access for XP but will prevent access for WIn10/11 as SMB1 is disabled for security reasons (it can be re-enabled if you need to).

SMB control options are not available in GUI for old CAT1 NAS, so they have to be set via SSH.

Well, before the upgrade all windows were able to talk to the NAS. With SMB1 set (SMB2DISABLE command) neither XP nor other windows can access it.

It looks like build 20221028 did something not obviously reversible, i.e., was not reversed by putting 20220623 back on).

Are there some putty commands that will set SMB back to how it worked with 20220623, i.e., all windows machines have access? Perhaps it wasn't thru Samba but some other communication method which I do not know how to set.

enable SMB1 on your newer windows version(s) to see if they have access that way (so this way you know if SMB1 works or not)
