AltaLink C8000 series Fax Foward to SMB issue

Product Name: AltaLink C8070/C8055/C8035
Operating System: Windows 10 x64

Trying to get fax forwarding working and failing miserably. We previously had a Xerox WorkCentre 7970 that worked flawlessly via SMB to our Synology D115j NAS. I took screenshots and had it documented how it had it setup.

Protocol: SMB
IPv4 Address: 192.168.1.xxx:445
Share: Fax
Document Path: \
Login Name: USERNAME_HERE
Password: PASSWORD_HERE

That worked great until we "upgraded" to the AltaLink C8000 series (we have the C8070, C8055, and C8035). Following the same exact settings results in:
"Failed: Cannot Login into destination server using credentials provided."

I know the credentials work, I can map the drive to my computer, and access the share just fine. I have enabled SMB1, SMB2, and SMB3 on the Xerox side to no avail. I have it down to just SMB1 right now with no change. The NAS has SMB1-SMB3 enabled. I have the Xerox encryption set from TLS 1.0 up to 1.2 and back again. The firmware for the C8070 was updated recently to 101.003.069.20900 but that hasn't helped. The NAS has no firewall enabled, the IPs of the Xerox's have been whitelisted. The logs on the NAS don't even register a failed attempt to connect. The SMB log in the Synology doesn't register anything either, but I think it only logs file read/write/delete. I got the Xerox to (ONE TIME) connect successfully but it had a dummy folder setup and I was grasping at straws at the time and lost what settings I was using. I know the device is capable of SMB3, as noted by the ONE time it connected properly:

Log from the NAS (had incorrect document path, was testing without a slash)
Failed: Cannot write to \\192.168.1.xxx:445\Faxtest\SampleFile.pdf
Level: Info
Log: Connection
Date & Time: 2019-08-23 15:37:53
User: Fax
Event: User [Fax] from [XRXxxxxxxxxA0D(192.168.1.xxx)] via [CIFS(SMB3)] accessed shared folder [Fax].

<TransferAuthentication>
<AuthenticationType>SMB</AuthenticationType>
<LoginSuccess>true</LoginSuccess>
<NumberOfRetries>0</NumberOfRetries>
</TransferAuthentication>
</Event>

Every attempt before and after that has only resulted in this:

<Timestamp8601>2019-08-19T16:37:09.063-05:00</Timestamp8601>

<AuthenticationType>SMB</AuthenticationType>
<LoginSuccess>false</LoginSuccess>
<NumberOfRetries>0</NumberOfRetries>
<FailureReason>Login name/password/acccount failed</FailureReason>
</TransferAuthentication>
</Event>

What am I doing wrong? How can I get this working again? At this point I think I have tried every variation of share and document path and have run out of ideas.

Re: AltaLink C8000 series Fax Foward to SMB issue

By chance do you need to be using DOMAIN\username or username@DOMAIN for the login name?

Re: AltaLink C8000 series Fax Foward to SMB issue

Negative, we aren't using any domains or Microsofot networking permissions. The Synology is Linux based and is handling the permissions for the folder itself.

Re: AltaLink C8000 series Fax Foward to SMB issue

Need to set registry subkey,

Follow the below Process:(windowserver)

https://notesfromchad.wordpress.com/category/windows-security/

SETSPN -a host/windowscomputer.contoso.com windowscomputer

Next, Windows needs to allow that other dns name, this can be done by opening regedit:

  1. Locate the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters
  2. On the Edit menu, point to New, and then click Multi-String Value.
  3. Type SrvAllowedServerNames, and then press ENTER.
  4. On the Edit menu, click Modify.
  5. Add the host names in FQDN format, host names in NetBIOS format, or IP addresses that you want to be allowed as SPNs windowscomputer.contoso.com
  6. Then Click OK and Edit the registry.

=============================================================================

For Netapp server follow the belowsettings:

https://kb.netapp.com/app/answers/answer_view/a_id/1032147/~/how-to-set-up-kerberized-nfs-access-for...

setspn -A host/solaris-5.mylab.netapp.com user5host
Key:             solaris-5.mylab.netapp.com
Domain:      mylab.netapp.com
Hostname:  Solaris-5

example:

C:UsersAdministrator>setspn -A host/solaris-5.mylab.netapp.com user5host .... so on

Please Let us know whether it solve this issue or not.

Note: seting need to done in server end.

Re: AltaLink C8000 series Fax Foward to SMB issue

I ended up reaching out to Xerox directly and I have been working with them for the past couple of months (almost a year now) to get this resolved. They developed one firmware patch which didn't fix it. They are currently working on another firmware patch sometime in June. Hopefully it will be fixed then.

Re: AltaLink C8000 series Fax Foward to SMB issue

@psab, thanks for the quick responce.

As per your notes they replace device A to B and you have same envirement .

i expet this might have some authentication issue which you are come accross and device B failed to do authenticate this.

Authentication Log from Xerox
<Event>
<TimestampMillis>1566247029063</TimestampMillis>
<Timestamp8601>2019-08-19T16:37:09.063-05:00</Timestamp8601>
<TransferAuthentication>
<AuthenticationType>SMB</AuthenticationType>
<LoginSuccess>false</LoginSuccess>
<NumberOfRetries>0</NumberOfRetries>
<FailureReason>Login name/password/acccount failed</FailureReason>
</TransferAuthentication>
</Event> 

 

Please try to do SPN settings in Server to overcome this issue.which i described in my previous notes.

I understand developement team will give solutions , thats ok. but i want you try this so that if others will face this we can give solutions to them.

hope you are understanding this point.

Re: AltaLink C8000 series Fax Foward to SMB issue

@vish

I appreciate the help but I'm not going to try this solution as I am already working with Xerox directly. I don't want to change anything in the middle of them trying to resolve the issue.

If you read my original post, I'm connecting to a Synlogy NAS. But what I failed to mention is, there is no Windows Server, we do not use Active Directory, and there is nowhere to configure SPN. So I can't try this solution even if i wanted to.

As it stands now, Xerox has confirmed that the system is not properly sending the credentials to the NAS in the first place which is why they are working on a patch to the firmware. So if you want a solution for the future, anyone else that runs into this issue, they will need to wait for the patch to the firmware.
